I’m hoping someone can shed some light on [markers](https://www.docs.inductiveautomation.com/docs/8.1/appendix/components/perspective-components/perspective-chart-palette/perspective-time-series-chart#plotsmarkers-properties) within the Perspective Time Series Chart. I’m on version 8.1.44 and have been unable to get a marker of any form to display on the chart. Can someone post an extremely basic example JSON of the chart with a marker? Maybe just the default chart config with the default data including one vertical marker added. Is this known to not work?

Note: I can successfully add markers to the XY Chart, but no luck with the Time Series Chart.

Try adding the series name under `props.plots[0].trends[0].series`

Here is a working Time Series Chart with a single line marker:

Thanks this is great. Is it possible with this component to have a vertical marker or only the horizontal?

I was able to add a highlighted range to the chart. I think these are all of the steps I took, but I attached an updated view with an example in case I missed something:

- Add a new series with the start and end of the range you want, with a value of 1 for each
- Add a new axis, set the width to -1 to hide it, and the min/max to 0 and 1
- Add a new trend with props.plots[0].trends[1].type set to "area" and set the axis and series to the newly created ones
- Add a column to the new trend and set the key to the new series x-axis key, and set the color to something with opacity

Thanks! This may be a viable work around. But I may have to fall back to ApexCharts to obtain a vertical marker. I feel there is something lacking in this component which IA may want to fix because it seems like a vertical marker should be possible.
