We use some of the Opto22 groovEPIC devices and one of the built-in gadgets in their groovView HMI is a trend chart that allows you to zoom and slide to get zoomed in views of the chart data.
@Steve-Mcl it's exciting to know that Dashboard is moving to ECharts... after looking at the link you shared it looks like all of the functionality I was looking for will come along with that transition.
