JavaScript/jQuery Chart - series.hoverStyle

Declared in commonSeriesSettings, hoverStyle applies to all series in the chart. Declared in a series configuration object, hoverStyle applies to this particular series only. The series-specific hoverStyle overrides the common one.

This property supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors
• Paint server address

You can also specify a custom pattern or gradient instead of a plain color. Call the registerPattern() or registerGradient() method to obtain a fill ID. Assign that value to the fillId field.

This functionality is available for the following Chart series:

• Area
• Stacked area
• Full-stacked area
• Spline area
• Stacked spline area
• Full-stacked spline area
• Range area
• Step area
• Bar
