Superb,
That was it. Thanks, both of you.
But I have another question.
The automatic scaling of the vector field works as expected.
The scaling of the temperature however does not(array of floats). It set
the range to [0 1], regardless of the actual values.
Paraview(under information) gives the data range = [3.5 1333.5], which is
correct. And if I manually set the color range to this, everything is good.
Pressing the automatic color scale(rescale to data), the used interval is
set back to [0 1].
Why is that?
I use to code suggested by Joe,
vtkFloatArray* temperature = vtkFloatArray::New();
temperature->SetName("Temperature");
temperature->SetNumberOfComponents(1);
temperature->SetNumberOfValues(mesh.nn);
for(int i=0;i<mesh.nn;i++){
temperature->SetValue(i,3.5);
}
rgrid->GetPointData()->AddArray(temperature);
And is it possible to update the plot if I overwrite the .vtr file, without
closing and reopening the file?
Paw
