I'm sorry but it is still not clear to me what the exact issue is. I've opened the image from your original post on a better screen and as far as I can see the gauge shows rain rate in mm/hr, the labels across the top of the plot show rain rat win mm/hr but the y-axis label of the plot seems to show in/hr. Is the problem
only the y-axis label being in in/hr? Do the rain rate values show on the gauge and in the plot correctly as mm values or as inch values? (ie does the gauge indicate 5mm/hr when in fact the actual rain rate is 5mm/hr or does the gauge show 5mm/hr when in fact the actual rain rate is 5in/hr)
Finally, what are you using to generate the
gauge-data.txt? Have you installed the skin direct from the
SteelSeries-Weather-Gauges repo or did you install the
weewx-steelseries extension ? In either case could you please post a copy of the
[StdReport] [[SteelSeries]] stanza from
weewx.conf along with a copy of the skin config file,
skin.conf, from the
skins/ss directory. (note the location of the
skins directory will depend on your WeeWX version and how you installed WeeWX - refer to
Where to find things in the
User's Guide for your particular WeeWX version).
