How can I plot my data from the same group according to the color bar? (same group will be same colour)

Ran in:
You can pass in a color for every data point as the fourth input argument to scatter.
Try this:
x = 1:10;
y = 51:60;
cmap = turbo(length(y))
cmap = 10×3
0.1900 0.0718 0.2322 0.2737 0.3835 0.8449 0.2093 0.6654 0.9760 0.1034 0.8960 0.7150 0.4483 0.9959 0.3694 0.7824 0.9376 0.2033 0.9800 0.7300 0.2216 0.9643 0.4186 0.0964 0.7941 0.1660 0.0143 0.4796 0.0158 0.0106
scatter(x, y, 200, cmap, 'filled')
grid on;
colormap(cmap)
colorbar
caxis([min(y), max(y)])

@Astthor Gislason that's too bad, but you didn't give us your code. I ran the code again and it gave me exactly the plot I had posted. You must have changed the code somehow.
If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
