I have a RRD-file with one datasource and two archives. The first
archive has the LAST values for the last hour.
The second one has the AVERAGE values for the last year.
Now I want to show both in one graph. If I have the LAST values then I
want to display them, otherwise the AVERAGE values should be displayed.

Currently I've tried something like this:


Where d1a are the AVERAGE values und d1l the LAST values.

I hope you can help me.
