Psych Chart: index out of range error


I’m seeing an error in the last few days with the Psych Chart component

  1. Solution exception:index out of range: 0

It seems to happen when I connect the Relative Humidity wire.

Thanks in advance for any help,


for a bit more info, these are the error messages in the readme output.

Runtime error (IndexOutOfRangeException): index out of range: 0
line 803, in drawPsychChart, “”
line 1925, in main, “”
line 2186, in script

any help appreciated, I know this isn’t the sexiest component and seems to frequently give issues…
