Tagged: #CanvasJS #pieChart #react
the Pie chart is not re-rendering, I can see the updated values when I hover on it but the chart is still the same.
it is working with the Class component, but not working on the Functional component
In order to render the chart with updated options (data), you need to use the render method after updating the chart options. To access ref attributes in react, you need to use chart.current.chart. Please take a look at this react documentation for more information.
Please take a look at this updated StackBlitz example.
