ui.Chart.feature.groups
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
從一組特徵產生圖表。繪製特徵群組中指定屬性的值。具有相同 groupProperty 值的特徵會分組並繪製為單一序列。
- X 軸 = xProperty 值。
- Y 軸 = yProperty 值。
- 序列 = 特徵群組 (依 seriesProperty)。
傳回圖表。
| 用量 | 傳回 |
|---|
ui.Chart.feature.groups(features, xProperty, yProperty, seriesProperty) | ui.Chart |
| 引數 | 類型 | 詳細資料 |
|---|
features | Feature|FeatureCollection|List<Feature> | 要納入圖表的功能。 |
xProperty | 字串 | 做為 x 軸上每個特徵標籤的屬性。 |
yProperty | 字串 | 要在 Y 軸上繪製的屬性。 |
seriesProperty | 字串 | 用於判斷特徵群組的屬性。如果特徵的 groupProperty 值相同，系統會在圖表上繪製為單一序列。 |
