Stepped Line Chart in SAP MII SSCE

Hello experts

I got time series data i am trying to visualize

y axis is a discrete value and x axis is the corresponding start time (that is the time when y value got measured). The next measuring point will only be created when the value changes.

I visualized this in SSCE but I do not get the desired output. Cause when the status changes, the line chart interpolates the values between old status and new status.

What I am looking for is a way to get a stepped line chart. That is a horizontal lines is shown until the next measuring point indicates the value changes.If value changes, vertical line is drawn followed by a horizontal one indicating the new value level

Is there any mean to do so in SSCE?

For sure I could change my data and use one row for start time and one row for end time but I would prefer not doing so...

Thanks for help
