js动画线系列动画

Dimple.JS Animate line series animation

本文关键字：动画 系列 js      更新时间：2023-09-26

我试图使用Dimple.js实现图表，下面是我试图分别动画两个系列(条和线在这里)的代码，但它看起来像线系列动画像条系列(从下到上)。然而，我期待更像动画执行在这里:http://bl.ocks.org/duopixel/4063326

<div id="divBarWithLineChart" class="DimpleChart"></div>

    var width = $('#divBarWithLineChart').width();
    var height = $('#divBarWithLineChart').height();
    var svg = dimple.newSvg("#divBarWithLineChart", width - 20, height);
    d3.json("Scripts/Data/Data.json", function (data) {
        // Filter the data for a single channel
        data = dimple.filterData(data, "Channel", "Hypermarkets");
        // Create the chart
        var myChart = new dimple.chart(svg, data);
        myChart.setBounds(60, 30, 470, 300)
        // Add an x and 2 y-axes.  When using multiple axes it's
        // important to assign them to variables to pass to the series
        var x = myChart.addCategoryAxis("x", "Brand");
        var y1 = myChart.addMeasureAxis("y", "Price");
        var y2 = myChart.addMeasureAxis("y", "Sales Value");
        // Order the x axis by sales value desc
        x.addOrderRule("Sales Value", true);
        // Color the sales bars to be highly transparent
        myChart.assignColor("Sales", "#222222", "#000000", 0.1);
        // Add the bars mapped to the second y axis
        myChart.addSeries("Sales", dimple.plot.bar, [x, y2]);
        // Add series for minimum, average and maximum price
        var min = myChart.addSeries("Min", dimple.plot.line, [x, y1]);
        min.aggregate = dimple.aggregateMethod.min;
        myChart.setMargins("70px", "30px", "70px", "70px");
        myChart.assignColor("Sales", "#083f65", "#083f65", 1);
        myChart.assignColor("Min", "#c62828", "#c62828", 1);
        myChart.staggerDraw = true;
        myChart.ease = "bounce";
        myChart.draw(1000);

可以单独动画线条系列吗?有人能帮忙吗?

这是可能的。如果你在chrome开发者栏中检查svg行，它是一个svg路径，可以用css动画…路径类名是dimple-line。因此，只需添加一点css为这个类名，当线绘制时，它模仿d3的例子完全(在我的网站http://dimplejs.org尝试过)，它的工作完美…

<style>
    .dimple-line {
        stroke-dasharray: 1000;
        stroke-dashoffset: 1000;
        animation: dash 5s linear forwards;
    }
    @keyframes dash {
        to {
            stroke-dashoffset: 0;
        }
    }
</style>

或虚线效果试试这个…

.dimple-line {
        stroke-dasharray: 20;
        stroke-dashoffset: 1000;
        animation: dash 5s linear forwards;
    }
    @keyframes dash {
        to {
            stroke-dashoffset: 0;
        }
    }
