Hello,

i'm using the QwtPlotMarkers to indicate values that underrange a lower limit.
I have enabled autoscale on yLeft. The top part of my picture shows
the plot during measurement and you can see only a part of the arrows going down.

When use the panner to move the content i can see the arrows.

Is there a way to change the autoscale function that it recognized my makers?

Hint:
The probem happens only if the curve where i attached the arrows is also
the curve with the lowest measurement points of all attached curves.
If there are lower y values of any curve the yLeft shows the next decade and the arrows are visible.
