I have created an easychart which gets information from another tag on another screen by passing easychart dataset.

I have then created an analog indicator that shows up on the trend that shows alarms and lets them be changable.

My issue is that when the easychart is zoomed in i cannot get the analog indicator range to change based on the easychart upper and lower bound.

I know this can be done easily the other way around but cant seem to find the information for this direction.

I am new to java and am not sure how get the upper and lower bound information to use elsewhere.

Any help would be appreciated.

Here's a way to get all four bounds from an easy chart when in zoom or pan mode:

> @June_Zhu - I finally figured this out. I was able to get all four parameter values in an easy chart from a test button using the following script: chart = event.source.parent.getComponent('Easy Chart') leftDomainX = chart.getZoomedStartDate() rightDomainX = chart.getZoomedEndDate() lowerRangeY = chart.getComponent(0).getComponent(0).chart.getPlot().getRangeAxis().getLowerBound() upperRangeY = chart.getComponent(0).getComponent(0).chart.getPlot().getRangeAxis().getUpperBound() print "Current Y…
