# Customizing Line and Area Plots (Standard & Radar)

Learn how to customize Line and Area plots in ActiveReportsJS.

## Content

The following properties allow you to fine-tune the appearance of lines in  `Line and Area Plots`. You can experiment with these settings by modifying the configuration of any line or area plot demos.

## Line Aspect

The **Line Aspect** property defines the style of the line connecting data points:

* **Default** – A straight line connecting each data point.
* **Spline** – A smooth Bézier curve that flows through the data points.
* **Step Center**, **Step Left**, **Step Right** – A stepped line where changes occur at different positions along the step. These styles are useful for visualizing discrete changes. You can explore these options in the [Single Line Demo](https://developer.mescius.com/activereportsjs/demos/Reports/SingleLinePlot/purejs) to see their differences in action.


## Swapping Axes

Enabling the **Swap Axes** option flips the **Line Plot**, orienting the x-axis vertically instead of horizontally. This can be useful for specific data presentations where a vertical time series or category arrangement is preferred.

> type=warning
> The **Swap Axes** option is **not applicable** to **Radar Line Plots**, as these plots always arrange categories radially around a central point.
