Hello,

I need to set legend also. I tried following code but its not working

Following is the sample code

x_axes=['Case-1','Case-2','Case-3','Case-4']
Y_axes=[4,5,6,7]
figure('name','sample','PaperSize',[3.3 2.71],'NumberTitle','off');
plot(Y_axes)

This doesn't do what you think it does.

x_axes=['Case-1','Case-2','Case-3','Case-4']
x_axes = 'Case-1Case-2Case-3Case-4'

Instead use a string array or a cell array each element of which is a char vector.

x_axes1=["Case-1","Case-2","Case-3","Case-4"]
x_axes1 = 1×4 string array
    "Case-1"    "Case-2"    "Case-3"    "Case-4"
x_axes2={'Case-1','Case-2','Case-3','Case-4'}
x_axes2 = 1x4 cell array
    {'Case-1'}    {'Case-2'}    {'Case-3'}    {'Case-4'}
