What happened to my PSYCHROMETIC CHART?

The location is Hangzhou, Zhejiang, China.
Just as the picture I uploaded. The comfort polygon has fallen completely off of the psych chart.
What happened to my psychrometric chart?!

There is no comfort polygon on my psychrometric chart…

Hi,@Jocelin I just did a same grasshooper definition. I worked fine on my computer.I suggested you check the Units setting in Rhino. I used Meter and generated normal psychrometric chart.

Thanks @minggangyin .My psychrometic chart is fine in a new GH file.Maybe the problem is the unit.I will check it later.

I found the problem.It worked when I updated Ladybug.Maybe something wrong in the LB version.
