Hi there,
I am interested in graphing some real-time measurements but am unable to select the points which I wish to trend. The check box is grayed-out and when I select the point name, I am redirected to another page. Is there some additional requirement for trending points?
Hi jarurlaj,
The trend chart has four y-axes for plotting measurement values. As a result, that page can only trend voltage magnitudes, current magnitudes, phase angles, and frequencies. Unfortunately, there is no y-axis for analog values. I’d say your best bet for a workaround is to temporarily change the signal type to “voltage magnitude”.
Thanks,
Stephen
You can also open the openHistorian Web interface, commonly at http://localhost:8180, and click the “Real-time Measurements” button from the home page.
