How can I add a desired range to the timeseries chart in perspective? Similar to the sparkline component.

Thanks.

@michael2, you’ll just need to create a `trend` and have it use an `axis` that you create with your desired `min` and `max` values:

@jball Thank you for your reply, however it’s not quite what I’m looking for. I’m looking to implement a desired range similar to the one available on the sparkline component; the actual process range may be larger. I would like to have the blue range on a time series chart as shown:

@michael2, sorry; totally misunderstood. We don’t have that yet for the time series component, but I’ll be building a “band” marker for an upcoming component that you’ll be able to use here that will give you this functionality.
