Berthold Stoeger	b5aac29cea	statistics: collect colors in a StatsTheme class ... To enable rudimentary theming, collect all colors in a new theme class. The class has to be passed down to the various items. In general the items save a reference to the them in the constructor. Alternatively, they might also just query the StatsView everytime they need to access a color. For now, it's hard the say what is preferred: a reference per item or a function call per invokation?

Berthold Stoeger	ba259fb1d6	statistics: make confidence area and regression line opt-in ... This is not perfect - the polygon of the confidence area is calculated even if it is not shown. Oh well. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>	2021-01-20 08:47:18 +01:00
Berthold Stoeger	2008857660	statistics: render regression item using QSGNode ... Render the confidence area and the regression line into a pixmap and show that using a QSGNode. It is unclear whether it is preferred to do it this way or to triangulate the confidence area into triangles to be drawn by the shader.
