CFD -post particle variable
 

I have been troubled by a question for a long time.
Unlike Fluent which is good at post-processing dpm file, it seems taht CFD-post is not good at doing things like that.
I want to create a Histogram,which has Particle Diameter as its X axis,percentage as its Y Axis. The Particle Diameter is the diameter of the particles coming across a specified area.
In CFD-post,I can only find the averaged particle variable,but that is not what ai want, i want the Particle Diameter data,that is CFD-post can only handle particle field variable analysis ,but i want particle variable analysis.
Does anyone know about this.
I am hoping to concrete help, thanks.
