Issue Details

When working with waveform channels in 2D axis system of NI DIAdem, X-constant disappears (the red line in the second screenshot) from the plot after changing the unit of time on the x-axis (for example, from seconds to ms). How to resolve this issue?

Solution

This is an expected behavior. If channels are displayed in a 2D axis system with certain numerical values and if a constant is added within the value range of the channels, it will be displayed together with the channels. If the initial time unit has changed, then the constant will not be visible in the changed graph. 

To avoid this behaviour, X-Channel value can be represented as shown below:
 @@VU(value, "unit")@@
