The scroll bar allows a user to pan the chart. To use it, you need to enable zooming and panning in your chart.
By default, the scroll bar is hidden. To make it visible, set the visible field of the scrollBar object to true. Using other fields of this object you can adjust the scroll bar appearance settings, including color, width and opacity.
This option supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
Depending on whether the chart is rotated or not, this option accepts different values. In a non-rotated chart, you can assign either 'top' or 'bottom' to this option. In a rotated chart, this option accepts either 'left' or 'right'.
