I have never fiddled much with charts, and am a bit struggling.
On FM 12 :
Trying to maka a chart of best_times (y) vs date (x).
The records are from 2 users (but there can be more later) : Falco and Tony (see printscreens attachted)
On printscreen 2, you can see the chart, where the data of Tony is appended on the data of Falco.
How can I get filemaker to make a secons graph from the data from Tony, so that there are 2 lines : one for Falco's performance, and one for Tony's performance?
Later on, there can be other users, so there will be more lines on the chart.
PS : wished result shows in attached "wished result.png".
