Graphs CSV files (a format Excel exports to) exported from Admob, and various other services which export CSV. You can pick 2 columns, one for x, and the other for y to graph.
Consider Installing a file browser on your device. This app will let you pick CSV files directly from the file browser from within CSV Grapher, and via touching a CSV file from your file browser of choice via open with dialog.
- Supports multiple data delimiter (TAB, semicolon, space, and etc...).
- Data is auto sorted based on the X chosen column before plotting
- format auto detected to be either number or date
- Pan and zoom/scale X & Y independently. .
- Very optimized for speed. Browse more than 10K data points smoothly.
If your csv file doesn't work, just email a sample representative of your file and I'll see what I can do to get it working.

The best date time format to use is the following
yyyy-MM-dd HH:mm:ss Z example: 2014-12-31 23:59:59 -0800
yyyy-MM-dd HH:mm:ss example: 2014-12-31 23:59:59
yyyy-MM-dd HH:mm example: 2014-12-31 23:59
yyyy-MM-dd example: 2014-12-31
There are others that are supported. If you are generating the CSV file and want best support/performance use one of the above as it minimizes ambiguity.
By default the timezone GMT is assumed if not specified. Furthermore the displayed timezone in the graph is GMT. Which means is if your timezones that are specified are not GMT (e.g. your local time) then the graph vertical lines for the days will be when the day changes if it were GMT.
When you zoom out technically no averaging occurs. A sample point is chosen intelligently and peaks are given high priority. This allows you to see disturbances in your data such as outliers. One disadvantage is that the graph may look jittery as you move around at a very zoomed out level.
