count above

[#1]

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.
