Perspective Power Chart – Plotting one History Tag multiple times on the same chart

Ignition
1

Hello all,

I have created a View that contains a Power Chart component. The mode for this component is set to historical.

Goal:
I want the ability to produce a plot of Tag1 (aggregated mode set to Average) and Tag1 (aggregate mode set to Maximum) on the same chart.

Problem:

  1. After adding Tag1 to the Power Chart from the Tag Browser, the Tag Browser did not allow me to add a second instance of Tag1. As a work around I performed the following:
  • Created a second Pen (Pen 1), in the Perspective Property Editor.
  • Copied the source location from Pen 0, data section.
  • Pasted the Pen 0’s source location into the source location of Pen1

The result was two identical plots of Tag1. So, I set the aggregation mode to Average for Pen 0 and the aggregation mode to Maximum for Pen 1. Expecting to see two distinct graphs with different data points, both graphs remained the same.

Proposed Solution
I am thinking about creating a second tag, Tag2, that is collecting the same data as Tag1. This will all me to plot both Tag1 and Tag2 independently of each other. The solution will cost me disc space, since there will be two History Tags with the same data.

Any idea?

Best

You may have to not use the Power Chart. You can use multiple tag history binding with a TimeSeries chart, referencing the separate queries in your plots.

(Though the TS chart will make you tear your hair out, it is so laggy. Use Apex Charts or perhaps Embr Charts instead.)

I'll take a look at these options. Thank you
