hi Excel masters,

Could you help me to find the solution on this problem:

I have item A & B, which I want to make a table that will auto compute how long will item A & B will last, given the usage rate per quarter.
And at the same time it will plot the bar graph of which X-axis is the months and Y-axis is item A & B.

Item Usage/quarter months depleted
A ? Jan / Feb / Mar .......
B ? Jan / Feb / Mar .......
