Time Series Chart Markers

Ignition

I’m hoping someone can shed some light on markers 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
