THANKS Hello We would like to create a similar curve in winCC V11, But we can't find the right way to do it. Suggestions someone? Thanx Pietr Hi, I am trying to do something similar, but having trouble setting it up. I have 10 X values, and 10 Y values. They can be changed on the screen, but that will seldom be done. I would like to show the points on the chart with a line connecting them. Where can I set the number of points? And somehow it seems to be wanting a time on the X axis, how can I fix that? Any examples would be very helpful. Thanks!

K!ke Posts: 1299 Rating: (136)	Hello, there are demo projects available, they use the f(x) trend view. I've seen it in the demo project for wincc runtime advanced, but I'm pretty sure the projects are very similar. http://support.automation.siemens.com/WW/view/en/73468169 K!ke

And need to show these points on a chart, interconnected by lines. the chart only needs to be updated once, when the screen is loaded, and alternatively when an update button is pushed.

K!ke Posts: 1299 Rating: (136)	Hello, so you have 20 different tags you want to display with this curve? Which target system do you use? Panel/Runtime? K!ke

K!ke Posts: 1299 Rating: (136)	Hello, maybe you can solve the problem by usinga script. I don't have an eloberated script justsome ideas, e.g. write the values (one after the other) in another tag which you can use for the f(x) trend view? Or you make your own "trend view" with some lines which end points you can change. disadvantage: you can't change the rise of the line just the end points... K!ke

I think I need something like the Bit-triggered trend with buffered data for the f(x) trend control. But I could only find Bit-triggered trend with buffered data in the standard trend control and only in the comfort panels, not in the Basic panels. Kind Regards, Johan
