DataPreprocessing Enhancements

[pfleck]

This ticket contains smaller visual enhancements of the preprocessing views.

This ticket depends on #2713.
To avoid losing features, #2715 should be released previously to this ticket.

Enhancements

• ViewHost/ViewShortcut usage
  • Remove ViewHost icons for the ViewShortcuts
    • Split Single- and Multi-Scatterplot
  • Remove “View Shortcuts” grouping box
  • Doubleclick a ViewShortcut should not reset the state in the new view
• PreprocessingCheckedItemView
  • Hide Move, Add, Delete buttons
  • Add Select Input/Target, All and None as Buttons (checkboxes with tooltips)
    • Remove context menu instead
• DataGrid + Statistics
  • Show/Hide columns and rows
    • Check All, Input/Target, None Variables option
• DataCompletnessChart
  • Remove title
  • Move legend to top (column style)
• Scatterplot
  • Better default axis ranges (Bogdans helper functions)
  • Axis description instead of legend
  • Manual axis-range (also for linechart) (currently via config dialog)
• MultiScatterplot
  • X-axis labels vertical
• Better placement for statistics summary in statistics view

New features

• Distinguish Color and Grouping option in scatterplot
  • Current “Color” feature becomes “Grouping”

  • If Group is selected and no Color is selected, also select the Color for this feature
• Scatterplot
  • Add slider for changing point size (currently via config dialog)
  • Add regression line and add option to show/hide (implemented in #2713)
• MultiScatterplot
  • Add (better) tooltips
    • Add correlation coefficient to scatterplot
    • Add name to histogram
• Histogram + MultiLinechart
  • Add chart size sliders (as in MultiScatterplot)
    • or column count?
