Free Line Graph Maker
Paste a table or upload CSV data, compare multiple series, customize the axes, and export a clean line graph.
What Is a Line Graph?
A line graph connects values across an ordered sequence, making changes, trends, peaks, and declines easy to compare. It is especially useful for time series such as monthly revenue, daily temperatures, website traffic, or project metrics.
Line Graph Maker Features
Paste a complete table
Copy rows directly from Excel or Google Sheets, or paste comma-separated data. The first column supplies the X-axis labels and each additional numeric column becomes a separate line.
Upload CSV data
Upload a CSV or TXT file and continue editing the imported table in the data panel before exporting your chart.
Compare multiple series
Plot several related measurements on one shared axis, assign a color to each series, and use the legend to keep comparisons readable.
Control the presentation
Add a chart title and axis labels, set an explicit Y-axis range, choose straight or smoothed lines, and toggle gridlines, points, and the legend.
Export without a watermark
Download the completed line graph as PNG, PDF, or editable SVG. All processing happens in your browser and no account is required.
How to Make a Line Graph
- Paste a table or upload a CSV file. Include labels in the first column and one or more numeric series.
- Set the chart title, axis labels, range, colors, gridlines, points, and legend.
- Download the finished graph as PNG, PDF, or SVG.
Line Graph vs Line Chart
Line graph and line chart usually describe the same visualization: ordered values connected by lines. Use one when the order matters, particularly for change over time. Use a scatter plot instead when the goal is to study correlation between two independent numeric variables.
How to Make a Line Graph in Excel
Put labels in the first column and each series in a separate column, select the complete table, then choose Insert, Line Chart. For a faster browser workflow, paste the same selected table into the tool above.
How to Make a Line Graph in Google Sheets
Select a table with headers, choose Insert, Chart, and set the chart type to Line chart. You can also copy those cells and paste them above to customize and export the result without changing the spreadsheet.
Multiple Lines: Double, Triple, and Multi-Line Graphs
Add another numeric column for every line you need. A two-line graph compares two measurements, while three or more lines work well when every series shares the same unit and scale. Avoid combining unrelated units on one axis.
When to Use a Line Graph
Choose a line graph for ordered or time-based measurements. Choose a bar chart for independent category totals, a histogram for a numeric distribution, or a scatter plot for relationships between paired numeric variables.
Frequently Asked Questions
How can I create my own line graph?
Paste a labeled table, customize the graph, and download it. No installation or account is required.
Can I upload data to create a line graph?
Yes. Upload a CSV or TXT file, or paste data copied from Excel or Google Sheets.
Can I make a line graph with multiple lines for free?
Yes. Put each series in its own numeric column and the tool will draw the lines together with a shared legend.
Can I edit the data after uploading a CSV?
Yes. Uploaded content is placed in the data editor, where you can correct labels or values before exporting.
Can I download the graph as SVG?
Yes. The graph is rendered as vector SVG and can be downloaded as SVG, PNG, or PDF.
