How to Draw Lines on a Coordinate Plane

Draw a segment by connecting two points that are already on the graph, or click two grid intersections and let Graph Editor create any missing endpoint points automatically.

Need help plotting points first? See the plotting points tutorial.

What you'll create

A coordinate graph with styled line segments joining existing and newly placed points.
1

Start with two existing points

This example begins with a prepared coordinate plane and two plotted points: A at (-3, 2) and B at (2, -2). There is no need to change the axes or grid before continuing.

Switch to Line mode

Choose Line from the Select / Point / Line control. Line mode waits for two endpoints, then creates a segment between them.

Choose two endpoints

Click one grid position, then another. Each click snaps to the configured X and Y grid step.

Either method works

Choose an existing point to reuse it, or choose an empty grid intersection to create a new endpoint point.
3

Connect the existing points

Click point A, then point B. Graph Editor creates the segment and reuses both points instead of placing duplicates.

  • Click the first existing point.
  • Click the second existing point.
  • The existing endpoints are reused.
  • A → B and B → A are the same segment, so selecting the points in reverse does not create a duplicate.

Choose a new first endpoint

You can also draw a line without plotting its endpoint points beforehand. Keep Line mode active and click an empty grid intersection to set the first endpoint.

The pending endpoint shows where the segment will begin. The selected coordinate snaps to the configured X and Y grid step, just like a point placed in Point mode.

Complete the direct line

Click a second empty grid intersection. Graph Editor completes the segment and automatically creates endpoint points at both chosen positions.

Select and style a line

Return to Select mode and click a segment to open its inspector. You can also return here later whenever an existing line needs editing.

Line styling controls

  • Choose a line color.
  • Use a solid, dashed, or dotted style.
  • Adjust the stroke width.

Every styling change updates the graph immediately.

Export the finished graph

Open Download when the graph is ready, choose the format that fits your next task, and save the result.

Next steps

You have connected existing points, drawn directly between grid intersections, created missing endpoint points automatically, and styled selected segments.
