Greetings dear friends, I am trying to plot a bar chart for a set of twelve data in x and twelve data in y, but I think I am making a mistake in the use of some command, I appreciate your help:
This is my interface with each name:
This is my code:
x=[6,12,20,30,40,50,70,100,140,200,270,300];
y13=str2double(app.EditField_12.Value);
y14=str2double(app.EditField_13.Value);
y15=str2double(app.EditField_14.Value);
y16=str2double(app.EditField_15.Value);
y17=str2double(app.EditField_16.Value);
y18=str2double(app.EditField_17.Value);
y19=str2double(app.EditField_18.Value);
y20=str2double(app.EditField_19.Value);
y21=str2double(app.EditField_20.Value);
y22=str2double(app.EditField_21.Value);
y23=str2double(app.EditField_22.Value);
y24=str2double(app.EditField_23.Value);
y=[y13,y14,y15,y16,y17,y18,y19,y20,y21,y22,y23,y24];
%ref=sum(y)
%axes(app.histo);
bar(app.histo,x,y,1,'histc')
grid on
And I get this (for certain y-values):
Thank you very much for your help!

bar(app.histo,x,y)
Try only using the above arguments. I think you want some histogram to be plotted , in that case use histogram function instead of bar

Ok. You can use the app function handle like you did before. And also add the xticklabels command as i shown.
For demonstration purposes i have commented it. Can you share the app code

This is my code dear friend, but it does not work:
x=[6,12,20,30,40,50,70,100,140,200,270,300];
y13=str2double(app.EditField_12.Value);
y14=str2double(app.EditField_13.Value);
y15=str2double(app.EditField_14.Value);
y16=str2double(app.EditField_15.Value);
y17=str2double(app.EditField_16.Value);
y18=str2double(app.EditField_17.Value);
y19=str2double(app.EditField_18.Value);
y20=str2double(app.EditField_19.Value);
y21=str2double(app.EditField_20.Value);
y22=str2double(app.EditField_21.Value);
y23=str2double(app.EditField_22.Value);
y24=str2double(app.EditField_23.Value);
y=[y13,y14,y15,y16,y17,y18,y19,y20,y21,y22,y23,y24];
%ref=sum(y)
%axes(app.histo);
bar(app.histo,x,y,1,'histc')
grid on
It should be noted that:
1. The values of x are fixed
2. The values of y13 to y24 are percentages.
3. The histogram in the matlab app designer interface is called app.histo (the histogram or bar chart should appear in this graphical interface).
