Exclamation A newbie to Contour Color Plots

contour is on a distinguished road

I have conducted an experiment in obtaining the horizontal and vertical airflow velocity for a pitot tube. Results have been taken in increments of 5Hz to 40Hz. The pitot tube has been inserted at 6 different sampling distances (both horizontally and vertically).

My question:

Using the sampling distances and velocities obtained at different frequencies, how do I represent the airflow using a contour color plot?

I have GNUPLOT and Originlab available and only intend on using one of these packages.

Thank you.
p.s: I hope this is in the correct thread, apologies if not.

you'll create a matrix with your velocities in each of the cells. Then, plot the matrix as a contour plot. There is usually an option for that.
