2021-01-20statistics: move colors to statscolors.hGravatar Berthold Stoeger
Most colors were already collected there, but a few were dispersed throughout the source files. For future themeability, move the remaining colors to this common place. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-20statistics: make confidence area and regression line opt-inGravatar Berthold Stoeger
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>
2021-01-20statistics: render regression item using QSGNodeGravatar Berthold Stoeger
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. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
