On the PLC I have an array of DInt values for the last 100 process measurements taken at a specific point in the machine's cycle. I would like to display these as a chart so the operator can see if the values are stable and not creeping up or down. I have messed around with the Trend Control as well as using triggered logging tags but the X axis on the graph is always time based and is always scrolling forwards, even when the machine is stopped and not making new parts.

In the older WinCC RT I accomplished something similar with a Trend View with a 'bit triggered real-time' trend type.

Is there something I am missing in Unified or is there another way to accomplish this?

Hi Sim00000n,

Maybe this forum post about how to insert non real time in trends in Unified can help you, I recommend you to have a look at it:

WinCC Unified – Simple Sample - Inserting non real time information to Logs / Trends (manual write)

Hi, I have the same issue, data is stored in an array, which should be displayed in a trend graph.
In the comfort panels we used a bit triggered trend view to do this.
With the unified panels, I just can't figure out how to do this.

Y axis should be set according to the data in the array

X axis should be the array number (in our case 1..999).

Any suggestions?
