HarmonyOS 能否提供一个demo，想实现柱状图且能控制是否滑动

通过@Provide和@Consume状态管理，在子组件内部捕捉TouchType.Down事件，关闭Tab滑动，让LineChart响应滑动；

滑动结束后恢复Tab的滑动属性，样例代码如下：

// 父组件内：
import { Const } from '../common/constants/CommonConstants';
import { MineWeightComponent } from '../view/MineWeightComponent';
@Entry
@Component
struct TabTest {
  @Provide tabScrollable: boolean = true
  build() {
    RelativeContainer() {
      Tabs() {
        TabContent() {
          Scroll() {
            MineWeightComponent()
          }
          .height(Const.FULL_PERCENT)
          .scrollBar(BarState.Off)
          .nestedScroll({
            scrollForward: NestedScrollMode.PARENT_FIRST,
            scrollBackward: NestedScrollMode.SELF_FIRST,
          })
        }
        .tabBar(this.tabBuilder(0, "TAB_1"))
      }
      // 绑定tabScrollable
      .scrollable(this.tabScrollable)
    }
    .height('100%')
    .width('100%')
  }
}
// 子组件内
@Component
export struct MineWeightComponent {
  @Consume tabScrollable: boolean
  //...
  build() {
    Column() {
      LineChart({ model: this.model })
        .width(FULL)
        .height(400)
        .onTouch((event: TouchEvent) => {
          // 通过不同事件，变更父组件Tab的滑动属性
          switch (event.type) {
            case TouchType.Down:
              this.tabScrollable = false
              break
            case TouchType.Cancel:
              this.tabScrollable = true
              break
            case TouchType.Up:
              this.tabScrollable = true
              break
          }
        })
  //...
}
  }
}
