# Gauge Types

## Content



[C1Gauge](/componentone/docs/xamarin/online-ios/) comprises of three kinds of gauges: [C1LinearGauge](/componentone/docs/xamarin/online-ios/), [C1RadialGauge](/componentone/docs/xamarin/online-ios/) and [C1BulletGraph](/componentone/docs/xamarin/online-ios/).

|   **Type**   |   **Image**   |   **Usage**   |
| --- | --- | --- |
| **Linear Gauge**: A linear gauge displays the value along a linear scale, using a linear pointer. The linear scale can be either horizontal or vertical, which can be set using the [Direction](/componentone/docs/xamarin/online-ios/) property. |   ![](https://cdn.mescius.io/document-site-files/images/1398d806-ac3c-4763-a9b3-2c7a2f5b49fb/images/lineargauge.png)   |   A linear gauge is commonly used to denote data as a scale value such as length, temperature, etc.   |
| **Radial Gauge**: A radial gauge displays the value along a circular scale, using a curved pointer. The scale can be rotated as defined by the [StartAngle](/componentone/docs/xamarin/online-ios/) and [SweepAngle](/componentone/docs/xamarin/online-ios/) properties. It also provides [IsReversed](/componentone/docs/xamarin/online-ios/) property to reorient the radial gauge so that it is drawn reversed (counter-clockwise). |   ![](https://cdn.mescius.io/document-site-files/images/1398d806-ac3c-4763-a9b3-2c7a2f5b49fb/images/radialgauge.png)![](https://cdn.mescius.io/document-site-files/images/1398d806-ac3c-4763-a9b3-2c7a2f5b49fb/images/radialguage_reversed.png)   |   A radial gauge is commonly used to denote data such as volume, velocity, etc.   |
| **Bullet Graph**: A bullet graph displays a single value on a linear scale, along with a target value and ranges that instantly indicate whether the value is good, bad or in some other state. |   ![](https://cdn.mescius.io/document-site-files/images/1398d806-ac3c-4763-a9b3-2c7a2f5b49fb/images/bulletgraph.png)   |   A bullet graph is a variant of a linear gauge, designed specifically for use in dashboards that display a number of single value data, such as yearly sales revenue.   |
