Line Graph Maker
Plot a line graph from label and value lines and export it as SVG or PNG. Your work stays on this device whenever possible.
How to use Line Graph Maker
- Type a title and an optional value axis label.
- Enter your points as "label, value" lines in order, such as days or months.
- Pick the line color and decide whether values are shown on each point.
- Download the line graph as SVG or PNG.
Worked example
Enter Mon, 12 / Tue, 18 / Wed, 15 / Thu, 24 / Fri, 30 / Sat, 27 / Sun, 21 with the title Visitors this week. The line rises to its peak on Friday at 30, each point labelled, and the SVG downloads at 640 x 400.
When to use this tool
- Tracking weekly visitors, steps or weight over time.
- Showing a trend in a science or business assignment.
Important limitations
Draws a single line with points evenly spaced in the order typed, not by real time gaps.
Frequently asked questions
What order are the points drawn in?
Exactly the order you type them. The tool does not sort labels, so list dates or months in time order.
Can I plot more than one line?
This version draws a single line. Make one chart per series if you need to compare several.
Does it support dates on the x-axis?
Labels are treated as text, so any date format works, but points are spaced evenly rather than by the real time between them.
Can values be decimals or negative?
Yes. Decimals are shown as typed (up to two places) and negative values extend below the zero line.
Is the data private?
Yes. The graph is drawn in your browser and nothing is uploaded.
