Bug introduced in 9.0.0 and persisting through 12.2.0 or later

HorizontalGauge is new in 9.0.0

I am trying to use HorizontalGauge[Dynamic[expt], {0.1, 100}, ScalingFunctions -> "Log"], i.e. a gauge with a logarithmic scale. This creates an error, a graph with a pink background.

Monitoring the output with Dynamic[expt] and a second gauge

HorizontalGauge[Dynamic[expt], {0.1, 100}, ScalingFunctions -> None]

indicates that the logarithmic HorizontalGauge actually generates the expected output. Unless, somebody realizes a mistake in this rather simple code, I must assume this is a bug in Mathematica 9.

EDIT

Unluckily, this error has not been corrected in version 9.0.1

... , ScalingFunctions -> {Exp, Log}

sort of works, but the locations of the tick marks are of course wrong. In the other order {Log, Exp} the error from above is reproduced. I reported this as an error.

  • $\begingroup$ I can't get any ScalingFunction to work correctly. Even #^2& or Sqrt break moving the slider (though the display is correct). But where is this option documented for gauges? I could only find it for charts. $\endgroup$

  • $\begingroup$ For ThermometerGauge it is mentioned in the documentation, and it's also badly broken (you can mention this when writing support as it doesn't seem to be a well documented option). I guess you're right and this is a bug. Also, Sqrt[#]& behaves differently from Sqrt. $\endgroup$

  • $\begingroup$ It's not listed in the examples in the "Option" section. I suppose that is a sign of some kind. $\endgroup$

  • $\begingroup$ @SjoerdC.deVries but, it is listed in Options@HorizontalGauge so it should work. I'll look into it, but it may be a few days. $\endgroup$

  • $\begingroup$ It does not work on AngularGauge too!.. $\endgroup$
