Axes

By default, gauge will be displayed with an axis. Each axis contains its own ranges, pointers and annotation.

Axis Customization

You can customize the width and color of an axis line by using lineStyle property. Background for an axis can be customized by using background property.

Angles and Direction

Circular gauge axis can sweep from 0 to 360 degrees. By default start angle of an axis is 200 degree and end angle is 160 degree and you can customize this option by using startAngle and endAngle property.

Axis Radius

By default, radius of an axis is calculated based on the available size. You can customize this, by using radius property. It takes value either in percentage or in pixel.

In Pixel

You can set the radius of the gauge in pixel as demonstrated below,

In Percentage

By setting value in percentage, gauge gets its dimension with respect to its available size. For example, when the radius is ‘50%’, gauge renders to half of the available size.

Ticks

You can customize the height, color and width of major and minor ticks by using majorTicks and minorTicks property. By default, interval for majorTicks will be calculated automatically and also you can customize the interval for major and minor ticks using interval property.

Tick Position

Both minor and major ticks can be moved by using offset and position property. The offset defines the distance between the axis and ticks. By default, offset value is 0. The position will place the ticks either inside or outside of the axis.

By default, ticks will be placed inside the axis.

Smart Labels

When an axis makes a complete circle, then the first and last label of the axis will get overlap with each other. In this scenario, you can either hide 1st or last label using hiddenLabel property. When hiddenLabel value is First, then the 1st label will be hidden and when the hiddenLabel value is ‘Last’, then the last label will be hidden.
