# Secondary Y-Axis

The **Secondary Y-Axis** provides an additional vertical axis on the right side of the chart. It is particularly useful when displaying multiple data series that require different scales. The settings allow users to configure its visibility, position, labels, ticks, and range to optimize data visualization.

**Features & Descriptions**

| Feature      | Description                                                                                                                                                 |
| ------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Show**     | Enables or disables the visibility of the Secondary Y-axis. When checked, the axis appears on the chart.                                                    |
| **Inverse**  | Reverses the direction of the axis, displaying values in descending order.                                                                                  |
| **Type**     | Defines the data type for the axis. Options include `value` (numerical), `category` (discrete values), `time` (dates/times), and `log` (logarithmic scale). |
| **Position** | Determines whether the Secondary Y-axis appears on the `left` or `right` side of the chart. Typically, it is placed on the `right`.                         |
| **Name**     | Sets a label for the Secondary Y-axis to provide context for the displayed values.                                                                          |

| **Min & Max** | Allows users to manually define the minimum and maximum values of the Secondary Y-axis. If left empty, the system automatically adjusts based on the dataset. |

This configuration enables effective control over the Secondary Y-Axis, allowing users to display multiple scales in a single chart for enhanced comparative analysis.
