How to plot more data than categories

Does anybody know how can I plot in same bar plot more than 2 files of categorical data if I only have 2 categories? For example, if I have:

data=[1 2
      2 1
      1 3]
X_cat=categorical({'Case1','Case2'})

How to get bar(data,'grouped')?

Thanks in advance!

Sorry, I don't follow what you expect to happen here... :)

Can you show a sketch or describe what you think the bar plot should look like?

ADDENDUM (MUCH LATER)

Or maybe the data are just oriented incorrectly and what is intended is

bar(X_cat,data.','grouped')

??? which yields

Yes! It was just that. Sorry if I did not explained properly before.

Thank you so much!

bar(y) creates a bar graph with one bar for each element in y. If y is a matrix, then bar groups the bars according to the rows in y.

Here, in your case, data is oriented incorrectly - need to give transpose of data (i.e., data') as input to the bar() function.

The following code would help you solving this problem.

data=[1 2
      2 1
      1 3]
X_cat=categorical({'Case1','Case2'})
bar(X_cat,data','grouped')
