Step / non-interpolated charts for status values

Ask the community

Hi,

We are visualizing time series data where some variables are continuous measurements, while others are pure status or mode values (for example Off, On, Fault, etc.).

In the built-in chart components, line series always interpolate between points. This works well for continuous data, but for status values it becomes misleading. When a status changes from one value to another, the graph shows a gradual transition, even though the change was instantaneous.

What we would need for status values is:

  • Step / hold-last-value visualization

  • Horizontal lines between changes

  • Instant jumps at the exact time of change

  • No interpolation between different states

Questions:

  • Is step / non-interpolated visualization supported in any of the built-in chart components?

  • Are there recommended workarounds besides custom coded components?

Being able to mark a variable as “status / discrete” vs “continuous” would greatly improve time series visualizations.

Thanks!

Hi!

This can be achieved using the advanced line chart. Enable Disable Bezier and Show Steps, then set Step align to Left, and you will get a more step visualization, as shown below:

Hi again, thanks for the quick response. Is it possible to add this functionality to the Combined chart as well? :slight_smile:

I am not sure if it is possible, but I can send this in as a feature request to the development team:)
