Periodical refresh of a tag history dataset

[Steve_Booth]

I have time series chart with a series that is bound to a tag history dataset. Currently it updates on pull down event script 'onActionPerformed'. It is working fine, but I would like the chart to update every 5 seconds in the browser session.
How can I acheive this?
I considered creating a memory tag that flips state every 5 seconds and the run an event script from that, but it doesn't seem efficient and I couldn't work out how to do that anyway
I feel like there must be an easy way built into Perspective to acheive this functionality.

Thanks

Arrange for your start/end timestamps to be tied to datatime properties that advance every five seconds. Typically by including now(5000) in their expressions.
