how to plot bar3 for a data which has 3 columns

I have a data which has three columns. I want to show it on a 3d bar with all the three variables.

I am getting this error "X must be a matrix with two columns".

How would you use your 3 columns to create a histogram?

If you have the counts already, perhaps what you really want is bar3?

You'll hvae to share more details, then. Consider saving your variable to a mat file and attaching it to your post using the paperclip icon. It would also be helfpul if you could describe what data each column contains.
