[opendx-users] How to exclude part of data

[Jonathan Matheson]

I am importing 2 3D dx files into my .net program. One of them contains pressure values in the ‘data’ field. The other shape file has only ‘positions’ and triangular  ‘connections’ fields with no data. The pressure values within the shape are garbage and I need to make my program ignore them. The problem is that outside of the shape the pressures are all pretty close but inside they are really high and really low. As a result of this my colour map does not show the pressure differences outside the shape. I can manually set the max and min values through the ‘include’ function but dx is automatically called from another program and that is not an option. I am looking for a way to search for the max and min pressure values while ignoring those that are inside the shape. If I could do that I can set those values in the ‘include’ function and everything will display properly.   Thanks, Jon
