ui.Chart.feature.byFeature
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。绘制每个特征的一个或多个属性的值:
- X 轴 = 由 xProperty 标记的特征(默认值:'system:index')。
- Y 轴 = yProperties 的值(默认值:所有属性)。
- Series = yProperties 的名称。
这些值沿 x 轴按与输入特征相同的顺序排列。
返回图表。
用法 | 返回 |
---|
ui.Chart.feature.byFeature(features, xProperty, yProperties) | 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,可选 | 用作 x 轴上每个特征的值的属性。默认为“system:index”。 |
yProperties | List<String>|String,可选 | Y 轴上使用的属性。如果省略,则所有功能的所有属性都将绘制在 y 轴上(xProperty 除外)。 |
