I have a power chart designed to display tags. How to take aggregate values of powerchart such as Maximum values, Average values to display on the table.
Welcome @Kannan_Karunanithi.
You can find further information on the power chart here: Perspective - Power Chart - Ignition User Manual 8.1 - Ignition Documentation
Are you aiming to display these aggregations in the table underneath the chart? If so, you will need to configure the dataColumns property as required. Note the difference between penControl and rangeSelection.
If you are aiming to take the the aggregations out of the chart and put them in a seperate component I don't think this is possible. In this case you will need to perform the calculation on the source data and pass it to the appropriate component(s).
