Is there way to manually scale the intensity of the QT waterfall sink, in other
words, set the dynamic range and reference level like the WX sink?
Adjusting the time axis with the scroll wheel alters the intensity axis, but the
actual color values don’t change.
Just to make sure, are you using the QTGUI “sink” (the one with tabs
for the different types of plots) or the “waterfall sink” (with /just/
the waterfall). If the former, there should be two bars for the upper
and lower intensities that will affect the colors.
If using the waterfall plot directly, we haven’t instrumented the
min/max from the gui directly (to avoid clutter). However, the object
does export the set_intensity_range(double min, double max) that you
can use to directly control these.
Alternatively, with this plot, if you middle-click on the mouse, the
drop-down menu offers an Auto Scale feature that will adjust the
dynamic range based on the min/max values in the current plot. I’ve
found that to be the most useful way to control the intensity.
