需求描述

如果加载图表数据过多的时候，我们想定位到某根K线或者定位到某片区域，拖动会比较麻烦耗时
希望提供一个设置可见范围setVisibleRange的api
定位一片区域：setVisibleRange(leftbar,rightbar)
定位一根bar并居中，setVisibleRange(middlebar)

具体实现

希望提供一个设置可见范围setVisibleRange的api
定位一片区域：setVisibleRange(leftbar,rightbar) ，定位后直接只显示区域中的bar
定位一根bar并居中，setVisibleRange(middlebar)，定位后不放大缩小，将bar显示居中即可，可以先计算下当前区域范围bar的数量，重新生成新的区域范围并设置。（这个可加可不加）
