Hi everyone,

I'm looking for a way to update a time series chart while using the "enablePanZoom" PROPS.

I have a table with selectable devices, in the chart, it's displaying relative information to the device. I wish to be able to lock the selectable table from selection while zoomed in or just reset the zoom when another device is selected but I can't find any event related to the zoom to bind my script on.

I know that according to the documentation

> The Time Series Chart will not refresh its time range if it is zoomed in. It maintains the zoom while polling. [source](https://docs.inductiveautomation.com/display/DOC80/Perspective+-+Time+Series+Chart)

which is troublesome.

Is anyone found a workaround for this problem? Any help would be appreciated, thanks in advance 🙂

Using Perspective V8.0.11

@valotaire.alexis, you can use the [Chart Range Selector](https://docs.inductiveautomation.com/display/DOC80/Perspective+-+Chart+Range+Selector) as a way to drive the display of the Time Series Chart. You’ll need to use the `selectedRange.start` and `selectedRange.end` values of the Chart Range Selector to drive whatever query you are using to feed data into the Time Series Chart. By doing that, you’ll be able to reduce/enhance the data displaying on the Time Series Chart without zooming the actual chart in/out.

@jball Thank you for the answer, I’ll try that.

I’m using the Chart Range Selector to move and zoom around the data in the Time Series Chart. Instead of re-querying the chart data (SQL Call) whenever the chart range selector date range changes, is there a way I can simply change the displayed date range of the Time Series Chart, in the same way as scrolling the mouse wheel? All the data is already in the chart and I just want to display a sub-set of it.

Currently, we don’t expose a way to adjust the level/position of zoom via component properties on the Time Series Chart. That’s driven solely by user interaction (mouse wheel or pinch/zoom gestures) That Chart Range Selector is still the best option for “honing in” on data from a larger dataset.
