[vtkusers] about points in vtkXYPlotActor

[Miguel Angel Chavez Alfonso]

Hello people.	
I am a Cuban student and I'm working with VTK. I need to graph the X and the Y grids in a vtkXYPlotActor figure but I don't found nothin about it in VTK. I attach 4 images that explain what i want to do. I graph the figure but I dont graph the X and the Y grids. write me if you've seen something about it or if you have any idea or any examples.
I was searching how draw 2 points in 2D with vtkXYPlotActor or a dashed lines but I don´t find nothing.


PD: the images attached were made in another program not with my program.
I don't speak English very good I speak Spanish excuse the mistakes.
thanks.
