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 🙏

v1.0.59

散点图

Readme

@so-chart/point

基于 Canvas 绘制的散点图组件,支持数值、日期或映射 x 轴,交叉线、标签、Tooltip 和高频点位命中。

安装

pnpm add @so-chart/point

最小用法

下面示例假设 container 是承载图表的 HTMLElement:

import getPointChart, { type PointOptions } from '@so-chart/point';

const chart = getPointChart({
  container,
  chartType: 'point',
  layout: { height: 320 },
});

const options: PointOptions = {
  xAxis: { type: 'value', data: { start: 0, end: 3 } },
  yAxis: { type: 'value', data: { start: 0, end: 100 } },
  datasets: [{ label: 'Series', data: [20, 45, 80] }],
  tooltip: { show: true },
};

chart.setOption(options);

xAxis.type 也可以使用 date 或 mapping;cross 控制十字线与点提示,dotType、dotSize 和 dotColor 控制点样式。组件卸载或重新创建图表前,请调用 chart.dispose()。

CSP nonce 与类型

创建图表时可以传入 nonce。图表包不会生成 nonce,解析优先级为显式 nonce、宿主页面已有资源 nonce,最后兼容 globalThis.__CSP_NONCE__。

散点图选项和实例类型由包入口直接导出:

import getPointChart, { type PointOptions, type PointChartInstance } from '@so-chart/point';

示例与说明

  • 可运行示例:demo/examples
  • 配置与行为说明:demo/docs
  • 预览站和包独立 Demo 都从 demo/manifest.ts 读取示例关系;宿主接入仍以本 README、包入口和导出类型为准。
