Hello,

I’m trying to analyze a device’s status. I was looking at how to use the status chart, but I didn’t find any info about how to config it. The tag values that I receive are “OK” when the device is online and “null” when the device is offline. Could you give me any recommendations to graphic those historical values?

Hi,

The 7.9 documentation for the Status Chart can be found [here](https://docs.inductiveautomation.com/display/DOC79/Status+Chart) if you haven’t had a chance to check it.

As for trending the status of a device connection, you could set a device’s IsConnected tag with historical properties. The page link below mentions where you can find this tag:
