Trends Chart with Tag Filtering

Ignition
1

Hello!
I'm beginning a project in Ignition and would like to set up a trends chart similar to one I used previously in FactoryTalk HMIs. In my FactoryTalk setup, I had a button that opened a trends screen. On this screen, there was a menu allowing operators to choose between live data and historical data (from data logs). The operator could also filter by screen and then select specific tags they wanted to view.

In summary, I’m looking to:

  1. Allow operators to toggle between live data and historical data.
  2. Filter data by screen.
  3. Enable tag selection for specific displays.

I haven't started development yet and would like to know the best way to organize and distribute tags in Ignition to achieve this setup. Is there a recommended approach for setting up these filters and tag selections in Ignition?

Much of what you are after is available with just a bit of "construction" in Vision.

The EasyChart component has both real time and historical modes, switchable at runtime with a separate checkbox or pair of buttons.

The EasyChart also supports runtime drag-n-drop of tags from the Tag Tree component, which can be made to show just the tags you are interested. Another button to make such visible, or make it pop up, would probably do.
