How can I export some graphics as an image?

trading-peter commented 6 years ago

Each chart element has chart property that holds a reference to the chartjs instance. So, according to http://www.chartjs.org/docs/latest/developers/api.html#tobase64image you can do the following:

const yourChartElement = document.querySelector('chart-pie');
const pngDataUrl = yourChartElement.chart.toBase64Image();
