Hi all,
I have the following code.
cb = colorbar();
set(cb, 'ylim', [0.1 10])
cb.Ticks = [0.1 1 10];
cb.Ruler.Scale = 'log';
cb.Ruler.MinorTick = 'on';
.
.
.
scatter(particle1_newlng,particle1_newlat, 10, V_curr, 'filled');
I am trying to change the color of the x and y coordinates based on the velocity input (V_curr). This scale is a log scale from 0.1 to 10 for the colorbar.
However when I run the above code the colors do not fade evenly over the entire scale (see picture). Any ideas on how to fix this??

You should be using
doc caxis
to change colourmap limits, not directly going into the colourbar object and changing its ylims. This will literally just change the ylims of the colourbar and will have no effect on the underlying colourmap itself.
