Visibility: Possible to fill the area below a line chart?



…even when the default channel is turned off?


I have turned off the default channel for a sensor and want the remaining line chart to have a filled area below the line. However, this doesn't seem to be possible, as the area is filled only for the default channel.

Please take a look:

1) I have turned off the default channel as shown here:  http://czychi.com/tmp/prtg/no1stchannel.png

2) Now, the second channel is displayed (which should be my first channel), but without the green filled area (that is normally present). I'm not a particular fan of this green color ;-) *but* the visibility is much better if it's present: http://czychi.com/tmp/prtg/nofill.png

Thanks a lot for any hint.

Dear Gary,

this should be possible by setting the remaining channel to be Primary Channel in the sensors Settings tab.

best regards.
