f_tot = rand(50,9);
hold on
box on
for ph = 1:length(numhels)
for pr = 1: 1:Nrows(1)
if f_tot(ph,pr) >= 0.85000
c = 'red';
scatter(x(ph,pr),y(ph,pr),9,c,'filled');
hold on;
else
if f_tot(ph,pr) >= 0.7 && f_tot(ph,pr) <= 0.84999
c = 'yellow';
scatter(x(ph,pr),y(ph,pr),9,c,'filled');
hold on;
else
if f_tot(ph,pr) >= 0.6 && f_tot(ph,pr) <= 0.69999
c = 'green';
scatter(x(ph,pr),y(ph,pr),9,c,'filled');
hold on;
else
if f_tot(ph,pr) >= 0.4 && f_tot(ph,pr) <= 0.59999
c = 'cyan';
scatter(x(ph,pr),y(ph,pr),9,c,'filled');
hold on;
else
if f_tot(ph,pr) < 0.40
c = 'blue';
scatter(x(ph,pr),y(ph,pr),9,c,'filled');
hold on;

Hello,
Can the scatter plot be made to take in the colormap or jet function.Instead of the 'c'defining specific colors but rather have the entire points in the plot as a gradient.
Thanks

No loops:
scatter(x(:), y(:), 9, f_tot(:), 'filled');
colormap(jet)
