For those having the same issue, the map is correctly displayed when using this code :
import europe from '@assets/mapData/europe.json';
import { topojson, IGeoDataPoint, ChoroplethChart } from 'chartjs-chart-geo';
const canvas = ref<HTMLCanvasElement | undefined>();
const states = (topojson.feature(europe as any, europe.objects.europe as any) as any).features;
const config = ref<ChartConfiguration<'choropleth', IGeoDataPoint[], string[]>>({
type: 'choropleth',
data: {
labels: states.map((d : any) => d.properties.NAME),
datasets: [{
label: "Europe",
data: states.map((d : any) => ({feature: d, value: Math.random() * 10})),
}]
},
options: {
plugins: {
legend: {
display: false
},
},
showGraticule: true,
scales: {
projection: {
axis: 'x',
projection: 'mercator',
projectionScale: 7,
},
color: {
axis: 'x',
quantize: 5,
legend: {
position: 'bottom-right',
align: 'bottom'
},
}
},
}
});
onMounted(() => {
if (canvas.value) new ChoroplethChart(canvas.value, config.value);
});
So data is correct, it was just a bad parsing of the data I think :)
