I think that most people are using this site http://www.digitalpoint.com/tools/adsense-charts/ to figure out the total number of hits on their adsensewebsite and to present those data on a line chart.
You can also create your own adsense graphs by following these simple steps:
- Download the CSV file from Google and take the All time report, because if gives a larger sample size.
- Open an MS Excel sheet.
- Open now the downloaded CSV file in Excel and you'll see a table of figures.
- Delete the column heading marked Date and the rows at the bottom of your sheet that indicate Totals.
- Highlight column A (should be date) and highlight column B (most likely to be Page impressions) and go to Insert > Chart. Go through the wizard looking at the different charts you can make. Settle on the first bog standard line graph. Next, Next, Next, until you hit the part that asks where you want to create it and than click Finish.
- Repeat the same for the other column
