Colors

You can also pass a object. You will need to create this before passing to the chart, but using it you can achieve some interesting effects.

For example, if you wanted to fill a dataset with a pattern from an image you could do the following.

Using the Patternomaly library you can generate patterns to fill datasets.

var chartData = {
    datasets: [{
        backgroundColor: [
            pattern.draw('square', '#ff6384'),
            pattern.draw('circle', '#36a2eb'),
            pattern.draw('triangle', '#ffce56'),
        ]
    }],
};
