Hello,

Can I plot a chart using 2 historical tags (time dependent): one on the X axis and the other one on Y axis? I don’t want to have a time axis, nor a log axis, etc. I want to plot historical tag 1 x historical tag 2. Is that possible?

Thanks in advance!

Yes, but not directly. You’ll have to use the classic Chart component instead of the EasyChart, and you’ll have to place your history query outside the chart (on a custom prop on its container, perhaps). Then whenever data shows up in that property, you can construct a dataset without the timestamp column and assign it to the dataset in the Chart. I would use the [view()](https://www.automation-pros.com/simaids/doc/expression.view.html) function from [Simulation Aids](https://inductiveautomation.com/moduleshowcase/module/automation-professionals-llc-simulation-aids) for the latter, fwiw.
