javascript - datasets - Gráfico de dona Chartjs con color degradado

line chart options chart js

Question

Creé un gráfico de dona. ¿Hay alguna posibilidad de hacer esos colores como gradiente? Vi esta publicación , traté de implementarla en mi propia tabla pero no pude.

Cualquier ayuda, lo agradeceré.

var ctx = $(''#teamDoughnutChart'');
var doughnutBar = new Chart(ctx, {
type: ''doughnut'',
data: {
labels: ["A", "B", "C", "D", "E"],
datasets: [{
label: "Status",
backgroundColor: [
''rgba(192, 57, 43,1)'',
''rgba(244, 187, 18, 1)'',
''rgba(41, 128, 185,1)'',
''rgba(39, 174, 96,1)'',
''rgba(191, 199, 215, 1)''
],
borderColor: ''rgba(73, 79, 92, 0)'',
data: [24, 38, 96, 79, 41]
}]
},
options: {
cutoutPercentage: 70,
maintainAspectRatio: false,
startAngle: 0,
tooltips: {
mode: ''index'',
backgroundColor: ''#393e48''
},
legend: {
position: ''bottom'',
labels: {
fontSize: 12,
padding: 25,
boxWidth: 15
}
}
}
});

Tengo el mismo problema. Encontré solución. Prueba esto

var canvas = $(''#teamDoughnutChart'');
var ctx = canvas.getContext(''2d'');
var gradientColors = [
{
start: ''#f3bb98'',
end: ''#ea8ba9''
},
{
start: ''#F6A064'',
end: ''#ED5384''
}
];
var gradients = [];
gradientColors.forEach( function( item ){
var gradient = ctx.createLinearGradient(0, 0, 150 , 150);
gradient.addColorStop(0, item.start);
gradient.addColorStop(1, item.end);
gradients.push(gradient);
});
var doughnutBar = new Chart(canvas, {
type: ''doughnut'',
data: {
labels: ["A", "B"],
datasets: [{
label: "Status",
backgroundColor: gradients,
borderColor: ''rgba(73, 79, 92, 0)'',
data: [24, 38]
}]
},
options: {
cutoutPercentage: 70,
maintainAspectRatio: false,
startAngle: 0,
tooltips: {
mode: ''index'',
backgroundColor: ''#393e48''
},
legend: {
position: ''bottom'',
labels: {
fontSize: 12,
padding: 25,
boxWidth: 15
}
}
}
});
