Psychrometric Chart Issue

Hi all,

I am getting an error using the psychrometric chart with values imported from a csv file that I don’t really understand…

Runtime error (TypeErrorException): unsupported operand type(s) for +: ‘str’ and ‘int’

Traceback:
line 931, in colorMesh, “<string>”
line 1819, in main, “<string>”
line 1981, in script
line 4384, in calcHumidRatio, “<string>”

I don’t understand where this could come from. Please see attached a file with the issue.

Aurelien,

Your data is not recognized as numbers but as text and that’s why the chart is not accepting the input. Pass the data through a number component and you’ll be set. See image.

OMG Thanks a lot Abraham,

I was wondering how to correct this for hours… I didnt’ thought Grasshopper made any difference between strings and numbers, so thanks for teaching me this also :slight_smile:
