The CanvasRenderingContext2D method lineTo(), part of the Canvas 2D API, adds a straight line to the current sub-path by connecting the sub-path's last point to the specified (x, y) coordinates.

Like other methods that modify the current path, this method does not directly render anything. To draw the path onto a canvas, you can use the fill() or stroke() methods.


ctx.lineTo(x, y);


The x-axis coordinate of the line's end point.
The y-axis coordinate of the line's end point.

Return value



Drawing a straight line

This example draws a straight line using the lineTo() method.


<canvas id="canvas"></canvas>


The line begins at (30, 50) and ends at (150, 100).

const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

ctx.beginPath();       // Start a new path
ctx.moveTo(30, 50);    // Move the pen to (30, 50)
ctx.lineTo(150, 100);  // Draw a line to (150, 100)
ctx.stroke();          // Render the path


Drawing connected lines

Each call of lineTo() (and similar methods) automatically adds to the current sub-path, which means that all the lines will all be stroked or filled together. This example draws a letter 'M' with a single contiguous line.


<canvas id="canvas"></canvas>


const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

ctx.moveTo(90, 130);
ctx.lineTo(95, 25);
ctx.lineTo(150, 80);
ctx.lineTo(205, 25);
ctx.lineTo(210, 130);
ctx.lineWidth = 15;
