Hi all, and thank you in advance. I've been searching before, but I don't find any entry with white pie chart problem.  
I want to output in dashboard 3 values with two charts, bar chart and pie chart. The output is the same. I don't understand why with the bar chart the colors are shown perfect and with the pie chart is all white.

I attach the NR code:

```auto

Um, to save other people grief, how about you post a flow which doesn't need them to have a file existing?

I am suspicious that it is because the data being received is not valid.

But as I can't test the flow, I can't be sure.

Thanks @Trying_to_learn , you are right.  
As simple as data structure was not valid.

Sorry for the my topic format.
