We currently have some dashboards in Pi Data Link. It is easy visualisation with simple graphs with value on Y and tag point date on X.
We want to use PiVision for implementation in our factory on screen displayed to operators.
The problem is trending seems to let you "guess" the value of X which isn't easy to the operators to follow their rythme.
I understand that the value "dropped" between 7:47 and 8:47 but I would like to be more precise and let the user see the exact time underneath.
Is it something that is possible or should I play with event frames and analysis to make that value stand out in the dashboard somewhere else like a value somewhere showing the mininum of the last hour with the timestamp ?
