[Solved] TChart and Date in X Axis

[berghem]

Hi all

in my app I  collect a lot od data from my temperature probe and I have to put the value in Y axis and I want put the date in X asset.
I collect data every 60 seconds from a lot days (circa 15 days) and I wont put the date one time per day.
I saw TDateTimeIntevalChartSource but doesn't work I use this commad
Myseries.add(value, DatetoStr(Now)

Can you help me?

MySeries.Add does not store the date/time of the temperature measurement as X (which is taken as the index of the data point). You should use AddXY(x, y, ...) instead:

Code: Pascal  [Select][+][-]

1. Myseries.AddXY(Now(), Temperature);

In the attachment you find a tested demo project with lots of comments.
