🥰 [FEATURE]堆叠柱状图区域连接组件里面的triggerOn参数，希望能像1.0版本一样设定一个false，默认展示所有区域的联通效果。现在2.0版本无法设置默认展示联通效果。

### 🥰 Features description [Please make everyone to understand it]

### 🏞 What problem does this feature solve

### 🧐 What does the proposed API look like

### 🚑 Any additional [like screenshots]

Compare the stacked bar chart region connection component's triggerOn behavior in versions 1.0 and 2.0, starting from the component and its public API. Confirm that false is accepted and that the default displays connections for all regions; done means the 2.0 behavior matches the requested 1.0 behavior.
