14 Apr 2021 / 8 minutes to read

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.

      </AxisDirective>
    </AxesDirective>
  </CircularGaugeComponent>, document.getElementById('circulargauge'));

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.

The direction property enables you to render the gauge axis either in ClockWise or in AntiClockWise direction.

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,

    </AxesDirective>
  </CircularGaugeComponent>, document.getElementById('circulargauge'));

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 ticks 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.

The following table describes the result of applying some commonly used label formats on numeric values.

Label Value	Label Format property value	Result	Description

1000	n2	1000.00	The Number is rounded to 2 decimal place
1000	n3	1000.000	The Number is rounded to 3 decimal place
0.01	p1	1.0%	The Number is converted to percentage with 1 decimal place
0.01	p2	1.00%	The Number is converted to percentage with 2 decimal place
0.01	p3	1.000%	The Number is converted to percentage with 3 decimal place
1000	c1	0. ,000.0	The Currency symbol is appended to number and number is rounded to 1 decimal place
1000	c2	0. ,000.00	The Currency symbol is appended to number and number is rounded to 2 decimal place

Custom Label Format

Axis labels support custom label format using placeholder like {value}°C, in which the value represent the axis label e.g 20°C.
