yes there is no default export:
https://github.com/sgratzl/chartjs-chart-geo/blob/main/src/index.ts
not sure how you import the library
from chartjs-chart-geo.
i imported just like documentation
import { Chart , registerables} from 'chart.js'; import { ChoroplethController, GeoFeature, ColorScale, ProjectionScale } from 'chartjs-chart-geo'; Chart.register(ChoroplethController, GeoFeature, ColorScale, ProjectionScale);
im dont know how to use map. the documentation said
fetch('https://unpkg.com/world-atlas/countries-50m.json').then((r) => r.json()).then((data) => { const countries = ChartGeo.topojson.feature(data, data.objects.countries).features;
but where is ChartGeo. can you please show me a full example with using npm imports way. the codepen examples doesnt suite my project
from chartjs-chart-geo.
i should have import topojson as wall to implement map. the complete code is below
import map from 'world-atlas/countries-50m.json';
import { topojson, ChoroplethController, GeoFeature, ColorScale, ProjectionScale } from 'chartjs-chart-geo';
Chart.register(ChoroplethController, GeoFeature, ColorScale, ProjectionScale);
const countries = topojson.feature(map, map.objects.countries).features;
const chart = new Chart(document.getElementById("myChart").getContext("2d"), {
type: 'choropleth',
data: {
labels: countries.map((d) => d.properties.name),
datasets: [{
label: 'Countries',
data:countries.map((d) => ({feature: d, value: d.value}))
}]
},
options: {
showOutline: true,
showGraticule: false,
plugins: {
legend: {
display: false
},
},
scales: {
projection: { axis: 'x', projection: 'equirectangular' } } } })
from chartjs-chart-geo.
