   如果在微信小程序，可以劫持touchMove事件，设置四周边界，但是不完美，强行移动也会导致无法拖回
   `javascript
       touchMove(e) {
         const chart = this.chart;
         const needGesture = this.data.needGesture;
         const len = e.touches.length;
         const width = this.chart.getWidth();
         const height = this.chart.getHeight();
         const boundary = {
           top: 0,
           left: 0,
           right: width,
           bottom: height,
         };
         if (chart && len > 0) {
           const touch = e.touches[0];
           const handler = chart.getZr().handler;
           const { x, y } = touch;
           if (boundary.top > x || boundary.bottom < x || boundary.right < y || boundary.left > y) {
             return;
           }
           if (needGesture && len === TOUCH_POINT_NUM) {
             handler.processGesture(wrapTouch(e), 'change');
             return;
           }
           handler.dispatch('mousemove', {
             zrX: touch.x,
             zrY: touch.y,
             preventDefault: () => {},
             stopImmediatePropagation: () => {},
             stopPropagation: () => {},
           });
         }
       },
   `
