hHw自定义简易饼图栏

Question

如何在简易饼图中自定义条形尺寸/比例尺寸？我这样做但我需要更多细条。我自定义百分比和其他选项，但无法找到自定义条形的方法。

HTML：

 <div class="row">
        <div class="pie-chart-area"><!-- pie-chart-area-start-->
            <div class="col-md-2" >
                <span class="chart" data-percent="75">
                <span class="percent"></span>
                </span>
                <h1>web design</h1>
            </div>
            <div class="col-md-2" >
                <span class="chart" data-percent="92">
                <span class="percent"></span>
                </span>
                <h1>web development</h1>
            </div>
            <div class="col-md-2" >
                <span class="chart" data-percent="68">
                <span class="percent"></span>
                </span>
                <h1>speed optimization</h1>
            </div>
            <div class="col-md-2" >
                <span class="chart" data-percent="100">
                <span class="percent"></span>
                </span>
                <h1>customer support</h1>
            </div>
            <div class="col-md-2" >
                <span class="chart" data-percent="83">
