I’m looking for input on how I might drive a popup using mouseover? I have a set of data that is running realtime, but I want to be able to mouseover that data and display the current setpoint data so there can be a comparison. I have used tooltip mouseover but I have multiple lines of data now so I don’t think the tooltip will work in that case. Any thoughts would be great

~~You can have multiple lines on the tooltips. I have done this before where I have a dataset in a custom prop, for which I build the multiple lines then the tooltip text is bound the the custom prop~~

~~ 

```python
def transform(self, value, quality, timestamp):
	ds = value
	text = ''
	for row in range(ds.rowCount):
		text += ds.getValueAt(row,'Name') +'\n'
	
	return text

```

oof, missed that this was for vision, sorry.

In Vision, you can use the (very limited/poor, don't get too crazy with it) built in HTML rendering support to have a multi-line tooltip, by just writing or returning something custom from the tooltip text property.

So if you set the tooltip text to something like:

```python
<html>This is one line of text<br>And this is another

```

Then it'll render as two lines of text when you hover over it. You can pair that with, for instance, the `stringFormat` expression function to bring in custom properties.
