Oscar graph scales

Oscar graph scales
My apologies if this is previously answered, but I couldn't find it.

For reasons I can't discern, the scale on the left side of OSCAR graphs seems to change over different days.  Could be that it changes when I change settings.  I'm mainly interested in the pressure graph right now.  I'm finding that the values on the graph exceed the maximum shown on the graph.  Is there a way to manually change the maximum value shown on the graphs?

Thanks for the ongoing help - it's been invaluable.

The default scale is auto.  By right clicking in the chart title (Pressure) block, click on y-axis. Then select Manual Override and fill in your desired values.

Good catch Red

RE: Oscar graph scales
Right-click on the graph label.  Look for:  Y-Axis -> Scaling Mode (dropbox) -> Override.  You can set the minimum and maximum there.

RE: Oscar graph scales
Thanks - got it!  I'm wondering if a better default would be the minimum and maximum, either for the particular day, or for some specified period.

RE: Oscar graph scales
I've found that most days are normal and the Auto Scaling mode works fine.  Then there are those days that just seem to go sideways and require scaling intervention.  I usually adjust it to look at those days and then put it back to auto.   I can't find any rhyme or reason as to why this happens.
