@mcigorli,
1. How to make the navigator follow the new data if the navigator is in the far right corner?
Please check this gallery page for an example of a dynamic/live stockchart where the position of the slider is updated as new data is added to the chart.
2. How to make a gap at the beginning as shown in the picture?
You can set the x-axis viewPortMaximum to a value greater than the last datapoint to add gap towards the right side of the chart as per your requirement from the screenshot.
