I was just hoping someone from Weather Underground reads this.
I think it would be nice to have graphing of outside humidity readings. Just a feature request. Should be simple since they are already getting this data.
WU should display humidity inside the temperature and dew point graph, since dew point is calculated based on temperature and humidity, so they are related. I don't want an extra separate humidity only graph. Just make it a different color line inside the temp/dew point graph. And add the humidity percentage scale to the right side of the graph as that is currently free for labeling.
I know, I know. Before anyone jumps on my back... Yes Weather Underground should fix a bunch of broken things before they waste time adding new features. I just thought I'd throw this out there for hopefully near future consideration.
