jkriege2	ebf034710b	bugfix: parsed functions did not work properly	2020-09-09 11:45:33 +02:00
jkriege2	ba856b594f	removed/breaking change: removed the overlay elements (derived from JKQTPOverlayElement), which were not very well set up and are more confusing than useful.	2020-09-09 11:26:04 +02:00
jkriege2	95d885bc2c	- bugfix: improved handling of DRAGZOOM-UserAction for log-log plots ... - code (style) improvements	2020-09-08 20:15:33 +02:00
jkriege2	f77bc97ca5	- cleanup of class-hierarchy of evaluated functions ... - added slots for several properties of evaluated functions - updated examples	2020-09-07 20:58:20 +02:00
jkriege2	414e12920e	- added further base-class JKQTPEvaluatedFunctionWithParamsGraphBase, which extends JKQTPEvaluatedFunctionGraphBase with parameters ... - modified plot-function with parameters, as the old unsafe way of giving a void* for parameters is no longer necessary with C++-lambdas and std::bind()	2020-09-05 13:47:46 +02:00
jkriege2	dcdee469fe	rename JKQTPFunctionLineGraphBase -> JKQTPEvaluatedFunctionGraphBase	2020-09-05 13:16:26 +02:00

jkriege2	8c0c8bf62e	simplification/unification: JKQTPXFunctionLineGraph and JKQTPYFunctionLineGraph now use JKQTPAdaptiveFunctionGraphEvaluator to generate sample points	2020-09-05 12:44:02 +02:00
jkriege2	c57c672f78	new: a new graph class JKQTPXYFunctionLineGraph draws parametric 2D curves (f(t) -> [x,y])	2020-09-04 23:47:03 +02:00
jkriege2	33a9cb5b2d	bugfix: straight lines in pie and chord were not drawn as curve in DrawMode=DrawAsMathematicalCurve	2020-09-03 23:28:48 +02:00
jkriege2	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	2020-09-03 23:08:52 +02:00
