So the standard Chart component for Vision could manually plot data points, but would it be possible to do this using Easy Chart too? I ask because we want to compare pens, and the data source is from a web service endpoint vs. Ignition tags.
You can only use the given data pen options (Tag Historian Pens, Database Pens, or Calculated Pens).
The standard chart component is far more flexible for use in this case, you just need to build the dataset.
So I guess the answer to your question is "maybe", depending on how much work you want to do to get the data into a format that it can be used with the Easy Chart.
Thanks, but I want to see if I can avoid back-filling this data into Ignition historian or another database. Doesn't the Easy Chart component inherit from the Chart component and the Date Range component? I'm hoping there's a way to code it through Java.
What does the easy chart offer you that you can't achieve through the regular chart?
You can query tag history using a binding and compare that against whatever dataset from scripting on the same "classic" Chart component.

No, it does not. They both inherit from an intermediate class.

Development are all using the Easy Chart component for trends. Now with this new data introduced, we will have to review the effort swapping all the windows to use the Chart component and matching the same functionality the Easy Chart was doing. I guess I have concerns we might not be able to match everything the Easy Chart was doing.
It takes some work, but everything that’s being done in the easy chart (and more) can be accomplished with the standard chart component.
You get to decide what work you want to do, making the data available to the easy chart, or making the standard chart work for your needs.
