Trend Indicator on Humidity Gauge

Postby K8POS » Mon Dec 11, 2017 3:40 am

Have searched this forum for 2 hours looking for this. Has anyone added a trend arrow to their Humidity Gauge?
I have locked out the Indoor readings for both Temperature and Humidity.
I was looking at the Gauges.js to see how the trend indicators were done.
I can see on line 738 this code: params.trendVisible = gaugeGlobals.tempTrendVisible;
I think this turns it off/on for the temperature gauge.
I also see about line 1404 where the humidity Gauge is defined.
Could I just include the line to add the Trend indicator, or do I also need more parameters.

You'd first have to calculate what the trend was, Cumulus provides the trend for temperature but not for humidity. You'll therefore have to devise a method of determining it yourself.

Once you have that, then add it to the JSON file, and copy the code in the temperature gauge for display the value.

Some day I'll ask a question that has a very simple solution.
Have tons of reading to do now.

Thanks
