Multiple x-trace points in easy chart

When trending data in a chart it would be nice to have the possibility to x-trace multiple points on the chart. This way it is easier to highlight and compare the difference in values over time.

Second vertical line for x-trace

In a prior SCADA software that we used, we were able to create two vertical lines on charts. A single click would put the normal line on the chart and give you the values of the pens at that point in time. A double-click elsewhere on the chart would put a second line on the chart and the pen readouts would switch to showing the difference between the two points in time. The time difference was also computed and displayed. This was very helpful in quickly determining how long an event lasted, or how much a reading changed in a given amount of time. The two lines were cleared by clicking the labels that appeared below the chart.
I think something similar would be useful for the charts in Ignition. Some similar mechanism to trigger the second line like a shift-click could be used. Ctrl-clicking or Alt-clicking the chart could clear the lines.

Yeah, that is very helpful, I used it in Vantage Point from Rockwell software and I hoped to see in Ignition but it was not like that.
I would like to see the second vertical line for x-trace soon.

This is on my to-do list as an addition to the NoteChart module in the marketplace.
