Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] Such as figure 1 The illustrated embodiment is a dynamic multi-level histogram display method for hierarchical data. The display screen of this embodiment has WIDTH=1260 pixels and HEIGHT=696 pixels, such as figure 2 As shown, the second layer of nodes includes the nodes analytics, animate, data, display, flex, physics, query, scale, util, and vis, as well as the nodes of the third and fourth layers.

[0046] Such as figure 1 shown, including the following steps:

[0047] Step 1, sort all nodes in descending order of quantized attribute values. Sort the results in descending order as follows: analytics, animate, data, display, flex, physics, query, scale, util, vis.

[0048] Step 2, divide all nodes in the second layer into two arrays: array A and array B. Array A contains analytics, array B contains animate, data and all other nod...

Abstract

The invention discloses a dynamic multi-stage histogram display method of layering data. The dynamic multi-stage histogram display method is a context-based layering layout algorithm, the layering data are better expressed by exploring a length-width ratio of a rectangle of an array, efficient and rapid drawing of a histogram on a mobile platform can be achieved, and a dynamic multi-stage histogram can be displayed to the layering data.

Description

technical field [0001] The invention relates to the technical field of hierarchical data, in particular to a dynamic multi-level histogram display method capable of efficiently and rapidly drawing hierarchical data of a histogram on a mobile platform. Background technique [0002] As a visual display method of spatially hierarchical data, the tree diagram can make full use of the display space to present large-scale hierarchical data, and emphatically express the quantitative attributes and distribution relationships of data nodes through the size and position of its nodes. [0003] The treemap layout algorithm is the core content of the treemap visualization method, which is used to draw visual graphics on a two-dimensional plane according to the hierarchical structure, node weight and node sequence of the treemap of hierarchical data. [0004] However, due to the recursive nature of the tree graph layout algorithm, it cannot be used for dynamic display of hierarchical data...
