My data is
samples=["4S1";"4S2";"4S3";"4S4";"4S5"]';
percentage=[0;-11.5000000000000;-2.44000000000000;-8.13000000000000;-2.44000000000000]';
scatter(samples,percentage);
Error Message:
Error using scatter (line 56)
Input arguments must be numeric, datetime, duration or categorical.
Can anyone please help?

I tried with the code, no error in my case. But the question is obvious, samples is strings, how you are going to plot with non numeric variables? Are you looking for Bar Plot?
Thank you KALYAN ACHARJYA for your answer, however, please check my answer that I posted recently. Have a good day. Thank you once again :)

I had found myself recently, actually as mentioned in the error, it should be categorical,
Here is the program,
n=["4S1";"4S2";"4S3";"4S4";"4S5"]';
y=[0;-11.5000000000000;-2.44000000000000;-8.13000000000000;-2.44000000000000]';
x=categorical(n);
s=scatter(x,y);
and if you want your graph to look nice, use the following,
s.LineWidth = 0.6;
s.MarkerEdgeColor = 'b';
s.MarkerFaceColor = [0 0.5 0.5];

Maybe bar chart would be better for you, but if you must use scatter plot
scatter(1:5,percentage);
set(gca, 'XTick', 1:5, 'XTickLabel', samples);

One more thing, when you need to plot something but don't know how, its always a good idea to check the plot gallery
