Advanced 3-D bar plot

Hello,

I have measurements that are conducted on a rail that has a cross-like shape (please see attachment 'Measuring positions.png). I repeated the measurements 3 times, so I have 3 time series for each position. Next, I determined the number of zeros in each time series and now I want to plot it (i.e., number of zeros) as a grouped bar for each position. Namely, the graph should look like my attachment 'Advanced bar.png'.

I tried using bar3, but it does not give me that cross-like displacement of bars.

Any suggestions?

Thanks,

Djordje
