I want to do a 2D plot based on 3 columns of data (X,Y and Z) . X column show positions, y column show speed and z column show emissions. I guess first I should make meshgrid between x and y then show the z values on this 2D plot. I want to have a result like the bottom of this image. So the result will shows emissions as colors on x(position)-y(speed) axis. Can somebody help me about this?
