Hi, I’ve been getting a lot of errors in my XY chart. I have copied the sample project chart from the ignition 8 online water demo over (history) and I have adapted it for my needs. I am able to chart things, however there are a lot of errors that seem like it would be a good idea to get rid of. Below is a picture of the errors, which are mostly “Invalid key”.

How can I fix these?  
Also off topic, but how can I make and XY chart show in a step format?  
Cheers.
