New `options.resolve` helper that determines the final value to use from an array of input values (fallback) and a given context and/or index. For now, only the bubble chart support scriptable options, see documentation for details. Add scriptable options documentation and update the bubble chart dataset properties table with their scriptable and indexable capabilities and default values. Also move point style description under the element configuration section. |

Chart.js
Installation
You can download the latest version of Chart.js from the GitHub releases or use a Chart.js CDN. Detailed installation instructions can be found on the installation page.
Creating a Chart
It's easy to get started with Chart.js. All that's required is the script included in your page along with a single <canvas>
node to render the chart.
In this example, we create a bar chart for a single dataset and render that in our page. You can see all the ways to use Chart.js in the usage documentation
<canvas id="myChart" width="400" height="400"></canvas>
<script>
var ctx = document.getElementById("myChart").getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',

'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
