Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The invention provides a network map layout method, which mainly aims at the problems that in the prior art, when a network map is analyzed, complicated operation steps need to be executed, the time is long, and the efficiency is low. According to the network map layout method provided by the invention, firstly, the target nodes and the event parameters are determined according to the operation of the user in the network map, then, the target layout mode corresponding to the event parameters is determined according to the preset rule, and the target nodes are rearranged according to the target layout mode, so that the operation steps are simplified, the analysis efficiency is improved, the time of the user is saved, and the use experience of the user is improved.
The network map layout method proposed by the embodiment of the present invention is described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a network map layout method according to an embodiment of the present invention.
As shown in fig. 1, the network map layout method may include the following steps:
s101, determining a target node and an event parameter according to the operation of a user in a network map.
Specifically, the network map layout method provided in this embodiment may be executed by the network map layout apparatus provided in the present invention, and the apparatus may be configured in a visualization device to implement the target node re-layout according to the requirement of a user.
The visualization device may be, but is not limited to, a computer (computer), a Personal Digital Assistant (PDA), and the like.
The target node may be a node of any one of the network maps.
Before executing S101 of the present invention, the network map layout method of the present invention further includes:
and determining that the user performs preset operation on the target node.
The preset operation may be a double-click operation, a circle-drawing operation, and the like, which is not specifically limited in this embodiment.
For example, when a double-click action of an external device (such as a mouse) on a certain node in the network graph is detected, it can be determined that the user performs a preset operation on the target node.
For another example, when it is detected that the external device performs a circling motion on a certain node in the network graph, it may be determined that the user performs a preset operation on the target node.
And/or determining that the user triggers a preset shortcut key when the focus is at the target node.
The preset shortcut key may be a single key, or a combination of any two or three keys, and the present invention is not limited to this. For example, Alt + Shift, etc.
For example, when an Alt + Shift signal is input while the external device is detected to move the cursor to a certain node in the network map so as to determine the focus on the node, it is determined that the user triggers a preset shortcut key.
Furthermore, the target node and the event parameter can be determined according to the operation of the user in the network map.
It should be noted that, a user may select any node as a target node by performing a preset operation on the node; or, when any node acquires the focus, the node can be selected as the target node by triggering the shortcut key; or, a preset shortcut key may be triggered to select a certain node as a target node while a preset operation is performed on the node.
It can be understood that when the user performs a preset operation on the target node and/or triggers a preset shortcut key, it indicates that the user performs the operation in the network graph, and further the target node and the event parameter can be determined according to the operation of the user.
The event parameter may include an event triggering manner, for example, the event parameter may be triggered by a mouse, a keyboard, a screen, or the like, which is not limited in this embodiment.
It can be understood that when the user performs different operations on the target node, the corresponding event parameters are different, and the corresponding purposes are different.
S102, determining a target layout mode corresponding to the event parameter according to a preset rule.
Specifically, in actual use, an FR (fuzzy-regrind) algorithm or a Force-guided Layout algorithm (Force-directed Layout) may be used to perform calculation based on the determined event parameters, so as to obtain a target Layout mode corresponding to the event parameters.
The FR algorithm is a layout algorithm for improving a force-guided layout algorithm, and belongs to the category of force-guided layout algorithms. It can be understood that the target layout mode corresponding to the event parameter can be quickly obtained through the algorithm, so that the corresponding target layout mode fully shows the overall structure of the network.
And obtaining a corresponding target layout mode according to the event parameters according to rules preset in the visualization equipment.
For example, when the event parameter is triggered by a mouse, the corresponding target layout manner is to layout the target node and the associated other nodes in a star manner.
The layout manner may be a star layout manner, a tree layout manner, a force guiding layout manner, and the like, which is not particularly limited in the present invention.
S103, re-arranging the target nodes according to the target arrangement mode.
Specifically, after the target layout mode corresponding to the event parameter is determined, the target nodes of the network map can be rearranged, so that a user can visually check the network relationship between the target nodes and other nodes.
For example, when the target layout manner is a star layout, the target node may be placed at a central position, and other nodes associated with the target node are distributed around the target node to form a star.
According to the network map layout method provided by the embodiment, the target nodes and the time parameters are determined according to the operation of the user in the network map, the target layout mode corresponding to the event parameters is determined according to the preset rule, and then the target nodes are rearranged according to the determined target layout mode. Therefore, the operation steps of the user are simplified, the overall efficiency is improved, the time of the user is saved, and the user is promoted.
FIG. 2 is a flow diagram of a network map layout method according to another embodiment of the present invention.
As shown in fig. 2, the network map layout method according to the embodiment of the present invention may include the following steps:
s201, determining a target node and an event parameter according to the operation of a user in a network map.
S202, determining a target layout mode corresponding to the event parameter according to a preset rule.
S203, the target node and the related leaf node are rearranged.
It should be noted that how many nodes of the network map are in the display interface of the visualization device directly affects the effect of the rearrangement between the target node and the associated leaf node. Therefore, in the actual use process, different operations can be executed according to the number of network map nodes in the display interface of the visualization device, so that the final layout can clearly and clearly show the network relationship between the target node and the associated leaf node.
In one scenario, if it is determined that there are fewer nodes of the network graph in the current display interface of the visualization device and the space between the nodes is relatively large, the target nodes and the associated leaf nodes may be directly rearranged in a target arrangement manner to obtain a network relationship graph between the target nodes and the associated leaf nodes.
In another scenario, if the number of nodes of the network map in the current display interface of the visualization device is large and each node is compactly distributed in a certain area of the display interface, the user can manually move the selected target node to a position where the space of the display interface of the visualization device is large, and then trigger automatic layout operation through a preset action to obtain a clear node network relationship result.
Or, the automatic network map layout device may determine the target node according to the operation of the user, then determine the position of the target node according to the position of the target node selected by the user and the positions of the nodes in the network map, and then re-layout the target node and the associated leaf nodes. That is, before S203, the network map layout method of the present invention further includes:
and S204, acquiring the position information of each node in the network map.
In specific implementation, the current position information of each node can be determined by looking up the data file of the network map.
S205, determining the position of the target node according to the position information and the event parameters of each node in the network map.
Specifically, the display forms of the network maps may be different due to the number of nodes in the network maps and the difference between the nodes. In the embodiment of the present application, in order to intuitively and clearly reflect the relationship between the target node and each of the other nodes in the rearranged network graph, the target node and the related leaf-type node may be "separated" from the other nodes in space.
It is understood that if the number of nodes in the network map is small, the location of the target node determined in step 205 may still be its original location. If the number of nodes in the network graph is large and the number of other nodes distributed near the target node is large, the target node can be moved out of the plurality of nodes, and the target node is taken as the center, and the target node and the leaf nodes are rearranged according to the arrangement mode corresponding to the event parameter, so that the arrangement result can clearly and concisely represent the network relationship between the target node and the associated nodes.
That is, step 205 is specifically:
determining the number of nodes to be moved and a target layout mode according to the event parameters;
determining the area of a target area according to the number of nodes to be moved and a target layout mode;
and determining the position of the target node according to the area of the target region.
The number of nodes to be moved refers to all nodes in the network graph which have direct network contact with the target node.
It should be noted that, in this embodiment, the target area refers to the size of a space required for completely displaying the target node and the node to be moved according to the target layout mode.
Specifically, after the area of the target region is determined according to the number of nodes to be moved and the target layout mode, the position of the target node can be determined according to the area of the target region.
For example, if the event parameter corresponds to an event: the target nodes and the corresponding leaf nodes are distributed in a star shape, so that the size of the space required by the display can be determined according to the number of the leaf nodes, and the suitable positions of the target nodes, such as the central position, can be determined according to the size of the space.
And S206, moving the target node to the determined position.
Specifically, after the position of the target node is determined, the target node may be moved to the position to perform rearrangement on the target node, so that the user may visually view the network relationship between the target node and other nodes.
It will be appreciated that the non-leaf node locations do not change when the target node is moved out of the network graph for re-layout.
In the embodiment of the present invention, the effect schematic diagram of the above steps S201 to S206 is shown in fig. 3. Fig. 3-a is a schematic diagram illustrating a moving position P of a target node determined according to the target node a and an event parameter, fig. 3-B is a schematic diagram illustrating a leaf-type node associated with the target node a before moving after the target node a moves to the corresponding position P, and fig. 3-C is a schematic diagram illustrating a layout effect after the target node and the associated leaf-type node are rearranged.
In a possible implementation form of this embodiment, if it is determined that the number of nodes irrelevant to the target node in the network graph is small according to the event parameter, in order to increase the speed of node layout, the node irrelevant to the target node may be removed from the area where the target node is located, and then the positions of other nodes relevant to the target node may be adjusted. This embodiment is not limited to this.
Further, in a possible implementation form of the present application, after the target node is rearranged according to the event parameter, the network map layout apparatus may still adjust the position of the target node according to the need, that is, the method may further include:
and updating the position of the target node according to the operation of the user on the target node.
Specifically, because there is a difference between the usage habits of the users, after the target node is moved to a suitable position according to the area of the target area, the users may not adapt to the target node during browsing, and the usage experience is not good. Therefore, after the target nodes are rearranged, the positions of the target nodes can be updated according to the operation of the user on the target nodes, so that the use experience of the user is improved.
It can be understood that the target node is moved to the position where the target node is used to browse by manual operation of the user, and then the target node is rearranged according to the updated position, so that the user can check the network relation between the target node and other nodes, the requirements of the user are met, and the use experience of the user is further improved.
In the network map layout method provided in this embodiment, before the target node and the associated leaf node are re-laid, the location information of each node in the network map is obtained, the location of the target node is determined according to the location information of each node and the event parameter, and then the target node is moved to the corresponding location. Therefore, the operation steps of the user are simplified, the overall efficiency is improved, the time of the user is saved, and the user experience is improved. In addition, the position of the target node can be updated according to the operation of the user, so that the user experience is further improved.
