How do I create a stacked chart with 3 variables?

What I have is ex: duration to make a pizza.

I have 4 months that i need to be displayed in one long chart.

Vertical Info: Time from phone call to chef, chef to topings, topics to oven, oven to delivery.
Horizontal Info: Store 1, store 2, store 3, store 4, store 5.

So what i need is a stacked chart that shows the data for each month.. so have 5 bars close to each other for the AUG, 5 bars close to each other for JULY and so on.. with dates Y axis and months as X axis.

Help please!

Thanks
