QT GUI frequency plot scale

Hi all,

I’m going through some of the GNU Radio tutorials and I noticed that the
frequency axis for the QT GUI frequency sink is incorrect for real
valued
signals (e.g., sample rate of 10k shows -2.5k to 2.5k). I found a bug
report (#541) from last year with the issue resolved in 3.7.0, but I’m
working with version 3.7.2.1. I didn’t notice any other bug reports
regarding this issue.

Note: The frequency plot in QT GUI sink is scaled correctly. Also,
updating
the sampling rate while the flow graph is running corrects the scale.

Hi Mike,

I think this was (should be) /fixed/ fixed in the 3.7.4 release. Check
out
the commit:

There was some back-and-forth I did between versions of QWT, and this
seemed to be the last stray issue that I found.
