how can I plot scatterplot using scatter or gscatter with different color for each variable

Hi, I am trying to plot some random variables(using gscatter and scatter) with different color

I also tried hsv for triplet RGB color for these functions,but it didn't work

could you please give me an instruction on how can I do that?

n = 200;

dat1=rand(n,1);

dat2=rand(n,1).*0.5;

dat3=-rand(n,1)*0.25;

I'm not completly sure if I fully understand the question.

But the 4th input for the scatter command can be used to indicate the collor.

See the example code below, hope it helps:

n = 200;
dat1 =  rand(n,1);
dat2 =  rand(n,1)*0.50;
dat3 = -rand(n,1)*0.25;

x_data = repmat((1:n)',3,1); % assume some x-data
y_data = [dat1;dat2;dat3]; % gather the y-data

c_data = repelem([1;2;3],n); % generate the color indices

figure
scatter(x_data,y_data,[],c_data,'filled')
grid on
