I was tring to add dotted pattern to the world map...using highmaps and pattern-fill.js. On doing that i gives a a basic maps with no color.
I used the following template for the same... Help me get it right.
The goal is to get a world continent map where all the continents are pattern filled and the pattern is like the following:
(async () => {
const topology = await fetch(
'https://code.highcharts.com/mapdata/custom/world-continents.topo.json'
).then(response => response.json());
// Prepare demo data. The data is joined to map using value of 'hc-key'
// property by default. See API docs for 'joinBy' for more info on linking
// data and map.
const data = [
['eu', 10],
['oc', 11],
['af', 12],
['as', 13],
['na', 14],
['sa', 15]
];
// Create the chart
Highcharts.mapChart('container', {
chart: {
type: 'map',
map: topology
},
title: {
text: 'Highcharts Maps basic demo'
},
subtitle: {
text: 'Source map: <a href="http://code.highcharts.com/mapdata/custom/world-continents.topo.json">World continents</a>'
},
mapNavigation: {
enabled: true,
buttonOptions: {
verticalAlign: 'bottom'
}
},
colorAxis: {
min: 0
},
plotOptions: {
series: {
type: "map",
color: {
pattern: {
path: {
d: 'M 3 3 L 8 3 L 8 8 Z',
fill: '#102045'
},
width: 12,
height: 12,
color: '#907000',
opacity: 0.5
}
}
}
},
series: [{
data: data,
name: 'Random data',
color: 'red',
dataLabels: {
enabled: true,
format: '{point.name}'
}
}]
});
})();Your color settings in plotOptions is overwritten by color in series options. You need to specify color in one of the places.
plotOptions: {
series: {
type: "map",
color: {
pattern: {
path: {
d: 'M 5 5 m -4 0 a 4 4 0 1 1 8 0 a 4 4 0 1 1 -8 0',
fill: 'red'
},
patternTransform: 'rotate(20)',
width: 12,
height: 12,
color: 'red'
}
}
}
}
