Angular LinearGauge - valueIndicator

The value indicator is a pointer that designates the main value of the gauge. There are several types of value indicators. Set the required one by using the type property, and then specify the properties that are specific to this type, if needed. To learn about the properties that can be specified for a particular type, refer to one of the following sections.

• Circle
• RangeBar
• Rectangle
• Rhombus
• TextCloud
• TriangleMarker

This property supports the following colors:

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

By default, a range bar starts from the beginning of the gauge scale. If you need to draw the range bar starting from a specific scale value, assign the required value to the baseValue property. In this instance, the range bar will display the range from the baseValue to the main gauge value.

When adapting, the indicator adjusts its parts and surroundings proportionally to the changing UI component size. The adjustments affect the incidator's indent from the center, the offset from the scale, and the spindle's size and gap.

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.

$(function(){
    $("#linearGaugeContainer").dxLinearGauge({
        // ...

                fillId: customPatternId
            }
        }
    });

                fillId: this.customPatternId
            }
        }
    }
}

import DxLinearGauge, { DxValueIndicator } from 'devextreme-vue/linear-gauge'; 
// ...

const fill = {
    fillId: customPatternId
};
</script>

import React from 'react';
import LinearGauge, { ValueIndicator } from 'devextreme-react/linear-gauge';

// ...
const fill = {
    fillId: customPatternId

export default function App() { 
    return ( 
        <LinearGauge ... >
            <ValueIndicator color={fill} />
        </LinearGauge>        
    ); 
} 

This property specifies the orientation of the indicator relative to an invisible scale line.

When you use a twoColorNeedle indicator, define the colors for it using the color and secondColor properties. The color property sets the color for the base of the needle. The secondColor property sets the color for the tip of the needle.

This property supports the following colors:

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

In addition, you can specify the ratio between the main and the second color using the secondFraction property.

Set this property to 0 so that the spindle has the shape of a circle.

Note that the indent property of the text configuration object must not be set to 0 if you need to show the text.

Different properties of the valueIndicator configuration object can be set for different types of the value indicator. These properties are listed within the Indicator Types section.
