Answer 1

Here's an example to redraw the chart with random numbers whenever the button is clicked. Hopefully this will give you enough to work your example:

var svg = dimple.newSvg("#chartContainer", 590, 400);
var data = [
    { Animal: "Cats", Value: (Math.random() * 1000000) },
    { Animal: "Dogs", Value: (Math.random() * 1000000) },
    { Animal: "Mice", Value: (Math.random() * 1000000) }
];

var myChart = new dimple.chart(svg, data);
myChart.setBounds(60, 30, 510, 305)
var x = myChart.addCategoryAxis("x", "Animal"); 
x.addOrderRule(["Cats", "Dogs", "Mice"]);
myChart.addMeasureAxis("y", "Value");
myChart.addSeries(null, dimple.plot.bar);
myChart.draw();

d3.select("#btn").on("click", function() {
    myChart.data = [
        { Animal: "Cats", Value: (Math.random() * 1000000) },
        { Animal: "Dogs", Value: (Math.random() * 1000000) },
        { Animal: "Mice", Value: (Math.random() * 1000000) }
    ];
    myChart.draw(1000);
});
