Hello everyone,
I’m currently building some 2D data visualization tools based on the vtkChartXY and vtkChartMatrix classes. I’ve started by looking at these two examples:
- https://lorensen.github.io/VTKExamples/site/Cxx/Plotting/ChartMatrix/
- https://lorensen.github.io/VTKExamples/site/Cxx/Plotting/ScatterPlot/
What I’m trying to achieve now is to rotate by 90 degrees one of the four charts in the chart matrix.
By looking at the classes documentation I was not able to find a straightforward way to do so.
I found this thread (https://vtkusers.public.kitware.narkive.com/AcvHUjqH/vtkchartxy-rotate-or-flip-a-2d-chart), where the issue seems to have been solved, but I was not able to reproduce those results, nor embed them in the vtkChartMatrix. I am currently using VTK version 8.2.0.
A graphical example of what my final goal is can be found in this image, which is a raster plot with frequency histograms on both the axes.
Thank you very much for any help 
Marco
