Embodiment 1

[0037] Such as figure 1 As shown, the present invention provides a sequence data pixel visualization adaptive visual mapping adjustment method, the adjustment method includes:

[0038] S100. According to the preset mapping method, perform pixel visualization on the screen according to the global visual mapping for multiple pieces of sequence data input by the user, each sequence includes multiple data points, and each data point corresponds to a pixel;

[0039] Preset mapping methods include:

[0040] Maps the value of a data point to the color or area of ​​the corresponding pixel.

[0041] Map the position of the data point in the current sequence to the abscissa of the corresponding pixel on the screen;

[0042] Map a single sequence of data to a row of pixels;

[0043] Map multiple pieces of sequence data into vertically juxtaposed rows of pixels.

[0044] Such as figure 2 As shown in , each square represents a pixel, each pixel corresponds to a data point, and the ar...

Embodiment 2

[0055] The present invention provides an adaptive visual mapping adjustment system for sequence data pixel visualization, and the adjustment system includes:

[0056] The mapping module is used to perform pixel visualization on the screen according to the global visual mapping of multiple sequences of data input by the user according to a preset mapping method, each sequence includes multiple data points, and each data point corresponds to a pixel;

[0057] Preset mapping methods include:

[0058] Maps the value of a data point to the color or area of ​​the corresponding pixel.

Abstract

The invention discloses a sequence data pixel visualization adaptive visual mapping adjustment method and system. The adjusting method comprises the steps of S100, conducting pixel visualization on multiple pieces of sequence data input by a user on a screen according to a preset mapping method and global vision mapping, wherein each sequence comprises multiple data points, and each data point corresponds to one pixel; S200, according to the size of the screen, setting a display area of the plurality of pieces of sequence data on the screen; and S300, after it is determined that the user selects a part of the display area on the screen, calculating a mapping range of the part of the display area, and adjusting global visual mapping including the part of the display area according to the mapping range. According to the invention, the visual mapping in the pixel visualization is automatically adjusted according to the mapping range of the partial display area selected by the user, so that the pixel visualization can better display the local features of the high dynamic range data.

Description

technical field [0001] The present invention relates to the field of information visualization, in particular to a sequence data pixel visualization adaptive visual mapping adjustment method and system. Background technique [0002] Time series data exists widely. In many cases, it is necessary to visualize multiple time series data in order to compare these data. In this case, pixel visualization for time series data is proposed. Unlike traditional line charts, the display space of each sequence in pixel visualization is independent, using the visual attributes of pixels (squares) (such as color, area, etc.) represents each data point of each series. Traditional pixel visualization adopts a unified visual map for data. When the data range is large, it is difficult to reflect the small local differences in the data. Contents of the invention [0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide a sequential data pix...
