Hi All!,  
If I try to display a very large 2D matrix in Matplotlib, performance will degrade, especially the mouse interactions will become really slow. Does ParaView support parallel rendering (MPI and/or GPUs) in any of its 2D views (let’s say **ImageChartView** ) to improve performance for large 2D data?

Is your question specific to ImageChartView or to all charts in ParaView ?

Yes, could you please comment about **ImageChartView**. If that view does not support parallel rendering, do you know if any other 2D views has the support? Thanks in advance!

To my knowledge, none of the 2D views support parallel rendering.

Good to know. Don’t know if mine is a stupid plan but this forces me to think of writing a new “View” plugin in C++ that incorporates the QtWebEngine to render a web page. With a web context, I hope to use the parallel rendering capabilities of pipelines like datashader ([https://datashader.org/](https://datashader.org/))  
@cory.quammen What do you think?  
I want to promote the idea of developing custom applications by reusing/extending the paraview architecture, which is why I am thinking of having views inside ParaView.
