Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

igroot-charts 图表库

详情

使用方法:

npm install igroot-charts --save

然后在想要引入的界面里 import { Line } from 'igroot-charts' 可选的图表:

  • Line:折线图
  • Pie:饼图
  • Scatter:散点图
  • Bar:柱状图
  • MixChart 混合图

折线图

<Line
  id={"line"}
  title={"lineTitle"} /* 非必填 */
  legend={true} /* 非必填 */
  xAxis={['周一', '周二', '周三', '周四', '周五', '周六', '周日']}
  click={this.fun}
  data={[
    {
      name: 'line1',
      data: [120, 132, 101, 134, 90, 230, 210]
    },
    {
      name: 'line2',
      data: [134, 90, 230, 210, 120, 132, 101]
    }
  ]}
  settings={lineOption}
/>

柱状图

<Bar
  id={"bar"}
  title={"title1"}
  legend={true}
  xAxis={['周一', '周二', '周三', '周四', '周五', '周六', '周日']}
  data={[
    {
      name: 'mmm',
      data: [110, 112, 101, 134, 90, 230, 210],
    }
  ]}
  settings={barOption}
/>

散点图

<Scatter
  id={"scatter"}
  title={"Scatter"}
  legend={true}
  xAxis={['周一', '周二', '周三', '周四', '周五', '周六', '周日']}
  data={[
    {
      // id:'bar1',
      name: 'cnm',
      data: [['周二', 20, 30], ['周一', 10, 30], ['周三', 30, 30]],
    }
  ]}
  settings={scatterOption}
/>

饼图

<Pie
  id={"pie"}
  title={"title1"}
  legend={true}
  radius = {['40%', '55%']}
  data={[
    {
      name: 'aaa',
      data: '120'
    },
    {
      name: 'bbb',
      data: '132'
    },
    {
      name: 'ccc',
      data: '150'
    },
  ]}
  settings={pieOption}
/>

  • 以上图表都只适合单图的简单场景,如需混合显示,请使用混合组件,使用方法copy echarts配置项,自己更改数据部分即可

混合组件

<MixChart 
  id = "aaasss"
  legendselectchanged= {this.getMixChart.bind(this,"SSS")} <!-- 图例变更事件 -->
  notMerge={false}
  style={{
    width: '800px',
    height: '500px'
  }}
  settings={
    <!-- echarts 配置项 -->
  }
/>

这个是完全遵守echarts规则的配置方案,直接拷贝echarts配置项在option属性即可。

事件与交互:

  • 支持的事件有
    'click': true,    <!-- 常用 -->
    'legendselectchanged': true,    <!-- 常用 -->
    'legendselected': true,
    'legendunselected': true,
    'datarangeselected': true,
    'timelinechanged': true,
    'timelinechanged': true,
    'restore': true,
    'geoselectchanged': true,
    'geoselected': true,
    'geounselected': true,
    'pieselectchanged': true,
    'pieselected': true,
    'mapselectchanged': true,
    'mapselected': true,
    'mapunselected': true,
    'axisareaselected': true,
    'focusnodeadjacency': true,
    'unfocusnodeadjacency': true,
    'brush': true,
    'brushselected': true

鼠标事件的参数如下

{
  // 当前点击的图形元素所属的组件名称,
  // 其值如 'series'、'markLine'、'markPoint'、'timeLine' 等。
  componentType: string,
  // 系列类型。值可能为:'line'、'bar'、'pie' 等。当 componentType 为 'series' 时有意义。
  seriesType: string,
  // 系列在传入的 option.series 中的 index。当 componentType 为 'series' 时有意义。
  seriesIndex: number,
  // 系列名称。当 componentType 为 'series' 时有意义。
  seriesName: string,
  // 数据名,类目名
  name: string,
  // 数据在传入的 data 数组中的 index
  dataIndex: number,
  // 传入的原始数据项
  data: Object,
  // sankey、graph 等图表同时含有 nodeData 和 edgeData 两种 data,
  // dataType 的值会是 'node' 或者 'edge',表示当前点击在 node 还是 edge 上。
  // 其他大部分图表中只有一种 data,dataType 无意义。
  dataType: string,
  // 传入的数据值
  value: number|Array
  // 数据图形的颜色。当 componentType 为 'series' 时有意义。
  color: string
}

总结:

igroot-charts为你做了什么

  • 组件除了混合组件外抽象出数据层,和一些数据相关的配置,配置数据到属性直接在图表中体现,

  • 并且所有组件已经为您做好了动态加载,在组件内部即已经处理,无需import 各个配置项的模块,也不依赖项目中的任何其他图表库,尽可能提升了性能

  • 事件系统:通过 click 等 很直观的使用方法,即可触发事件,并且可以很容易传递自定义参数,

  • MixCharts 混合组件的意义在于多个混合图标混合使用时可满足所有使用场景,但使用方法需要配置echarts配置项到 settings属性。

  • 定制主题 用法:下载echarts主题,找到文件里

echarts.registerTheme(*infographic*, 

把 'infographic' 字符串写到 theme 属性里
