Change Interval DateTimeAxis

Hi,

I am new to SciCharts and I am developing line chart with multiple line series with different colors. All line series have time span on X-axis and a double value on Y-axis. I need to show time ticks after specific interval for example i need to show tick after every 30 seconds or 1 minute or 3 minute. and may else.I have also took a look at Major Delta and Minor delta but i am confused and not properly using it . And also interval can be changed with at runtime like a user can select that they want to see X-axis time tick after every 30 second or 50 second or etc. Please can you give me and example for it. I hope for Quick repsonse.

    Date majorDelta = new Date(DateIntervalUtil.fromSeconds(1));
    Date minorDelta = new Date(DateIntervalUtil.fromSeconds(30));

DateAxis xAxis = sciChartBuilder.newDateAxis()
.withAutoRangeMode(AutoRange.Never)
.withSubDayTextFormatting(“mm:ss”)
.withMinorDelta(majorDelta)
.withMajorDelta(minorDelta)
.withAutoTicks(false)
.build();

Best Regards,
