i resolve it by adding  
#include “vtkAutoInit.h”  
VTK\_MODULE\_INIT(vtkRenderingOpenGL2); // VTK was built withvtkRenderingOpenGL2  
VTK\_MODULE\_INIT(vtkInteractionStyle);  
VTK\_MODULE\_INIT(vtkRenderingVolumeOpenGL2);

#pragma warning(disable : 4996)  
before main function  
but i have new error  
“vtkContextDevice2D”  
how to resolve new error ??

Hi @dp1991 -

That topic would be better for the VTK discourse:

> **[VTK](https://discourse.vtk.org/)**
>
> A place to discuss VTK development

Note that you can display plots (line, bar, scatter) in Slicer from Table nodes using Plots module. You can also create a plot from Python as shown in [this example](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Plotting).
