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 yieldsuntitled.jpg

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')
For more information on plotting bar graphs, refer to the following link:
