Plotting a standardized histogram in MINITAB

Hi! Hope you guys can help me with this one:
I'm trying to plot a standardized histogram using MINITAB. The x axis must show -3SD, -2SD, -1SD, 0, +1SD, +2SD, +3SD as bins. Is there a quick, easy way to do that?
Thanks a lot!
First click on calc -> standardize to standardize your data. Then plot your data using Histogram. Double click on the x-axis -> scale -> positions of ticks-> enter -3:3/1 -> OK

Hope it helps.
