No there isn't, but it should be relatively straightforward. On your dose image, run vtkContourFilter with isovalues, that evenly split your scalar range into the desired number of bins. Then use vtkMassProperties to compute the area within each dose isocontour and use the charting capability to plot.<br>

Hello VTK users,<br>
<br>
Is there a function to generate Dose Volume Histogram?<br>
<br>
A Dose Volume Histogram is, in essence, a histogram of the area vs. intensity within an arbitrary contour i.e. the contour points are not always at pixel center.<br>
<br>
Thanks!<br><br>Xiaofeng Z<br><br><br> </div>
