Description

Some currently running projects will require plotting capability which is not available in QmitkPlotWidget at this time.

Needed features I am aware of:

  • Possibility to add (asymmetric) x- or y-errorbars
  • Setting the legend attribute (how the legend is drawn for a curve (line, symbol...))

Nice to have features I am aware of:

  • Drawing vertical lines (For marking a specific x value, such as a maximum)
  • Highlighting one point as "selected" (e.g. the point corresponding to the currently selected timestep)

Features that would need to be discussed:

  • Should it be possible to get the data vectores back? Or should any exporting be done by the view feeding the data to the plot widget. E.g. for copying to clipboard

The current (as of 1870e766c264eaa3bf128fd36a0e80c1c39eddf9) implementation allows adding of x- and y-errorbars and setting the legend attribute.

It would be possible to add functions for adding vertical/horizontal lines to the interface. This can be achieved using the QwtPlotMarker class. However, I do not think this will add a real benefit vs accessing the QwtPlot directly.

While we know that a curve has associated error curves, and can manage them accordingly (and together), this would not be true for a marker.
