based on this example I created a rendering of some data as a parallel coordinates plot using the vtkParallelCoordinatesView. In a different plot where I plot a point cloud I was able to set the color for each point individually by setting a lookup table and selecting a color array. I was using a vtkPlotPoints together with a vtkChartXY and a vtkContextView there so the setup there is a little bit different.
I was wondering if there was something similar for vtkParallelCoordinatesView such that I am able to color lines based on some scalar value? This is an example from wikipedia showing what I am trying to achieve.
Also I am a little bit confused why there is two possible ways to setup a parallel coordinates plot:
They both share base classes (vtkRenderViewBase I believe) but differ in the way you set them up and their API. I decided to go with the first one since that seems to have better support for interacting with the plot which is something that I need.
