Branched from 196086 ~ Long line from beginning of the axis when using empty points in spline area series

[Christmas Fantasy]

Spline area chart and the data contains few empty points in the beginning because of that i get a long line from the beginning of the axis to the starting  of the spline area series which how ever does not happen on testmyspeed.onl

Hi Christmas Fantasy,

 

We have reviewed your query and created a simple sample by including a few empty data points at the beginning of the spline area series. In our end, the UI did not display a long line starting from the beginning of the axis in the spline area chart.

We’ve shared this sample for your reference. However, if the long line still appears in your case, kindly modify the shared sample to reproduce the issue that showing the line starting from the axis and send it back to us. Additionally, please provide more details about the specific scenario in which this behavior occurs. This will help us assist you more effectively.

@slope games I ran into something similar before, and what fixed it for me was making sure the leading empty values were treated as actual gaps (null/NaN) instead of zeroes, then configuring the empty-point behavior so the series doesn't connect across those missing values. If that's already how your data is structured, I'd also compare the generated data source between your project and testmyspeed.onl to see whether the first valid point or axis settings differ.

@wordle unlimited I’ve seen this behavior with older Syncfusion spline-area versions, and upgrading to a newer chart package or explicitly setting the empty-point mode to Gap is worth trying, since similar long-line issues with leading null points have been fixed previously.
