hi all
sorry to disturb again
as my previous thread, my simulation is to check the velocity profile of air in the pipeline.
so, i make a line at the end of pipe, and obtain the graph of velocity profile.
something like this

then, i plot the graph where that line is use as a reference, like this

the problem is, since my origin on geometry is at centre of pipe, so the graph scale turn to be like that. (positive and negative value)

is there a way for me to change the scale for Y axis so it would turn to positive value only?
