Stroke Draw Chart

Overview

Establish quiet grid lines, draw the illustrative trend in time order, then introduce the endpoint annotation as the line finishes arriving.

Build

1. 01

   Use a restrained grid to establish the chart scale.

2. 02

   Normalize the trend path with pathLength=1.

3. 03

   Animate stroke-dashoffset from 1 to 0 with a measured ease.

4. 04

   Draw the trend from 0.42 to 2.76 seconds; introduce the endpoint after arrival. Hold the complete chart, then fade the annotation before clearing the line for the loop.

pathLength=1; stroke-dasharray: 1;
trend: 0.42–2.76s; annotation: 2.76–3.3s;
annotation exit: 4.68–5.28s; line exit: 4.92–5.64s
