Current and expected behavior
I am making a stacked bar chart with label text is replaced with image but my handleDrawImage runs multiple times in the first-time component render and hovering to display tooltip that causing performance issue
const handleDrawImage = (chart: ChartJS) => {
const { ctx } = chart;
const dataLength = plans ? plans.length : 0;
const chartHeight = chart.chartArea.height;
const step = (chartHeight - barSize * dataLength) / dataLength;
const yOffset = 30;
ctx.save();
plans?.forEach((item, i) => {
let newImage = new Image();
newImage.src = "Image source here";
const imageY = i * (barSize + step) + yOffset;
ctx.drawImage(newImage, 0, imageY, 30, 30);
});
ctx.restore();
};
return (
<div className="col-span-9">
<div className="w-full flex items-center justify-center">
<Bar
data={data}
height={400}
options={chartOptions}
redraw={true}
plugins={[
{
id: 'sectorBackground',
afterDraw: (chart) => handleDrawImage(chart),
},
ChartDataLabels,
]}
/>
</div>
</div>
);
