Free online line chart maker. Input your data to instantly generate custom line graphs. Customize titles, colors, and download as PNG to visualize trends.
Supports comma, semicolon, or tab delimiters. The first cell of the first row is the X-axis name, and the rest are series names.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Paste a small delimited table with a header row. The first column supplies the horizontal labels, such as months or dates; each remaining column becomes a separate numeric series. The header names appear as series labels in the legend. The preview redraws as the table and display settings change.
A line chart connects values across an ordered set of labels, making it easier to see how series move across those positions. The generator renders the values you provide; it does not detect a trend, fit a statistical model, forecast future values, or judge whether a pattern is meaningful.
Include at least two columns and a header plus one data row. Use tabs, commas, semicolons, or their full-width forms to separate cells. The first header is the horizontal-axis key and the following headers name the lines. Numeric cells are plotted as values. A blank or nonnumeric cell is treated as zero, so clean those cells before charting if zero would misrepresent missing data.
Quoted CSV fields are not parsed as a full CSV standard: commas inside quoted text are still treated as separators. Keep labels simple and avoid delimiters inside a cell. For example, use Month,Revenue,Costs followed by rows such as Jan,120,80.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Put the category labels in the first column and one or more numeric series in the columns to its right. Use the first row for headers.
Add a title and optional horizontal- and vertical-axis labels so the image remains understandable when shared.
Choose a smooth, straight, or step-shaped line, set the stroke width, and toggle point markers, grid lines, and legend. You can set a color for each series.
Save the rendered chart as PNG for a common image workflow or SVG for a scalable vector graphic.
Use cases
See how the tool fits into real work and everyday tasks.
Paste months in the first column and metrics such as visits or sales in separate series to create a report graphic.
Arrange the observation labels in order and plot numeric measurements to make a classroom data table easier to read.
Compare several named series on one chart, then export an image for a slide or note. Confirm axis units before sharing.
Q&A
Find concise answers to common questions and confusing cases.
This interface accepts pasted or typed delimited text in its data area; it does not expose a file-upload control.
Series cells are converted to numbers, and blank or nonnumeric entries are rendered as zero. Replace them with valid numbers or revise the table before exporting.
No. It draws the supplied values and does not perform statistical analysis or trend testing.
The available export buttons are PNG and SVG.
Notes
Review scope, result limitations, and important precautions before use.
The chart faithfully reflects the table parsing rules, including the conversion of invalid numeric cells to zero. Review the series count, labels, units, and missing values before using the image in a report. The plotted line is a visual aid and does not establish causation, statistical significance, or a forecast.
