How to plot z component as a colorbar with lines connecting scatter plot points?

39 Ansichten (letzte 30 Tage)
I have a data set with x, y and z scalar components. I am trying to make an x vs y plot with z shown as a colorbar. My current code does this however, I need it to connect all the points with a line and that line should be a colorbar. I tried adding line(x,y) to the plotting code but this adds just a line without a color scale. How do I add a line to connect (x,y) points that is a colorbar of z?
c = colorbar;
c.Label.String = 'z';
