If you are using this directive https://jtblin.github.io/angular-chart.js/, try the following:
this.color = [
{ backgroundColor: [
'#DCDCDC', // light grey
'#F7464A', // red
'#46BFBD', // green
]};
This is from code review of the directive’s convertColor and get color functions.
Line 238:
function convertColor (color) {
if (typeof color === 'object' && color !== null) return color;
if (typeof color === 'string' && color[0] === '#') return getColor(hexToRgb(color.substr(1)));
return getRandomColor();
}
Line 249:
function getColor (color) {
return {
backgroundColor: rgba(color, 0.2),
...
};`
}
And ChartJS’s bar graph sample (http://www.chartjs.org/docs/#bar-chart-data-structure).
var data = {
...
datasets: [
{
...
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
...
}
]
};
(And possibly an unwarranted hunch.)
