Problems solved by technology

[0003] There are the following problems in the legend layout of the current GIS system: First, the legend box will cover the GIS system interface, which is not concise enough in the presentation effect of the GIS system interface, and there is a sense of fragmentation; secondly, when the GIS layers that the system needs to access become more and more When there are more, the legend components will become very complicated, and the area occupied by the legend frame in the GIS system interface will become larger and larger, which will seriously affect the system appearance and operation experience; finally, due to the different lengths of the text descriptions of the legends, there will be confusion The typesetting effect in the legend box poses a huge challenge, especially when the layers of the GIS system are dynamically increased or decreased as needed

Embodiment approach

[0090] Obtain the sliding direction and sliding distance of the sliding operation on the current page;

[0091]When the sliding direction is left sliding, the difference between the position subscript before the displacement and the position difference corresponding to the sliding distance is used to obtain the first final subscript. Understandably, the position difference between the sliding distance and each legend of the ring array is the preset It is set, such as sliding 1cm, corresponding to a position difference / displacement;

[0092] When the sliding direction is sliding to the right, the first final subscript is obtained by summing the position subscript before displacement and the position difference corresponding to the sliding distance.

[0093] Replace the legend of the position subscript before the displacement with the legend corresponding to the first final subscript;

[0094] The above-mentioned displacement calculation and replacement operations are performed...

Abstract

The invention discloses a legend display method and device, a storage medium and a terminal, and the method comprises the steps: obtaining a second legend set in a preset annular array, and enabling each second legend to be marked by legend information and the position information of the legend information in the annular array; a first legend set is determined and displayed according to the second legend set, legends in the first legend set are laid and displayed in a legend display frame on the edge line of the current page, and the displayed legend set can be slid; and when any trigger action for the interior of the legend display frame is received, obtaining a display effect corresponding to the trigger action, and displaying the display effect on the current page. According to the method, the representation mode of the annular array is constructed for all the to-be-displayed legend of the current page, and the legend set needing to be displayed is determined and displayed based on the mode, so that all the legends can be displayed in a limited area, and the adaptability of dynamic legend increase and decrease is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a legend display method, device, storage medium and terminal. Background technique [0002] In the GIS (Geographic Information System, geographic information system) system interface, the legend is a very important quick access component, and a legend controls the data access of a GIS layer. Such as figure 1 As shown, in general, a legend box is placed at the lower right of the GIS system interface to store legend components. Each legend component consists of two parts: one is the check box corresponding to the legend, and the other is the text description of the legend. When the check box corresponding to the legend is checked, the data referred to by the legend, such as icons, will be displayed on the GIS interface. [0003] There are the following problems in the legend layout of the current GIS system: First, the legend box will cover the GIS system interface, whi...
