aa2fcb108d NEW/REWORKED JKQTBasePlottercan be used is re-entrant, i.e. different instances can be used from different threads in parallel (although there is significant overhead due to shared caches between the threads!).

99ff39a3d6 FIXED issue mentioned in https://github.com/jkriege2/JKQtPlotter/pull/110: Lock the panning action to certain values: View zooms in, when panning close to AbosluteXY</a> (thanks to https://github.com/sim186 for reporting) 2023-12-21 15:10:20 +01:00

995ca92033 FIXED/REWORKED issue https://github.com/jkriege2/JKQtPlotter/issues/111 : Can't write to PDF files with JKQTPlotter::saveImage() when passing a filename ending in ".pdf" (thanks to https://github.com/fpalazzolo for reporting)
IMPROVED/REWORKED: The functions JKQTBasePlotter::saveImage(), JKQTBasePlotter::saveAsPixelImage(), JKQTBasePlotter::saveAsPDF(), JKQTBasePlotter::saveSVG(), ... gained a bool return value to indicate whether sacing was successful.
IMPROVED/REWORKED: More <code>save...()</code> functions will appear in the API of JKQTPlotter, so you don't have to go via JKQTPlotter::getPlotter(). These are merely forwarding the call to the internel JKQTBasePlotter instance.
