Note: For the demo we have used timeouts to help mimic API calls or promises.

You will use ZingCharts api method modify  to update the chart noData  display text. 

// myChart is the id of the chart   
zingchart.exec('myChart', 'modify', {
  data: {
    noData: {
      text: 'Downloading data from server...'
    }
  }
});
