Solar Radiation graph not showing Radiation data

[caphector]

I've been trying to add Solar Radiation graphs to my install, but I can't seem to get solar radiation to show up on the graph.

My weather station (a GW1104) reports solar radiation and UV index; I can see both on the station's home page. The Weewx DB has a radiation column with data and my MQTT output has uvradiation and uv.

I added the UV and Solar Radiation graph (https://github.com/poblabs/weewx-belchertown/wiki/Belchertown-Charts-Documentation#uv-and-solar-radiation) to my charts; it picks up the UV Index just fine, but I don't get a Radiation line. The chart's source also shows no data, suggesting that this is failing to pull the Radiation data while generating the charts. I don't see any errors in logs during a chart generation, so I'm not sure how to dig into the failure here.

I kept working on this after posting and it started working. I believe the major changes I made were to add the radiation observation to my station config, but I'm not sure.
