Sum of month and previous month

[#1]

Hi,

I want to create a chart in which I should have the sales per month. But for example if in January I have $200 sales and in February I have $50 sales. The chart should look like January = $200 and February = $250.

In other words I want to calculate the sum of sales per month with the previous month. Finally on the last month to have the total sales amount.

Jan = $200

Feb = $50

Mar = $100

April = $70

I should have

Jan - 200

Feb - 250

Mar - 350

April - 420

Can anyone give me an idea how to do this ?

Thanks!

You can try the Full Accumulation option also in Expression Tab
