Hello,<br><br>I have implemented vector plot for unstructured grid.. Now i want to display a legend showing the min arrow size and max arrow size along with the min and max vector magnitude..<br><br>To put a legend i made use of vtkLegendBoxActor as shown in the following example<br><br>http://www.vtk.org/Wiki/VTK/Examples/Legend<br><br>But am failing to display an arrow with two different sizes. i.e. a small arrow and a big arrow. Following <br>is the code i used<br><br>vtkSmartPointer<vtkArrowSource> bigArrow = vtkSmartPointer<vtkArrowSource>::New();<br><br>vtkSmartPointer<vtkPolyData> bigArrowPoly = bigArrow->GetOutput();<br><br>similarly one more set of arrow source and polydata I have declared and added to the renderer..<br><br>I am getting two arrows, but how do i change the size of these arrows..??<br><br>Thanks in Advance<br>Rakesh Patil<br><br><br><br><div style="border-top:1px dashed #ccc; border-bottom:1px dashed #ccc; padding:5px;"><a href="ht
