Detailed Description
The conventional configuration graph can realize fixed data association, namely once the pixel association is set and cannot be changed, the data definition requirement characteristic of transaction pixels in a multi-time period variable period cannot be met, so that the data association method breaks through the traditional data definition association mode and adopts a multi-dimensional data association mode. The data association method can enable the graphic primitive to associate the non-fixed association definition data, and the data definition associated with the graphic primitive can be changed along with the user picture operation; the display characteristic of the transaction data multi-period variable cycle characteristic can be adapted; the method meets the requirement of constructing the same configuration picture, realizes the associated definition and acquisition of different transaction subject objects or time data, and does not need to re-edit the picture or construct a large number of pictures.
The following detailed description of embodiments of the invention is provided in connection with the accompanying drawings.
The invention provides a method for generating a power transaction data graph, the flow of which is shown in figure 1, and the method comprises the following steps:
loading a graphic file; setting a data source associated with a graphic element of the graphic file by using data source parameters; the data source parameters are specified by an external parameter file and are related to the electric power transaction scene;
and acquiring data corresponding to the data source in the graph file to generate a power transaction graph.
More specifically: local data source definition: when the graph is drawn, the data of partial graphic elements can be directly obtained through a local control without sending a data fetching service, and the data source is a local data source. For example, the current time needs to be obtained, which can be directly obtained through the local graphic time control.
System data source definition: the data source which needs to acquire data from the database through the access service becomes the system data source. For example, if the total amount of transactions per month needs to be obtained from the histogram, such data needs to be obtained by accessing the database at the server side.
The method breaks through the original primitive data acquisition mode in data acquisition, divides the data source into a plurality of dimensions when defining the system data source definition, and divides the data source into 3 dimensions, namely a main dimension, an application dimension and a time dimension in the power transaction mode. The three dimensions act together to uniquely determine one data source. The three dimensions are characterized as follows:
the main dimension: the subject dimension is the subject object with which the data is associated. The subject object is a subject of the data source, and can be an electricity selling party or an electricity purchasing party in the electricity transaction.
Application dimension: the so-called application dimension is the behavioral application of the subject object. The behavior application is an expression form of a main object, and can be the trading volume of a power plant or the quotation of trading in trading.
The time dimension is as follows: the so-called time dimension is the time domain acted on by the subject object behavior application. The definition of the time dimension may be a period of time or a fixed point of time.
A schematic diagram of a primitive data arrangement is shown in fig. 2. And a local data source defined by the graphic primitive data is associated to the local control, a main dimension, an application dimension and a time dimension of the system data source are associated to the access service, and data are obtained from the database. The main dimension, the application dimension and the time dimension can also be associated to the local control to realize dynamic association, namely, when the graphic file is edited, display primitive association data can be defined as dynamic definition, and when the data needs to be acquired, the data association definition is carried out through dynamic selection. For example, the subject dimension is associated to a drop-down list, and the subject dimension component in the data graph association to be displayed is controlled through the drop-down list.
The data source associated with the graphic element in the graphic file can be set through an external parameter file. The external parameter file specifies data source parameters related to the electric power transaction scene, and the data source associated with the graphic element is set by the data source parameters. When the data source needs to be changed, the data source related to the graphic element can be changed to the needed data source by modifying the external parameter file, and the data source related to the graphic element can be changed without modifying the graphic file per se, so that the graphic is flexibly displayed.
And the system data source association definition is dynamically analyzed according to user operation or external parameter files during graphic operation, so that the flexibility of graphic display is enhanced.
The graphic data loading flow diagram is shown in FIG. 3 and includes
Loading a graphic file;
judging whether the data is a local data source or not, and if so, acquiring and displaying local data control data; otherwise, turning to the next step;
obtaining the main dimension configuration, judging whether the main dimension configuration is dynamic data or not, and if so, obtaining the local control parameter and turning to the next step; otherwise, directly turning to the next step;
acquiring application dimension configuration, judging whether the application dimension configuration is dynamic data, and if the application dimension configuration is dynamic data, acquiring local control parameters and turning to the next step; otherwise, directly turning to the next step;
acquiring time dimension configuration, judging whether the time dimension configuration is dynamic data, and if so, acquiring local control parameters and turning to the next step; otherwise, directly turning to the next step;
forming system data source parameters;
acquiring data from a database through a graph access service;
and (6) displaying the graph.
The following illustrates an embodiment of a data multidimensional definition and association method in a power trading scenario.
When a primitive < DataString > is configured, a data source needs to be distinguished, and the primitive needs to acquire two types of data, time data and transaction total data. The two types of data are different in that time data can be acquired locally, and transaction data must be acquired from a database, so that the two types of data are acquired in different defined data source formats. Time data is acquired, and a parameter local _ data is required to be configured in the metafile, which indicates that the data source will acquire local data and associate it to the local time control < Date _ time >. When the transaction amount is obtained, a system data source parameter sys _ data needs to be configured, and the parameter indicates that the dynamic data is to be obtained from the database.
And when the primitive is required to acquire data, determining specific dimensional components to determine the data source-related definition. For example, in the power trading scenario, the respective monthly transaction prices of a certain electricity selling party a and a certain electricity consuming party B in the last 5 years need to be presented in the histogram. The traditional configuration graph needs to create 2*5 total 10 graph files, but in the method of the invention, only one graph file needs to be configured, the data dimension parameters of the graph file are dynamically configured, and different dimension components of the graph file are related to the local control.
And loading the local control. Many primitives in the graph need to be associated with local controls, and thus the local controls need to be configured before these primitives are configured. Such as a configuration time control and an object selection control such as a body drop down menu.
And (5) configuring the columnar graphic elements. When configuring the histogram < bar >, the system data source sys _ data tag needs to be configured in addition to the basic attribute. The dynamic data dimension application dimension < app _ data _ bind >, the time dimension < time _ data _ bind > and the body dimension < phy _ data _ bind > need to be configured in sys _ data, and the body dimension is associated to a local object selection control, the time dimension is associated to a time control, and the application dimension is associated to a transaction price application scene. In the primitive configuration, the data source association definition of the primitive is not solidified, and the data source association definition of the primitive can be switched according to the operation of a control on the same screen by a user at any time.
A data source is determined. When a user browses a screen, the user operates the time control, the time control selects a certain year, the object selection control selects an electricity selling party or an electricity using party, for example, determination 1 and determination 3 in fig. 2 are performed, after determination 1, determination 2 and determination 3 are performed, a main body dimension, an application dimension and a time dimension are all determined uniquely, a system data source can be determined uniquely at this time, and a data association definition access request is sent to the access service.
