Hello Brad_Kim!
Welcome to our forum and thanks for contacting us with your question!
To zoom between two ticks you can set
chart.zoomType to x/y/xy and then mark the area you would like to zoom. You can also do this programmatically by using
axis.setExtremes method which will zoom to the area with your selected min and max values.
