There is an example of radar chart on OSIsoft's GitHub.

PI-Vision-Custom-Symbols/Community Samples/OSIsoft/amcharts-radar at master · osisoft/PI-Vision-Custom-Symbols · GitHub

This example can show 1 tag/attribute's time series data as a spider chart.

On the other hand, there are some cases that we want to show multiple item's snapshot values as a radar chart.

I changed this sample code and now this symbol can show multiple item's snapshot values.

 

Code is in my github account.

It works by PI Vision 2017/ PI Vision 2017 R2.

Enjoy multi items radar chart.
