MATLAB: Scatter Plot with string in x-axis and integer on y-axis

Question

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?

Answer 1

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];
