Building the submenu is a little confusing but the actual logic to get stuff to the window instance is pretty simple. The other chunk of scripting is to take the passed tagPaths and build the proper chart configuration dataset from them.

> 
> # Add the selected data item's path/id to the dataset
> newTrendItems = system.dataset.addRow(trendDataItems, row=[selectedDataItem])

Using the above project library functions I then made a template that is just the analog value display, that takes the tag path for the analog display.

On the template 'mouseClicked' handler I put:

```python
if event.button == event.BUTTON3:
	newMenu = path.to.project.library.package.buildAnalogDisplayContextMenu(event)
	newMenu.show(event, event.x, event.y)

```

I have pturmel's [Integration Toolkit](https://forum.inductiveautomation.com/t/automation-professionals-integration-toolkit-module/74934) installed so I'm able to make the required trend dataset using the following expression:

> **Trend Dataset Expression**

> ```python
> unionAll(
> asMap(
> "NAME", "str",
> "TAG_PATH", "str",
> "AGGREGATION_MODE","str",
> "AXIS","str",
> "SUBPLOT", "I",
> "ENABLED", "B",
> "COLOR", "clr",
> "DASH_PATTERN", "str",
> "RENDER_STYLE", "I",
> "LINE_WEIGHT", "F",
> "SHAPE", "I",
> "FILL_SHAPE", "B",
> "LABELS", "B",
> "GROUP_NAME", "str",
> "DIGITAL", "B",
> "OVERRIDE_AUTOCOLOR", "B",
> "HIDDEN", "B",
> "USER_SELECTABLE", "B",
> "SORT_ORDER", "I",
> "USER_REMOVABLE", "B"
> ),
> if(

> asMap(

> "TAG_PATH", "[ProviderName]" + if(
> len(split(it()['tagPath'], "]")) > 1,
> lower(split(it()['tagPath'], "]")[1,0]),
> it()['tagPath']

>

Otherwise, you'll need to make an additional project library function to take the single column dataset `trendItems` from the trend popup root container and transform it into the required dataset for the trend chart.

The required properties on the trend popup for my script to work are `windowId` of string type, `trendItems` of dataset type, and `trendId` of integer type.
