As I wrote, qtcharts cannot use OpenGL ES, only OpenGL. True way is switch qtcharts to use OpenGL ES, but now qtcharts from git supports no OpenGL mode, but when I configure my Qt6 from git with -opengl es2 flag, qtcharts wants OpenGL.
The stupid way is if there is opengl es2 flag so in charts.pro and DEFINES += QT_NO_OPENGL
So no more OpenGL in qtcharts. But it is not all.
In qxymodelmapper in QXYModelMapperPrivate::valueFromModel code
error no matching conversion for functional-style cast from QDate to QDateTime
Also this is qxyseries.h
error cast member cannon be redeclared
And there are a lot of warnings in qtcharts from clang.
P.S. Please do qtcharts with LGPL.
