Dear All  
Iam new to Ignition and Iam making template where I can bind custom property into Tag history so i can use sparkline chart in template.

So when I use template i just bind custom property to tag and it used history of that tag.

Can you please navigate me how to do it or where i can find manual how to do it  
I searched documentation/help/university but was not successfull

Best Regards Jakub

It sounds like you’re using Vision, in which case, you can create a Template param which contains a tag path, for example, and then bind the sparkline chart’s `data` property to a **Tag History** binding. Use indirection to pass in your template param into the Tag Path. Example below, where `PumpTrolleySignal` is the name of my Template:
