How to implement permanent

You can achieve that with label text.

Here’s a perfect example:

Hi,

Thanks for the example but it does not help me.

I did save my script on Jsfiddle

Is it too much ask to show me which line I should modifies to show one the the 5 balloons without a mouse?

Thanks very much!

There you go:

Basically I added two lines:

graph.labelText = "showLabel";
graph.labelPosition = "right";

This instructs the chart to look for a “showLabel” field in data and if it’s present show it’s contents next to the bullet.
