Hi
I have a file with 2 fields Month and Idclient
I' d like to count in a chart for each month how many new clients I have
Example
Jan 10 => 10 new clients
Feb 13 => 10 clients from Jan + 3 news
Mar 20 => 13 clients + 7 news
...
How to achieve this?
Regards
JJJ
Here's an example that might be useful. It shows new, lost, and retained customer for each year for each service type. It's fairly complicated the way I did it, so it wouldn't surprise me if there's an easier way.
