In addition to major ticks, the PolarChart widget provides the capability to draw minor ticks. Minor ticks divide an axis segment that lies between two neighboring major ticks. To specify how to generate minor ticks, use the minorTickInterval or minorTickCount options.
To configure the appearance of minor ticks, use the options of the minorTick object. Declared within the commonAxisSettings object, the minorTick object sets options for all minor ticks. To change the appearance of the minor ticks that belong to the argument or value axis individually, declare the minorTick object in the argumentAxis or valueAxis object respectively. Settings specified individually override those that are set in the commonAxisSettings object.
By default, minor ticks are hidden. To make them visible, assign true to the visible option of the minorTick object. Additionally, you can change the color, opacity and width of the minor ticks using the corresponding options.
This option supports the following colors.
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
