Detailed Description

This Mix-In class provides setter/getter methods, storage and other facilities for a line-graph compression algorithm.

supported properties:

activate compression (improves plotting speed, but decreases detail level)
level of retained details

this sets the agressiveness of the option useNonvisibleLineCompression

Basically the compressed groups will have a size of nonvisibleLineCompressionAgressiveness*pen.linewidth

The default setting is 1.0 , larger settings will lead to better compression (and faster plotting), but less detailed plots, whereas smaller settings will increase the detail-level, but also increase plotting time.

Note: This option is designed to not alter the plot representation significantly, but of course it may ...

bool JKQTPGraphLinesCompressionMixin::m_useNonvisibleLineCompression

private

use an optimization algorithm that tries to reduce the number of lines that overlap each other (i.e. for noisy data or a low zoom) and thus improves drawing speed

When the property useNonvisibleLineCompression is activated (true ), the graph class uses the algorithm implemented in JKQTPSimplifyPolyLines() to simplify the task of plotting.

Note: This option is designed to not alter the plot representation significantly, but of course it may ...
