ui.Chart.feature.groups
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
根据一组特征生成图表。绘制给定属性在各特征组中的值。具有相同 groupProperty 值的要素将被分组并绘制为单个序列。
- X 轴 = xProperty 值。
- Y 轴 = yProperty 值。
- Series = 特征组，按 seriesProperty。
返回图表。
| 用法 | 返回 |
|---|
ui.Chart.feature.groups(features, xProperty, yProperty, seriesProperty) | ui.Chart |
| 参数 | 类型 | 详细信息 |
|---|
features | Feature|FeatureCollection|List<Feature> | 图表中要包含的特征。 |
xProperty | 字符串 | 用作 x 轴上每个特征标签的属性。 |
yProperty | 字符串 | 要在 y 轴上绘制的属性。 |
seriesProperty | 字符串 | 用于确定特征组的属性。具有相同 groupProperty 值的要素将在图表上绘制为单个序列。 |
