+# Simple Bar Chart + Regression Line
+
+## Key Configuration
+
+By passing different configuration items to the `appendBarRegressionLineConfig` method, you can add multiple regression lines of different degrees and styles to the bar chart.
+
+- `degree`: The degree of the polynomial regression, e.g., 2 for quadratic, 3 for cubic.
+- `color`: The color of the regression line.
+- `line.style`: Style configuration for the regression line, such as `lineWidth` for line thickness.
+- `confidenceInterval.visible`: Whether to display the confidence interval (boolean).
+- `confidenceInterval.style`: Style configuration for the confidence interval, such as `fillOpacity` for opacity.
+- `label.text`: The label text for the regression line.
+

+# Histogram Regression Line
+
+## Key Information
+
+- Use `bin` binning to process raw data and generate the intervals and frequency data required for the histogram.
+- In the histogram configuration, you need to specify the following fields:
+  - `xField`: Represents the left endpoint of each interval (e.g., `x0`).
+  - `x2Field`: Represents the right endpoint of each interval (e.g., `x1`).
+  - `yField`: Represents the frequency of each interval (e.g., `frequency`).
+- You can add regression lines (such as KDE kernel density estimation and ECDF empirical cumulative distribution function) via extended configuration to help analyze the data distribution.
+
+## Code Example
+
+```javascript livedemo

+- Register the regression line extension using `registerRegressionLine()`

+- You can set the regression line type (`type: 'linear' | 'logistic' | 'lowess' | 'polynomial'`), color, degree (for polynomial), confidence interval style, label, and more

+# 简单柱图+回归线
+
+## 关键配置
+
+通过在 `appendBarRegressionLineConfig` 方法中传入不同的配置项，可以为柱图添加多条不同阶数和样式的回归线。
+
+- `degree`：多项式回归的阶数，如 2 表示二次多项式，3 表示三次多项式。
+- `color`：回归线的颜色。
+- `line.style`：回归线的样式配置，如 `lineWidth` 表示线宽。
+- `confidenceInterval.visible`：是否显示置信区间，布尔值。
+- `confidenceInterval.style`：置信区间的样式配置，如 `fillOpacity` 表示透明度。
+- `label.text`：回归线的标签文本。

+# 直方图回归线
+
+## 关键信息
+
+- 使用 `bin` 分箱对原始数据进行处理，生成直方图所需的区间和频率数据。
+- 直方图配置中需指定以下字段：
+  - `xField`：表示每个区间的左端点（如 `x0`）。
+  - `x2Field`：表示每个区间的右端点（如 `x1`）。
+  - `yField`：表示每个区间的频数（如 `frequency`）。
+- 可通过扩展配置添加回归线（如 KDE 核密度估计和 ECDF 经验累积分布函数）以辅助分析数据分布。
