How to change plot line colors using a Time Series Chart and Datasets for series

Hi all, I'm currently following the steps described in this post: Perspective - Time Series Chart , how to change color of line chart? - #4 by nminchin to troubleshoot my issue where I cannot find a way to change the individual colors of my plot lines when using Datasets. The reason I am using datasets as opposed to something static is so that I can display real time moving data.

In the image, you can see how I am using Datasets for each entry, but doing this does not allow for customization of the line colors. Under columns[0]/colors it is changed to red but the line remains blue. I cannot use TemperatureData as a key for the column because when I do it does nothing.

Any thought? Thank you!

Can you try setting the columns/0/key value for the trend 0 (the one with TemperatureData) to be the name of the column in the dataset with the values?
Eg if your "TemperatireData" dataset has columns time_stamp and measured_value, set the column key to be "measured_value"
