Correct, the tag history binding always adds the t_stamp as the first column. I see what you are trying to do. In this case you have to make a new dataset in scripting since you can’t remove the t_stamp column. Do the following:
- Add a custom property to the root container called origData that is a dataset. Right click and select Customizers > Custom Properties.
- Bind it to the tag history binding you have right now
- Right click on the root container and select Event Handlers…
- Choose the propertyChange event and use code like this:
if event.propertyName == "origData": origData = system.dataset.toPyDataSet(event.newValue) newData = [] for row in origData: newData.append([row[1], row[2]]) event.source.getComponent("Chart").Data = system.dataset.toDataSet(["Col 1 Name", "Col 2 Name"], newData)Let us know if you have any questions.
