Creating a RadChartView, both with a single series and multiple series for a DateTimeCategorical axis. Some series have gaps (null values). I'd like the series to close up this gap in the line, connecting the two data points. I cannot find an option to do so. See the datagap.png and datagap2.png attachments for an example.
Some workarounds I've tried is to not add a data point at all for that date when the value is null, but then then that date doesn't show up in the category. See datagap3.png for an example.
Is there a setting to close this gap in the line, or am I using the wrong chart or series type?

RadChartView supports empty values in the series. The empty X value is skipped from drawing: https://docs.telerik.com/devtools/winforms/controls/chartview/null-values-support-
If you want the chart to behave as if the null value is not there, the possible solution that I can suggest is just to remove the empty value from the data collection you are using for populating the data.
Alternatively, you can consider using RadSparkline: https://docs.telerik.com/devtools/winforms/controls/sparkline/overview
The EmptyPointBehavior property controls what happens with null points. The possible values are:
- ShowAsBlank: The null points would not be painted on the chart and a blank spot will appear.
- ShowAsZero: The null point will be considered as 0 on the Y axis.
- DoNotShow: The null point would not be painted on the chart.
More information is available in the following help article: https://docs.telerik.com/devtools/winforms/controls/sparkline/features/null-values
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
