Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a method for constructing a large data visualization screen, which comprises the following steps: creating a plurality of containers according to the size of the data visualization large screen; configuring components in containers, wherein the components are completely packaged and stored in a component library in advance, the sizes of the components are matched with those of the containers, and the number of the configured components in each container is one; and displaying the components configured in the containers on the data visualization large screen, thereby realizing the efficient construction of the data visualization large screen. The implementation details of the construction method of the data visualization large screen of the present embodiment are specifically described below, and the following description is only provided for the convenience of understanding, and is not necessary for implementing the present solution.
The method for constructing a data visualization large screen according to the embodiment is shown in fig. 1, and includes:
Specifically, one container can contain one component, if N components need to be displayed on a display page of the large data visualization screen, the number of the created containers is also N when the containers are created, and the created N containers can be used for fully covering the whole large data visualization screen, so that all display parts of the large screen are ensured to be used for displaying data, and the utilization rate of the large screen display parts is improved.
When a plurality of containers are created, the data visualization large screen can be divided into a plurality of same rectangular areas according to the size of the data visualization large screen, and the containers can be created according to the divided rectangular areas. The number of created containers can be set by using an initialization setting interface of a data visualization large screen, as shown in fig. 7, a plurality of large screen attributes and parameters are set on the initialization setting interface, a user can fill the resolution of the data visualization large screen to be created in an input frame corresponding to the large screen resolution, and fill the number of rectangular areas to be created in an input frame corresponding to the large screen size, such as 6 × 3, which indicates that 6 rectangular areas are set in the length direction, and 3 rectangular areas are set in the width direction. After the parameters are determined, the system automatically divides the large screen into 6 x 3 rectangular areas, each rectangular area is used as a container, and the creation of a plurality of containers is completed.
After creating several containers of the same size, the containers can be merged according to the need, and at least 2 containers are merged into a new container, for example, as shown in fig. 2, the size of each container before merging is the same as that of the container in the upper right corner of fig. 2, the container in the upper left corner of fig. 2 is merged by two containers in the horizontal direction, and the container in the lower left corner is merged by four containers in the vicinity of the container. When at least two containers are combined, the containers can be dragged and combined by adopting a third-party plug-in vue-grid-layout, and the at least two containers are combined, so that the sizes of the containers can be freely adjusted, and the purpose of large-screen multiple structural layout is achieved. After creating the container, the relationship of the container to the large screen is saved in the background database by id binding.
In practical application, a main container can be established according to the size of a display interface of a data visualization large screen, the size of the main container is the same as that of the display interface, then the main container is divided into M × N sub containers with the same specification according to the number of rectangular areas needing to be divided, and then the sub containers can be combined according to requirements. After creating the child containers, one component may be configured in each child container.
At step 102, components within a container are configured.
Specifically, when configuring a component within a container, as shown in FIG. 2, the option "please select a business component" may be clicked on, and the interface displays the names of a plurality of configurable components, such as "tourist location weather", "tourist pictures", etc., each component's name summarizing the meaning of the data presented by the component. The user selects the name of the desired component to determine the components configured within the container and the data exposed within the container. And selecting the data to be displayed in each container according to the requirement by the user, and adjusting the layout of the containers, thereby realizing the highly customized large-screen configuration.
All the components selected by the user are completely packaged and pre-stored in the component library, as shown in fig. 3 and 4, the components are diversified in style, including various types such as charts, maps and multimedia, and the data display form is rich. In addition, the data presented by each component has a specific meaning, such as data in FIG. 3 presenting tourist location weather, data in FIG. 4 presenting passenger information, and so on. In addition, because the components are completely packaged, the user does not need to configure the parameters of the components such as styles, custom animations and the like, and therefore the user without the relevant knowledge of webpage construction can also rapidly configure the components.
In addition, the size of the assembly is matched to the size of the container. The matching setting mode is that after the data visualization large screen is divided into a plurality of (M multiplied by N) same rectangular areas according to the size length multiplied by the width (srResX multiplied by srResY), the size of the length and the width of the rectangular areas is taken as a standard size and is recorded as 1 multiplied by 1, the pixel values of the length and the width of the standard size can be calculated according to the size of the data visualization large screen and the number of the divided rectangular areas with the length and the width, and the pixel value of the length of the standard size
Width pixel value
The aspect ratio of the components in the component library to the rectangular region is the same, and assuming that the standard size of the 1 × 1 component is set to length × width (C × D), a matching ratio of the size of the 1 × 1 container to the size of the 1 × 1 component can be obtained
Or
Because the component uses the relative value setting style of the CSS in the development stage, the self-adaptation of the large-screen component can be realized according to the matching proportion obtained by the calculation.
After configuration is confirmed, the current container layout is converted into a corresponding description configuration file, and the description configuration file is stored in a background database in a JSON format in a key value pair mode. The configuration file is mainly divided into two parts, wherein the first part records the name and the corresponding id of the current container, and the second part records the layout position information and the rendering key information of each component in the container. The position information is represented by four fields of left, top, w and h, and respectively represents the distance between the component and the left frame and the upper frame of the container and the width and height of the component. Since the large screen container is divided into a plurality of small blocks in a modularized manner, the length and width of the large screen container are all n based on a standard container of 1 × 1, and when left is 2, top is 0, w is 2, and h is 3, the length of the current component from the left side of the container is 2n, the distance from the top of the container is 0, the length of the component is 2n, and the height of the component is 3 n. In addition, the rendering key information records the names of the components and the id corresponding to the names, so that the corresponding components can be quickly found in the component library through the information, and the corresponding JS file is found in the mapping file of the component service.
And 103, displaying the components configured in the containers on a data visualization large screen.
And the rendering engine rapidly constructs a data visualization large screen by using the configuration file, finds the JS file corresponding to the component in the mapping file of the component service according to the layout configuration file, and injects the JS file into a large screen page. When a large-screen Document Object Model (DOM) structure is constructed, the scaled size (font-size value) is injected into the top-level DOM of the sub-container, and the final large screen can be obtained.
Compared with the prior art, the configured components are completely packaged and stored in the component library, when the data visualization large screen is constructed, the components placed in each container are directly selected from the component library to complete the configuration of the components, and finally the configured components are displayed on the data visualization large screen, so that the construction of the data visualization large screen can be completed, the components do not need to be configured in style, the operation is simple, the requirement of professional technology is not met, any user can construct the large screen, the large screen construction time is shortened, and the construction efficiency is improved. In addition, the components in the component library are matched with the created containers in size, and only one component is accommodated in each container, so that incomplete display of the components due to size mismatching is avoided, the components in the component library can be directly placed in the containers, the size of the components does not need to be adjusted by a user, and the efficiency of constructing the data visualization large screen is further improved.
The second embodiment of the present invention relates to a method for constructing a data visualization large screen, and in the second embodiment of the present invention, after creating a plurality of containers according to the size of the data visualization large screen, the method further includes: creating a large screen header; wherein, big screen head includes: a global component; the global component is used for switching the display content of the data visualization large screen, so that the display content of the large screen can be switched by utilizing the global component, and the display content is richer.
The method for constructing the data visualization large screen according to the embodiment is shown in fig. 5, and includes:
Specifically, when a data visualization large screen is constructed, an upper part and a lower part can be constructed, the upper part is a large screen head part and displays basic information and global components, the lower part is a large screen container for loading visualization components such as charts and the like, the container can be switched through a pull-down frame of the head part, the purpose of multi-page display is achieved, the switched content is the components displayed on each page configured by a user according to needs, the data dimension diversity is rich, and the displayed data themes are gathered clearly.
The created large screen header is shown in fig. 6, and the parameters contained in the large screen header include the current time "09 month by 2019, 24 days 16:25: 40", the large screen name "integrated detection analysis big data platform", and the global component. The global component is used for switching display contents of the data visualization large screen. For example, according to the large screen header shown in FIG. 6, the parameters of the global component include: region of interest (general analysis (whole), time dimension (by day), start time and end time (2019-09-23), region of interest (Xinjiang Uygur autonomous region). "belonging region" represents the source of the large screen data; the time dimension represents the time granularity of data screening, and a user can select multiple granularity queries of 'day', 'week', 'month', 'quarter', 'year' and 'holiday'; "start time" and "end time" represent the starting and ending time points at which large screen data can be queried for presentation, with no expiration time being defaulted by the system when the user has not selected an expiration time.
In practical application, the attribute and the parameter of the large screen are set through an initialization setting interface of the data visualization large screen, the initialization setting interface is shown in fig. 7, and the set parameters include: "large screen name", "belonging area", "welcome word", "large screen resolution", "large screen size", "time dimension", "start time", "end time", "automatic switching time", and the like. The rule of the large screen size set here is to set based on the layout of the containers to be set, and as shown in fig. 7, the layout of the containers in the large screen represents that the large screen is 3840px and 1080px in width, and the layout of the containers in the large screen is 6 × 3, that is, 6 containers with standard sizes are set in the length direction and 3 containers with standard sizes are set in the width direction. After the user initializes the web page on a large screen and sets basic attributes, the system stores the attributes and attribute values in a relevant background database in a key value pair mode.
At step 502, components within a container are configured.
And 503, displaying the components configured in the containers on a data visualization large screen.
And step 504, monitoring whether the parameters of the global component of the large-screen head change or not, and if so, re-determining the data displayed by the data visualization large screen according to the changed parameters of the global component.
Specifically, the functions of the global component include: and switching pages of the large screen and refreshing data displayed by the components in the large screen, wherein different functions are realized based on parameters of different global components. Furthermore, when the page of the large screen is switched, the display interfaces which are preset and stored in the database are called, each display interface comprises a plurality of containers, each container is configured with a component, a plurality of different display interfaces are stored in the database in advance, and each display interface is configured by a user through the steps 501 to 503 of creating the container and configuring the components. That is to say, when it is monitored that the parameters of the global components change, the display interfaces corresponding to the changed parameters are obtained in the database, and because the layout of the containers and the components configured in each container in different display interfaces are different, the display interfaces are switched to realize the display of different types of components. On the other hand, when the data displayed by the component is refreshed, the third party data stored in the database needs to be pulled, and the data displayed by the component is refreshed according to the third party data. The database is pre-stored with a plurality of groups of third party data corresponding to the same component, such as data describing the number of visitors in different time periods, and when the time parameter of the global component is changed, the data of the number of visitors displayed by the component is refreshed according to the changed time parameter. In summary, whether the data displayed on the data visualization large screen needs to be updated is determined by monitoring whether the parameters of the global component change, and if the parameters of the global component change, the display interface is reconfigured or the data displayed by the components in the container are refreshed according to the changed parameters of the global component. When a display interface is reconfigured or data displayed by components in a container are refreshed, the changed parameters of the global components can be used as data matched with the URL parameter request, and the components are re-rendered according to the data acquired from the background database, so that the effect of data linkage is achieved.
In practical application, the monitoring mode of the global component may be that a VUE framework is adopted to construct a large screen, Vuex is used to manage global component variables, a watch mechanism is used to set a corresponding monitoring relationship between a container and the monitored global component, for example, when a start time parameter of the global component is changed, a first container acquires data again, the first container monitors the start time parameter in the global component, and if the start time parameter is changed, a data request is sent to acquire data again.
The overall process of constructing the large data visualization screen is specifically described as follows by using a specific example:
firstly, setting the attribute and the parameter of a large screen in an initialization setting interface of a data visualization large screen, wherein the set parameter comprises a large screen name, a region to which the large screen belongs, a welcome word, a large screen resolution, a large screen size, a time dimension, a starting time, an ending time, an automatic switching time and the like. Therefore, the setting of basic attributes such as pixel values of the large screen and parameters of the head of the large screen is realized.
Secondly, a single or a plurality of large-screen main containers are created, each created large-screen main container is a display interface, each main container comprises a plurality of sub containers, and required components can be configured in the sub containers. In addition, each main container is provided with a container name, so that the corresponding display interface can be quickly found when the display interface is switched.
And then, dragging and combining the sub-containers contained in each main container, realizing the layout of the sub-containers in the main container, and configuring components in each sub-container.
And finally, the rendering engine rapidly constructs the data visualization large screen according to the configuration, so that the data visualization large screen is efficiently constructed.
After the data visualization large screen is constructed, the switching of the large screen display interface and the refreshing of the data displayed by the components in the large screen can be realized by changing the parameters of the global components in the head of the large screen, so that the display content is richer.
In this embodiment, a large-screen head is also created when constructing a large-screen for data visualization, and the large-screen head includes: a global component; the global component is used for switching the display content of the data visualization large screen, the purpose of multi-page display is achieved, the data dimension diversity is rich, and the displayed data theme is gathered clearly.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
