How to Use
- 1
Paste or type your data
Paste a range from Excel or Google Sheets with the labels in the first column, or type lines like "Jan 42". Each extra column becomes its own line, named from the header row.
- 2
Drag points into place
Pull any point up or down to set its value, or click a value and type the exact number.
- 3
Label everything
Click the title, the axis names, the labels along the bottom, or a line's name and type over it. Add up to six lines and 24 points.
- 4
Style the lines
Fill the area under a line, make a line dashed, smooth the curves, and turn point markers, values, and grid lines on or off.
- 5
Pick a look and download
Choose one of five themes (including a hand-drawn Sketchbook look for school work) and three canvas sizes, then download a PNG that matches the preview exactly.

Frequently Asked Questions
How do I make a double line graph?
Paste two value columns, or start from the Comparison sample, and you get two lines on the same axes with a legend. Make one of them dashed so the graph still reads clearly when printed in black and white.
Can I make a line graph from Google Sheets?
Yes. Select the cells in Sheets (a label column plus up to six value columns), copy them, and paste them into the paste box. The header row becomes the line names.
Is this good for science class?
Yes. It plots change over time, like temperature, plant growth, or distance, with clear points and labelled axes, and it needs no account or install. Download the PNG for a lab report or a poster.
Should I use a line graph or a scatter plot?
Use a line graph when your points follow an order, usually time, so connecting them shows the trend. Use a scatter plot when you are checking whether two measurements move together; the scatter chart maker can add a trend line for that.
Is this line graph maker free?
Yes. Make and download line graphs as PNG files for free, with no signup and no watermark. HD sizes, SVG, and MP4 exports are Pro.
