How to change Dose (X-axis) increments on a Dose-Volume-Histogram?

Hello fellow Slicers,

I am currently testing Monte-Carlo simulations on a synthetic lung with a proton beam (all input files are in DICOM) and am trying to output a DVH file. However, since the DVH program seems to only register voxel doses on a 0.1 Gy increment and my max voxel dose is much below that, I end up with a problem : my DVH table simply states that 100% of the selected volume receives at least 0 Gy and 0% of that same volume receives 0.1 Gy.

Is there a way to change the default increments of 0.1 Gy?

Thanks in advance,

Jeremy
