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 🙏

简介

autocharts.js 可以帮助你在不规范的数据中找出可用于 echarts 的数据,并返回符合echarts要求的基本格式。

目前 它仅支持两种 数据格式:

格式一:数组成员为包含x、y轴对应数据的对象

type objInArr {
	xKey:string;
	yKey:number;
}
Array<objInArr>
// 例如
// const objInArr = [
//	{
//   name:"xAxisName",
//   value:100 
//	},...
//]

格式二:对象内包含多个长度一致的数组(推荐)

type standobj {
	xKey:Array<string | number>,
	yKey1:Array<number>,
	yKey2:Array<number>
}

安装

npm i autocharts.js

使用示例

import findChartData from 'autocharts.js'
let autoData = autoCharts.findChartData({
     rawData: yourData,
     xKey: "col3",
     yKey: "levelCount",
     type: "pie",
});

对于 objInArr 格式数据需传入 xKey && yKeystandobj 格式数据可以不传入xKey || yKey ,但要求该对象内有两个或以上长度一致的数组,autocharts可以自动找出这些数组并按照数据类型将他们分为x、y轴数据,建议把数据处理成standobj格式后再使用。

返回的基本格式:

{
    "xAxis": {
        "type": "category",
        "data": [
            "重旱",
            "中旱",
            "轻旱",
            "适宜",
            "过湿"
        ]
    },
    "series": {
        "type": "pie",
        "data": [
            {
                "value": 6816,
                "name": "重旱"
            },
            {
                "value": 317696,
                "name": "中旱"
            },
            {
                "value": 124228,
                "name": "轻旱"
            },
            {
                "value": 8811,
                "name": "适宜"
            },
            {
                "value": 2400,
                "name": "过湿"
            }
        ]
    },
    "legend": {
        "data": [
            "重旱",
            "中旱",
            "轻旱",
            "适宜",
            "过湿"
        ]
    }
}
