C-more EA9 line trend graph Y Axis scaling for pens with different ranges.
I may be completely missing it but i would like to use a line trend graph to display several tags with different min and max ranges that need to be displayed the same HMI line trend graph. Is it possible to have multiple ranges display on the y axis with an EA9?
What I have done (kludge) is do some math to make all the tags be of the same range, and graph those. But it's clunky and may or may not be confusing to the viewer.
^ Same here.
Depending on your graph config settings, you can turn off desired pens.
It would be nice to be able to turn off individual pens by PLC code (or HMI event manager.)

Maybe convert all to a percentage and then graph. 0-1000 represents 0 to 100%

while that would work in some situations the end user for my project needs to be able to fallow the graph at an instant.
i started looking at advanced HMI but am not seeing how to do it there as well.
currently i think i am just going to write something in python using matplotlib to make the graph
Question:..
How do you get a Python Script into a PLC ( Which One! ), and then get matplotlib to Display in an EA9?
Cap
I am not going to use a EA9 instead i am going to use a PC with a monitor running the script
I am bringing my old thread back from the dead.
I would still like multiple y axis for the trend graph. This time I am using a CM5 panel for a wastewater line and I would really like to put tank levels in feet, flows in GPM and Pump speed in RPM and a few others on the same line graph. The line graph isn't necessary for this project it is just a nice to have so the wastewater tech can look back and see what was going on.
