map组件规划路径在地图中显示不全？

<map id="addressMap" include-points="{{markers}}" bindregionchange="regionchange" enable-zoom="{{true}}"

polyline="{{polyline}}" markers="{{markers}}" longitude="{{longitude}}" latitude="{{latitude}}" scale='14' style="position:relative;width:100%;height:200px">

wx.createMapContext('addressMap').includePoints({

padding: [50, 50, 50, 50],

points: markers

})

scale设置缩放，可以缩放的呢
