uni app中使用图表

本文介绍: uni app,ucharts,echarts

关于在uni app中运用图表

今天写项目,需要在uni app中使用图表,我使用的是ucharts.

具体操作如下

1.下载

ucharts可以直接在uni app的插件市场下载安装.

先在插件市场下载ucharts,导入到自己要使用的图表的项目.

2.使用

先用在线生成工具生成自己想要的样式.

秋云uCharts图表组件

然后就是导入项目中,因为我一个页面要用很多不同的图表,所以我就把不同的图表给拆成不同的组件了.

在组件里面将刚刚在线生成的代码拷进去

最后就是把刚刚自己的样式配置给拷进去

3.展示

最后在自己的页面,引入组件就可以了

下面是我的组件代码

&lt;template&gt;
  &lt;view class="column-chart"&gt;
    <qiun-data-charts
        type="column"
        :chartData="chartData"
        :opts="opts"
        background="#FFFFFF"
    /&gt;
  </view&gt;
</template>

<script>
export default {
  name: "column-chart",
  data() {
    return {
      chartData: {
