Update - the runs I’d been looking at had a single bin spike in one spectrum (detector/DAE fault?) so it probably was auto scaling correctly even though I couldn’t see the one yellow pixel. The log scale bar feature is still broken with other data.
A colour fill plot should initially auto scale its axes to show the data. The scale bar at the right should reflect what the plot is showing.
On opening the plot it may be solid purple. I can use the dialog to rescale the “colour” axis - typically I need to reduce “Max value” by a factor of 10 for raw muon data. It is making some incorrect attempt to scale the data as the initial “Max value” varies between runs.
If I select scale=Logarithmic, the plot area changes as expected but the colour bar at the right still has linear ticks.
Load a run in Muon Analysis 2. Find the xxx_raw_data workspace (inside a group for its run). Right click - Plot - Colorfill. Then try the plot’s settings dialog, Image, and select Logarithmic.
