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:

Hope this helps!

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

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