We would like to inform you that the SfDateTimeRangeNavigator lower label bar’s labels does not rendered based on the chart axis (content of SfDateTimeRangeNavigator). So, the alignment between its lower label bar and the chart axis(its content) gets differ.
We suggest you to collapse the visibility of chart axis ,while placing chart as the content of SfDateTimeRangeNavigator. Since we can see the content range in lower label bar. However, if your requirement is to align the chart axis with the lower label bar, then we can align both , by adjusting the position of chart axis. We have prepared a demo sample based on your requirement and it can be downloaded from below link,
