Line Graph Maker
Plot a trend over time with a line graph, such as website visits by week, temperatures by month or prices by year. Points are joined in the order you enter them. Add more columns to compare several series, and use markers and value labels to make every change easy to follow.

How to use Line Graph Maker
- Enter time periods as labels and one column of values per series.
- Add a title and axis titles such as Month and Revenue.
- Choose straight, smooth or step lines in the chart gallery.
- Download the line graph as PNG, JPG, SVG, PDF, Excel or PowerPoint.
Features
- Multiple series, each with its own colour and legend entry.
- The value axis includes zero when your values are near it and fits the data when they are not, so small changes on large values stay visible.
- Smooth lines never overshoot your data points.
- Excel and PowerPoint exports contain a native, editable line chart.
Supported formats and limitations
Input: typed data, pasted spreadsheet cells, CSV/TSV, or Excel .xlsx/.xls/.ods (first sheet). Output: PNG and JPG (up to 3× resolution), SVG, PDF, Excel .xlsx and PowerPoint .pptx.
- Step lines are exported to Excel and PowerPoint as a picture, because Office has no step chart.
Frequently asked questions
When should I use a line graph instead of a bar graph?
Use a line graph when the labels follow a natural order such as dates, and you want to show how a value rises or falls between them.
Does the order of my rows matter?
Yes. Points are connected from the first row to the last, so enter time periods in chronological order.
Can I plot several lines?
Yes. Each extra numeric column becomes another line, up to 23 series.
