Trend Graph And Virtual Channels

[prospective]

I would appreciate help on the following:

I am trying to plot a simple trend graph where the Y axis will be a v-channel. I cannot get my v-channels to have time-stamps associated, so the trend graph also don't work....

For example, in my sequence:

While(1)

v.vaue = 5

wait (0.5)

endwhile

plots perfectly as the time stamps are present with each reading

BUT

While(1)

v.vaue = var.othervalue

wait (0.5)

endwhile

does not work as all values are written against the same time, eg the time don't update????

I realize I am making a stupid mistake somewhere or don't know the rules well enough??

Many thanks!!!!

Use inserttime() to force a time stamp:

V.vaue = insertTime(othervalue, systime(), 0)

This gives it the current time at the moment of execution.
