Going to need more information. Where are you trying to make this binding? ---

Hi Sorry about that. Upon opening my pop up, I want to be able to pass a certain parameter to the chart (current value, past value of a selected setpoint) (ofcourse this would be different based on different tag values). Does this make sense? ---

Sure, that says what you want to accomplish, but not how you're trying to accomplish it or what is giving you issues. Have you looked at this: [https://docs.inductiveautomation.com/display/DOC81/Parameterized+Popup+Windows](https://docs.inductiveautomation.com/display/DOC81/Parameterized+Popup+Windows) ---

Hi Thank you for that feedback: So I already have a pop window where its accepting parameters from the main window. So right now its passing PV,SP,CV values from the main window to pop up window based on the tags I am clicking on on the main window - just like the docs you attached. What I CANT do now is pass a parameter to a chart - to show the visualization of current and past setpoints. When I drag an existing tag to a chart and try to bind with a parameter it is not working. I don't even see an option to do it on the property editor. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/8/68ab3b560e09316e0a591b581371e56caf733bac.png) ---

> [@prii1997](#): > > When I drag an existing tag to a chart and try to bind with a parameter it is not working I don't understand what you're attempting here. Are you trying to indirectly bind tags to the chart? What chart component are you using? ---

II am trying to bind a tag to the chart. To make it look/work like this. I am not sure how I would achieve this in V8.1 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/b/6b63b5c5c3cf9e75be186e432278474fcee940bd.png) ---

As you have found, you can not "Bind" a tag to the chart. (Either Easy Chart or Standard Chart). Instead you have to add a row to the `tagPens()` Dataset on the easy chart, or you have to manual construct the dataset for the standard chart. This can be accomplished from a property change script on you custom properties. You should be sending the tagPaths to the popup to be processed there. ---

Hi, can you please make an example and show how to do this?
