var Charts = function Charts(opts) {
  ...
  // this.context = wx.createCanvasContext(opts.canvasId); 为解决组件内不显示问题，替换为以下代码
  this.context = opts.that ? wx.createCanvasContext(opts.canvasId, opts.that) : wx.createCanvasContext(opts.canvasId);
  ...
}

new wxCharts({
  ...
  that: this  // 传递组件的this上下文
});
