Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

It should be noted that, in the present invention, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order; the terms "S101", "S102", "S201", "S202", etc. are used to distinguish the steps and are not necessarily to be construed as performing method steps in a particular order or sequence; when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

First, an application scenario of the present invention will be explained. The invention can be applied to a map scaling scene, wherein a map refers to a relationship network obtained by connecting a plurality of different kinds of information together, and the relationship network consists of nodes and connecting lines among the nodes, each node represents an entity existing in the real world, each connecting line is a relationship between the entities, for example, the map can be a social relationship diagram of an enterprise, different nodes can be different enterprises, and each connecting line can represent a social relationship between every two enterprises, such as relationships of investment, job, patents, bid and complaints.

Generally, when a graph is displayed, the graph is displayed according to a global display style by default, that is, all nodes and connecting lines of the whole graph are displayed on a display page, however, because the number of enterprises may be large, the social relationship among the enterprises may also be complex, the globally displayed graph includes a large number of nodes and connecting lines, and because the display range of the display page is limited, the size of the node display is small, the display of the connecting lines also appears cluttered, at this time, if a user needs to clearly view the social relationship of a specific enterprise, the graph needs to be amplified, so that the user can conveniently view local contents of the graph, and after the user finishes viewing, the amplified graph can be reduced, and the graph is displayed globally. And vice versa, and will not be described in detail herein.

It should be understood that only one node may be included in the graph without connecting lines between nodes, and that, taking the enterprise social relationship graph as an example, there may be only one enterprise in the graph without any relationship to other enterprises or individuals.

In the related art, when a user performs a zoom operation (a zoom-out operation and a zoom-in operation) on an atlas, the user directly performs the zoom operation with an operation focus of the user as a zoom central point, the zoom mode is relatively single and low in flexibility, and when the operation focus of the user is located at a border or other blank areas of the atlas, the zoom operation performed on the atlas by the user cannot achieve any effect of facilitating the user to view the atlas, so that the effectiveness of the zoom operation of the user is low, and the experience of the user in viewing the atlas is reduced.

Taking the social relationship diagram of the enterprise as an example, when a user wants to view the social relationship of a target enterprise in a map, the user may perform an enlarging operation on the map, but an operation focus of the user is located at a boundary or other blank areas of the map, and at this time, if the user directly performs zooming with a focus position of the operation focus of the user in the map as a zooming center point, the displayed content after zooming is the boundary or other blank areas of the map, that is, the zooming operation of the user does not have an effect of viewing the map, so that the effectiveness of the zooming operation is reduced, and the experience of the user in quickly and accurately viewing the map is also reduced. In addition, in the process of scaling the map, the user cannot flexibly and timely adjust the scaling central point according to the change of the operation focus of the user, and the user must perform the next scaling operation after the scaling process is completed, which results in poor flexibility and user experience of the map scaling mode.

In order to solve the above problem, embodiments of the present invention provide a map scaling method, an apparatus, a storage medium, and an electronic device, which can flexibly adjust a scaling central point to a target map node around a focus position, thereby not only improving effectiveness of a user scaling operation, but also facilitating a user to quickly and accurately check the target map node around the focus position, improving user experience, and in addition, when it is determined that an operation focus of the user changes during a scaling process, re-determining the target map node to continue scaling, thereby improving flexibility and user experience.

The following detailed description of embodiments of the invention refers to the accompanying drawings.

Fig. 1 is a method for map scaling according to an embodiment of the present invention, and as shown in fig. 1, the method may include:

step S101: and in response to the zooming operation of the user on the displayed target map, determining the focal position of the operation focus of the user in the target map.

Wherein the target graph may include at least one node. For example, the target graph may be a business social relationship graph in which nodes are used to represent a central business or a target business, and connections between nodes are used to represent social relationships between two businesses, such as investments, duties, patents, bids, and complaints. When the user is interested in the social relationship of the target enterprise, the target graph can be zoomed to clearly view the social relationship of the target enterprise.

In the present embodiment, the type of the zoom operation may include a zoom-in operation and a zoom-out operation, wherein the zoom-in operation is used to zoom in on the atlas; the reduction operation is for reducing the map.

In an alternative implementation, the zoom operation may include a user scrolling operation on a mouse wheel. Illustratively, the user triggers a zoom-in operation in the case of scrolling the mouse wheel in a first direction, and triggers a zoom-out operation in the case of scrolling the mouse wheel in a second direction, wherein the first direction and the second direction are opposite directions.

In another alternative implementation, the zoom operation may include a trigger operation of the user on a displayed zoom key. For example, if the display page of the target map can be provided with an enlargement button and a reduction button, the enlargement operation is triggered when the user clicks the enlargement button, and the reduction operation is triggered when the user clicks the reduction button. Specifically, when a user triggers a full-screen mode, an enlargement button and a reduction button are added in a target atlas, if the user clicks the enlargement button, enlargement operation is triggered, and if the user clicks the reduction button, reduction operation is triggered.

In the case that the zooming operation includes a scrolling operation of the mouse wheel by the user, the operation focus may be a mouse cursor, and a position of the mouse cursor in the target map may be used as a focus position, and the user may adjust the focus position by moving the mouse. As shown in fig. 2a, taking the enterprise social relationship graph as an example for explanation, a circle in the graph represents each node, and a connecting line between every two nodes represents the social relationship between the two nodes, so that in fig. 2a, a position of a cursor of a mouse is a focus position.

In the case that the zooming operation includes a triggering operation of a user on a displayed zooming key, the operation focus may be a focus frame, and then a position of the focus frame in the target map may be used as a focus position, and the user may adjust the focus position through a direction control key on the keyboard. As shown in fig. 2b, still taking the enterprise social relationship graph as an example for illustration, a focus frame may be displayed on a display page of the target graph, and the user may control the focus frame to move on the display page through a direction control key on a keyboard, where the zoom key includes a "+" key for enlarging the graph and a "-" key for reducing the graph, the user may click the corresponding keys through a mouse to enlarge and reduce the graph, the position of the focus frame is the above-mentioned focus position, the user may control the movement of the focus frame through the direction control key, for example, the direction control key may be four direction control keys on the keyboard, such as "×", "↓", "←", and "→", when the user triggers the "↓" key, the focus frame may move to the upper side of the display page, when the user triggers the "↓" key, the focus frame may move to the lower side of the display page, when the user triggers the "←" key, the focus frame can be moved to the left of the presentation page, and when the user triggers the "→" key, the focus frame can be moved to the right of the presentation page, thereby adjusting the focus position of the operation focus of the user.

Step S102: and determining target graph nodes from the nodes in the target graph according to the focus position.

In some embodiments, a node at a focal position may be considered a target graph node if there is a node at the focal position. In the embodiment, because the node exists in the focus position, the node existing in the focus position is most likely to be the node that the user wants to view (such as the node that the user is interested in), and this way, the step of selecting the zoom central point by the user can be omitted, the time taken for zooming and viewing is reduced, and the efficiency is improved.

In other embodiments, in a case where there is no node at the focus position, considering that nodes closer to the focus position may become nodes that the user wants to view, a node that is the shortest from among the nodes to the focus position may be taken as the target graph node. The method can save the step of selecting the zooming central point by the user, reduce the time spent on zooming and checking and improve the efficiency.

For example, when there is no node at the focal position, the distance between each node and the focal position may be obtained, and the node with the shortest distance is determined to be an undetermined node, where the undetermined node may include at least one node; and determining a target map node according to the undetermined node.

It should be noted that, because there may be one or more undetermined nodes with the shortest distance from the focal position, when there is one undetermined node, the undetermined node is used as a target graph node; or, under the condition that a plurality of undetermined nodes are provided, the undetermined node with the shortest distance to the preset position in the target map is used as the target map node.

Specifically, when a plurality of nodes to be determined are provided, that is, a plurality of nodes with the shortest distance from the focal point position are provided, at this time, the distance between each node to be determined and the preset position may be calculated, and the node to be determined with the shortest distance may be used as the target graph node. Therefore, under the condition that the node with the shortest distance to the focus position is multiple, the target map node can be determined through the distance from the preset position, and the condition that the target map node cannot be determined when the undetermined node is multiple is avoided.

In addition, in the case that the distances between the plurality of nodes to be determined and the preset position are the same, the plurality of nodes to be determined having the same distance from the preset position may be highlighted in the target graph spectrum, and the user may select one of the plurality of nodes to be determined as the target graph node, or may randomly select any one of the plurality of nodes to be determined as the target graph node.

For example, the preset position may include a center position of the target atlas, and a person skilled in the art may select the position of the preset position according to actual needs, which is not limited by the present invention. Also, the preset position may be selected in advance by a user or randomly.

In view of the fact that, when the target graph includes a large number of nodes, calculating the distance between each node and the focal point may cause excessive consumption of processing resources and reduce the graph scaling efficiency, in another embodiment of the present invention, in order to solve the problem, when it is determined that a candidate node exists within a preset range around the focal point, a node that is the shortest from the focal point among the candidate nodes may be used as a target graph node, where the candidate node is a node within the preset range around the focal point. Therefore, the node with the shortest distance to the focus position is determined from the nodes in the preset range around the focus position, and the distance between each node in the target map and the focus position does not need to be acquired, so that the consumption of processing resources is reduced, and the map scaling efficiency is improved.

In the case that the number of candidate nodes is one, the candidate node may be used as a target graph node, that is, in the case that the number of candidate nodes is one, the candidate node is a node that the user wants to view.

When the number of the candidate nodes is multiple, determining a node which a user wants to view from the multiple candidate nodes, wherein an optional implementation mode is that one node is randomly determined from the multiple candidate nodes to serve as a target graph node; another optional implementation manner is to use a node with the shortest distance to the focus position in the plurality of candidate nodes as the target graph node, for example, a first coordinate of the focus position in the target graph and a second coordinate of each candidate node in the target graph may be obtained, the distance between the focus position and each candidate node is calculated according to the first coordinate and the second coordinate, and the candidate node with the shortest distance is used as the target graph node.

Of course, in the case that the number of candidate nodes is multiple, the present embodiment may also use the candidate node that is the shortest distance from the preset position as the target graph node. In the case where the distances between the plurality of candidate nodes and the preset position are also the same, the user may select one of the plurality of candidate nodes as the target graph node by highlighting the plurality of candidate nodes having the same distance from the preset position in the target graph, or randomly select any one of the plurality of candidate nodes as the target graph node.

In addition, in the case where it is determined that there is no candidate node within a preset range around the focus position, a node that is the shortest distance from the focus position among the nodes may be taken as a target graph node. It should be understood that the specific method for determining the target graph node is the same as the specific method for determining the target graph node in the case that no node exists at the focal position, and the detailed description thereof is omitted here.

Optionally, the method of this embodiment further includes: and refusing to respond to the zooming operation under the condition that the candidate node does not exist in the preset range around the focus position. Under the condition that no candidate node exists in the preset range around the determined focus position, the node which the user wants to view on the target map may not exist, and the zooming operation at the moment may be misoperation.

Step S103: and according to the zooming operation, zooming the target map by taking the target map node as a zooming central point.

Because the target map node is a node which the user wants to view, the target map is zoomed by taking the target map node as a zooming central point, and the target map can be zoomed flexibly according to the node which the user wants to view.

It should be noted that, considering that most of the operations on the map are performed by a mouse at present, for a case that the zooming operation includes a trigger operation of a user on a displayed zooming key, a focus frame may not exist on the displayed page, and based on this, in other embodiments, when the zooming operation includes a trigger operation of a user on a displayed zooming key, the target map may be zoomed by using the center position of the target map as the zooming center point according to the zooming operation. In this way, different scaling operations can select different scaling processing modes, so that the map is more flexibly scaled.

Step S104: and under the condition that the operation focus of the user is determined to be changed in the zooming processing process, re-determining the target graph node to continue the zooming processing.

As shown in fig. 3, step S104 may specifically include the following steps:

step S1041: interrupting the zooming processing and determining the focus position of the operation focus of the user in the target map under the condition that the operation focus of the user is determined to be changed in the zooming processing process;

step S1042: determining target graph nodes from nodes in the target graph again according to the focal position;

step S1043: and continuing to zoom the target map by taking the re-determined target map node as a zooming central point.

Optionally, step S1042 specifically includes: and under the condition that the operation focus of the user stays at the focus position for a preset time, re-determining the target map nodes from the nodes in the target map according to the focus position. Optionally, the preset time is a preset time period, for example, the preset time may be 0.5 second, and a person skilled in the art may select the preset time period according to actual needs, which is not limited herein.

Specifically, a zoom process is taken as an example for explanation, in the process of the zoom process, if it is monitored that the operation focus of the user changes, the current zoom process is interrupted, and the focus position of the current operation focus of the user in the target map is determined; re-determining target graph nodes from nodes in the target graph according to the re-determined focal position; and continuing the previous amplification processing on the target map by taking the newly determined target map node as a zoom central point, namely recovering the previous amplification processing.

It should be noted that, in the case that it is determined that the operation focus of the user changes in the zooming process, the method in this embodiment may complete switching and zooming of multiple target graph nodes in one zooming process, which not only omits the step of repeatedly obtaining the zooming operation of the user, but also makes zooming of the target graph more flexible and better meets the current requirements of the user.

By adopting the scheme, the zooming central point can be flexibly adjusted to the target map nodes around the focus position, so that the effectiveness of the zooming operation of a user is improved, the user can conveniently and quickly and accurately check the target map nodes around the focus position, the user experience is improved, the target map nodes can be redetermined to continue the zooming processing under the condition that the operation focus of the user is determined to be changed in the zooming processing process, and the flexibility and the user experience are improved.

Fig. 4 is a flowchart of another atlas scaling method provided in the embodiment of the invention. As shown in fig. 1 and 4, the atlas scaling method shown in fig. 1 differs from the atlas scaling method shown in fig. 4 only in that: step S103 may specifically include the following steps:

step S1031: and determining a scaling type corresponding to the scaling operation.

Wherein the zoom type includes zoom-in and zoom-out.

Step S1032: a scaling rate corresponding to the scaling type is obtained.

The zooming rate is used for representing the zooming multiple of each operation when a user uses zooming operation, and different zooming types correspond to different zooming rates.

In an optional implementation manner, the zoom rate includes a first zoom rate and a second zoom rate, and in a case that it is monitored that a zoom operation performed on the target map by the user is an enlargement operation, the enlargement operation is performed on the target map according to the first zoom rate, for example, the first zoom rate may be set to 1.03, that is, the size of each enlargement is 1.03 times of the size of the previous and next; in a case that it is monitored that the scaling operation performed on the target map by the user is a scaling-down operation, the scaling-down operation is performed on the target map according to a second scaling rate, for example, the second scaling rate may be set to 0.95, that is, the size of each scaling-down operation is 0.95 times of the size of the previous and next scaling-down operations.

Step S1033: and taking the target map node as a scaling central point, and scaling the target map according to the scaling rate.

In an example, after the target graph node and the scaling rate are obtained, the target graph is scaled according to the scaling rate by using the target graph node as a scaling center. For example, after a certain target enterprise in the enterprise social relationship graph is determined to be a target graph node, a scaling operation of a user on the target graph is monitored, a corresponding scaling rate is obtained according to the scaling operation, then the obtained first scaling rate or second scaling rate is used as a scaling parameter of a scaling function in a graph layer and is input, and the target graph is scaled by the scaling function.

Further, under the condition that the magnification of the target map reaches a preset magnification, if the magnification operation of the target map by the user is monitored, refusing to respond to the magnification operation; or, under the condition that the reduction multiple of the target map reaches the preset reduction multiple, if the reduction operation of the user on the target map is monitored, the response of the reduction operation is refused. Therefore, by setting the upper limit of the zoom times of the zoom operation, the phenomenon that the atlas is infinitely zoomed to influence the user experience can be avoided.

For example, the preset reduction factor may be set to 0.5 times of the original target map, and the preset magnification factor may be set to 1.5 times of the original target map; for example, after the target atlas is enlarged to 1.5 times of the original target atlas, if the enlargement operation of the target atlas performed by the user is continuously monitored, the response to the enlargement operation is rejected. Similarly, after the target map is reduced to 0.5 times of the original target map, if the reduction operation of the user on the target map is continuously monitored, the response of the reduction operation is refused.

By adopting the scheme, the zooming central point can be flexibly adjusted to the target map node around the focus position, the effectiveness of the zooming operation of a user is improved, the user can conveniently and quickly and accurately check the target map node around the focus position, the user experience is improved, the target map node can be re-determined to continue the zooming processing under the condition that the operation focus of the user is determined to be changed in the zooming processing process, the flexibility and the user experience are improved, the corresponding zooming operation can be executed according to the zooming request of the user when the zooming operation is executed, in the process of executing the corresponding zooming operation, different zooming rates can be corresponding, the target map cannot be ignored when being zoomed, the zooming has 'frustration', and the smooth experience of the user in the zooming process is guaranteed. And by setting the upper limit of the zoom times of the zoom operation, the target map can be prevented from being infinitely zoomed, and the user experience is prevented from being influenced.

In addition to the above differences, other descriptions can be made with reference to the description of the map scaling method shown in fig. 1, and are not repeated here. It should be understood that steps S1031 to S1033 in fig. 4 may also be applied to the map scaling method shown in fig. 3, and are not described herein again.

Fig. 5 is a flowchart of another atlas scaling method provided in an embodiment of the present invention, and as shown in fig. 5, the method may include:

step S501: and obtaining the zooming operation of the user on the displayed target map.

Wherein the target graph comprises at least one node.

The zooming operation comprises the triggering operation of a displayed zooming key by a user or the rolling operation of a mouse wheel by the user. The type of the zoom operation may include a zoom-in operation for zooming in the atlas and a zoom-out operation for zooming out the atlas.

In an alternative implementation, in the case that the zooming operation is a scrolling operation of the mouse wheel by the user, step S502 is performed. Illustratively, the user triggers a zoom-in operation in the case of scrolling the mouse wheel in a first direction, and triggers a zoom-out operation in the case of scrolling the mouse wheel in a second direction, wherein the first direction and the second direction are opposite directions.

Step S502: and taking the position of the mouse cursor in the target map as a focus position.

In the case that the zooming operation includes a scrolling operation of the mouse wheel by the user, the operation focus may be a cursor of the mouse, and a position of the cursor of the mouse in the target map may be used as a focus position, and the user may adjust the focus position by moving the mouse.

Step S503: and acquiring the distance between each node and the focus position, and determining the node with the shortest distance as the node to be determined.

If the number of the nodes to be determined is one, executing step S504; if there are a plurality of pending nodes, step S505 is executed.

Step S504: and taking the node to be determined as a target map node.

And under the condition that one undetermined node is used, taking the undetermined node as a target graph node, namely, calculating the distances between the positions of all nodes on the target graph and the focus position, then comparing all the obtained distances, taking the node with the shortest distance to the focus position as the undetermined node, wherein only one undetermined node with the shortest distance to the focus position is used at the moment, and taking the undetermined node as the target graph node.

Step S505: and taking the undetermined node with the shortest distance to the preset position in the target map as the target map node.

And in this case, the node positions of the nodes with the same shortest distance are compared with the distance of the preset position, and the node with the shortest distance to the preset position is obtained and used as the target map node. Wherein, the preset position may include a central position of the target atlas.

Step S506: and determining a scaling type corresponding to the scaling operation.

Wherein the zoom type includes zoom-in and zoom-out.

Step S507: a scaling rate corresponding to the scaling type is obtained.

Wherein different zoom types correspond to different zoom rates. In an optional implementation manner, the scaling rate includes a first scaling rate and a second scaling rate, and when it is monitored that the scaling operation performed on the target map by the user is an amplification operation, the target map is amplified according to the first scaling rate. For example, the first zoom rate may be set to 1.03, i.e., the size of each zoom is 1.03 times the size of the previous and next zoom; and under the condition that the scaling operation of the target map performed by the user is monitored to be a scaling-down operation, scaling-down operation is performed on the target map according to a second scaling rate.

In another optional implementation manner, in a case that the zooming operation is a triggering operation of a user on a displayed zooming key, after the target graph node and the zooming rate are acquired, zooming processing is performed on the target graph directly with the central position of the target graph as a zooming central point according to the zooming rate.

step S601: and obtaining the zooming operation of the user on the displayed target map.

Wherein the target graph comprises at least one node,

In an alternative implementation, in the case that the zooming operation is a scrolling operation of the mouse wheel by the user, step S602 is performed. Illustratively, the user triggers a zoom-in operation in the case of scrolling the mouse wheel in a first direction, and triggers a zoom-out operation in the case of scrolling the mouse wheel in a second direction, wherein the first direction and the second direction are opposite directions.

Step S602: and taking the position of the mouse cursor in the target map as a focus position.

Step S603: whether a candidate node exists within a preset range around the focus position is determined.

In a case where it is determined that there is a candidate node within a preset range around the focus position, step S604 is performed.

Step S604: the number of candidate nodes is determined.

The candidate nodes are nodes in a preset range around the focus position.

In the case where the number of candidate nodes is one, step S605 is executed; in the case where the number of candidate nodes is plural, step S606 is executed.

Step S605: and taking the candidate nodes as target graph nodes.

In this step, when the number of candidate nodes is one, the candidate nodes may be used as target graph nodes, that is, when the number of candidate nodes is one, the candidate nodes are nodes that the user wants to view.

Step S606: and acquiring the distance between the position of each candidate node and the focus position, and taking the candidate node with the shortest distance as a target map node.

Step S607: and determining a scaling type corresponding to the scaling operation. Wherein the zoom type includes zoom-in and zoom-out.

Step S608: a scaling rate corresponding to the scaling type is obtained.

Step S609: and taking the target map node as a scaling central point, and scaling the target map according to the scaling rate.

Step S610: and under the condition that the operation focus of the user is determined to be changed in the zooming processing process, re-determining the target graph node to continue the zooming processing.

Wherein, step S610 may specifically include: interrupting the zooming processing and determining the focus position of the operation focus of the user in the target map under the condition that the operation focus of the user is determined to be changed in the zooming processing process; determining target graph nodes from nodes in the target graph again according to the focal position; and continuing to zoom the target map by taking the re-determined target map node as a zooming central point.

Under the condition that no candidate node exists in the preset range around the focal position, after the target map node and the zooming rate are obtained, the target map is zoomed by directly taking the central position of the target map as the zooming central point according to the zooming rate, and the response of zooming operation can be refused.

In another alternative implementation, the zoom operation may include a trigger operation of the user on a displayed zoom key. When the scaling operation is the triggering operation of the user on the displayed scaling key, after the target graph node and the scaling rate are obtained, the target graph may be scaled by directly using the center position of the target graph as the scaling center point according to the scaling rate.
