Hi,
I am trying to plot a new SurfacePlot over an existing one clearing it, but what i'm getting it's a strange mixing of the two surfaces. 

SurfacePlot plot = new SurfacePlot;
...
plot->loadFromData(data, poly);
plot->updateData();
plot->updateGL();
...
plot->loadFromData(new_data, new_poly);
plot->updateData();
plot->updateGL();
