When using column, bar or line chart widgets in Whatagraph reports, you now have the option to display cumulative data.
The difference between cumulative and non-cumulative data is that cumulative data displays the total amount of information that’s been gathered over a period of time, whereas non-cumulative data shows the amount of information gathered only at a certain point in time.
The simplest way to explain is by looking at this example:
In the non-cumulative chart, you see the number of impressions on a day-to-day basis.
In the cumulative chart, you see how the number of impressions grew over a period of time. Meaning the bar on June 3rd signifies the total impressions from June 1st, 2nd, and 3rd, and so on.
Choosing to display cumulative data is simple, all you have to do is check the Show cumulative data box in the options menu:
