f61b46b96b NEW: secondary axes: added functionality to manage additional secondary axes in a JKQTPBasePlotter and to select which x-/y-Axis to use for drawing a JKQTPPlotElement, see also issue #87 2023-03-23 13:55:18 +01:00

03031e3762 JKQTPlotter: 
- NEW: improved plotting speed for line-graphs by a compression algorithm (see JKQTPGraphLinesCompressionMixin) that removes overlaying lines (e.g. in JKQTPXYLineGraph)
    - NEW: improved plotting speed for line-graphs by a clipping algorithm (applies to JKQTPXYLineGraph, JKQTPGraphErrorStyleMixin, JKQTPSpecialLineHorizontalGraph, JKQTPSpecialLineVerticalGraph and others)
    - NEW: improved plotting speed for scatter-graphs by not calling draw functions for symbols outside the plot window (e.g. in JKQTPXYLineGraph)

4347d27c04 * reworked color-palette-system: 
1. added several new (JKQTPMathImageBone, JKQTPMathImageCool, JKQTPMathImageCopper, JKQTPMathImageAutumn, JKQTPMathImageSeismic, JKQTPMathImageTerrain, JKQTPMathImageViridis, JKQTPMathImageMagma, JKQTPMathImageInferno, JKQTPMathImagePlasma)
  2. reworked LUT-types (now a QVector, instead of a C-array, suing malloc)
  3. reworked available functions to build LUTs (cleanup, more options, clearer names)
  4. added functions to load palettes from files
  5. Improved documentation
* added example for user-controlled color palettes
