# scrollbar

The scrollbar is a means of panning over the X axis of a stock chart. Scrollbars can also be applied to other types of axes.

Another approach to scrollable charts is the chart.scrollablePlotArea option that is especially suitable for simpler cartesian charts on mobile.

In styled mode, all the presentational options for the scrollbar are replaced by the classes `.highcharts-scrollbar-thumb`, `.highcharts-scrollbar-arrow`, `.highcharts-scrollbar-button`, `.highcharts-scrollbar-rifles` and `.highcharts-scrollbar-track`.
