How to plot string on X-axes and number in Y-axes in figure?

Hello,

I want plot my RMSE data value on the y-axes and the string the value on the x-axes for my research work paper.

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)
set(gca,'xticklabel',x_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'}

But plot is not defined for either string or cellstr variables. You could instead convert that text data to categorical and make a categorical plot.

C = categorical(x_axes1)

C = 1×4 categorical array
     Case-1      Case-2      Case-3      Case-4 

plot(C, (1:4).^2, 'ko-')

Thank you so much for your time.

But Case-1 is going away from the starting point of x-axes. How can I bring it on the begining of the x-axes? And also, how can I make case-4 as the last point?

 % if true
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)
set(gca,'xticklabel',x_axes.');
xticks(1:4)

Try this

Thank you so much. It works with my code :)
