How to change the x-axis datetime intervals runtime.

Hi Patriv,

Thanks for your inquiry.
You can control data interval shown through VisibleRange property on Axes:
https://www.scichart.com/documentation/win/current/webframe.html#Axis%20Ranging%20-%20AutoRange%20and%20VisibleRange.html

we have examples in our Examples App that set VisibleRange to scroll view in realtime:
https://www.scichart.com/example/wpf-chart-example-realtime-ticking-stock-charts/

and a Tutorial that shows a slightly different approach:
https://www.scichart.com/documentation/win/current/webframe.html#Tutorial%2006%20-%20Adding%20Realtime%20Updates.html

As to showing discontinuous axis, we have a DiscontinuousDateTimeAxis which you can use instead of DateTimeAxis or swap them dynamically:
https://www.scichart.com/documentation/win/current/webframe.html#Discontinuous%20DateTime%20Axis%20and%20Double-Scale%20Axis.html

Hope this helps! Please feel free to ask if you need any assistance.

With best regards,
Oleksandr
