4f73fbbaed JKQTPlottter: added the option to draw a character from a font as symbol (JKQTPCharacterSymbol+QChar('').unicode()) 2022-09-02 14:19:47 +02:00

74d54abac5 JKQTCommon: refactoring of JKQTPPlotSymbol(): using static datastructures to store precalculated drawing instructions (polygons, QPainterPath, ...), this should improve the drawing speed a bit and makes the code less complex 2022-09-02 12:27:12 +02:00

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)

279ef7880a - improved: geometric objects now use an adaptive drawing algorithm to represent curves (before e.g. ellipses were always separated into a fixed number of line-segments)
- improved: constructors and access functions for several geometric objects (e.g. more constructors, additional functions to retrieve parameters in diferent forms, iterators for polygons, ...)
- new: all geometric objects can either be drawn as graphic element (i.e. lines are straight line, even on non-linear axes), or as mathematical curve (i.e. on non-linear axes, lines become the appropriate curve representing the linear function, connecting the given start/end-points). The only exceptions are ellipses (and the derived arcs,pies,chords), which are always drawn as mathematical curves
