# Parameter Controller

**Parameter Controller** is a component in input controllers for input control of multidimensional dataset parameters.

  For details on parameter creation, see [Parameters](../../../stories/parameter/).

## Input

The controller corresponding to **Input** type parameters is basically an input box, allowing users to manually enter values. If the parameter type is **Number**, you can also choose to use a slider to control parameter values. Slider detailed parameters are as follows:

| Name                   | Description                                                      |
| ---------------------- | ---------------------------------------------------------------- |
| Use Slider             | Whether to use slider component to display parameter value input |
| Slider Max Value       | Maximum value allowed by the slider                              |
| Slider Min Value       | Minimum value allowed by the slider                              |
| Slider Step Size       | Value change size produced by sliding the slider one step        |
| Slider Interval Length | Actual display length of slider scale intervals                  |
| Slider Inverted        | Display slider in reverse                                        |
| Slider Vertical        | Display slider vertically                                        |

## Selection

**Selection** type parameters will be displayed as a selection list of optional values. Optional list members will use the pre-entered value list in the parameters. Currently supports single selection.

## Dimension Members

**Dimension** type parameters are based on a given dimension, displaying pre-selected members as controller options. Users select one or more from these members as result values.
