  ```

#### Usage
```js
const data = {
    labels: ["12am-3am", "3am-6pm", "6am-9am", "9am-12am",
        "12pm-3pm", "3pm-6pm", "6pm-9pm", "9am-12am"
    ],
    datasets: [
        {
            name: "Some Data", type: "bar",
            values: [25, 40, 30, 35, 8, 52, 17, -4]
        },
        {
            name: "Another Set", type: "line",
            values: [25, 50, -10, 15, 18, 32, 27, 14]

}

const chart = new frappe.Chart("#chart", {  // or a DOM element,
                                            // new Chart() in case of ES6 module with above usage
    title: "My Awesome Chart",
    data: data,
    type: 'axis-mixed', // or 'bar', 'line', 'scatter', 'pie', 'percentage'

+ const chart = new Chart("#chart", {  // or a DOM element,
                                    // new Chart() in case of ES6 module with above usage
    title: "My Awesome Chart",
    data: data,
    type: 'axis-mixed', // or 'bar', 'line', 'scatter', 'pie', 'percentage'
    height: 250,
    colors: ['#7cd6fd', '#743ee2']
