Description

  • If size of the detector is large (e.g. 300x300) dragging of color bar to adjust intensity range leads to very slow update of intensity plot
  • It's not clear whether it is due to poor performance of QCustomPlot or our signals are flying too much
One have too
  • Study performance of bare QCustomPlot
  • Analyze with MacOS Insturments/Performance, where the program spends most of the time
  • Revise AwesomePropertyEditor::slotValueChanged, it seems that additional signal blocking is necessary
  • Disable activity of HorizontalSlicePlot and VerticalSliePlot: when they are hidden, they should not react on updates in color bar
Take care also
  • Status string should show an amplitude in scientific notation
Optimize also Projections drawing
  • Projections update is slow when there is a Simulation running
