How to reuse a Chart.js chart in Blazor wasm? I got the error message to destroy the canvas before reuseing. I read this topic: Destroy chart.js bar graph to redraw other graph in same <canvas> But none of these answers solved my problem. This is my method to invoke the JavaScript of Chart.js
await JSRuntime.InvokeVoidAsync("setup", Id, config);
window.setup = (id, config) => {
var ctx = document.getElementById(id).getContext('2d');
new Chart(ctx, config);
}
How can I implement a working .destroy() call in the method, or how can I update the chart?
Got it:
window.setup = (id, config) => {
var myChart = Chart.getChart(id);
if (myChart != undefined) {
myChart.destroy();
}
var ctx = document.getElementById(id).getContext('2d');
new Chart(ctx, config);
console.log(config);
}
(First it was not working for reasons of the browsers cache)
