Line Chart

Trends

"How did this move over time, and where can't I trust the data?" One series or fifty, with missing periods rendered as dashes so a reporting gap never reads as a real dip - plus an opt-in canvas renderer (LTTB-decimated for big data) when the points run into the thousands.

Example

canvas · responsive

The chart above is the same engine in every framework - only the integration code below differs.

Gap detection

A missing period renders as a dashed segment - set it per point with certainty: false, or let detectGaps derive it. Here one series skips a reporting period:

Example

canvas · responsive

Usage

React

import { LineChart } from "@michi-vz/react";

export default () => <LineChart {...props} />; // props = the chart options

Vue

<script setup>
import { LineChart } from "@michi-vz/vue";
</script>

<template>
  <LineChart :options="props" />
</template>

Svelte

<script>
  import { lineChart } from "@michi-vz/svelte";
</script>

<div use:lineChart={props}></div>

Angular

// main.ts - register the elements once
import "@michi-vz/angular";
import { applyLineChartProps } from "@michi-vz/angular";

// component (uses CUSTOM_ELEMENTS_SCHEMA)
// template: <michi-vz-line-chart #c></michi-vz-line-chart>
applyLineChartProps(this.c.nativeElement, props);

Web component

<script type="module" src="https://cdn.jsdelivr.net/npm/@michi-vz/wc"></script>

<michi-vz-line-chart id="c"></michi-vz-line-chart>
<script>
  Object.assign(document.getElementById("c"), props); // dataSet/series, title, …
</script>

Vanilla JS

import { mountLineChart } from "@michi-vz/core";

const chart = mountLineChart(el, props);
chart.update(next);
chart.getContext(); // renderer-agnostic, LLM-ready
chart.destroy();

API

Props are typed as LineChartProps in @michi-vz/core. Shared across all charts: width, height, margin, colors / colorsMapping, renderer ("svg" | "canvas"), highlightItems, disabledItems, and the on* callbacks. onChartDataProcessed / getContext() return the renderer-agnostic ChartContext.
