Create scientific graphs from replicate data
This free online scientific graph maker turns pasted spreadsheet data into clear X-Y plots, scatter plots, bar charts, and grouped bar charts. It is designed for experimental datasets where each condition may have replicate measurements and where the mean, variation, individual points, and fitted trend all need to remain understandable.
Paste columns from Excel, Google Sheets, Prism, or a CSV file; choose the chart type; then adjust labels, colors, axes, error bars, and display options. X-Y graphs support linear or log axes and curve fitting. Finished figures can be downloaded as editable SVG files, high-resolution PNG images, or printed directly.
Choosing a graph for lab data
- X-Y plot: use for dose-response data, time courses, standard curves, and measurements with a continuous independent variable.
- Bar or column graph: use to compare a small number of discrete experimental groups.
- Grouped bars: use when each category contains multiple treatments, genotypes, time points, or other related series.
Error bars summarize variation but do not all mean the same thing. Select the measure that matches your analysis and state whether the figure shows standard deviation, standard error, or a confidence interval in the figure legend.
Scientific graph maker FAQ
Can I make a graph with error bars from replicate measurements?
Yes. Enter or paste replicate values for each X value or category. The graph can show the summary value with error bars and can also display the individual data points.
Can I paste data directly from Excel or Google Sheets?
Yes. Copy a rectangular range from a spreadsheet and use the import control. Review the detected columns before adding them to the graph.
Which export format should I use?
Use SVG when you want a scalable vector figure that can be edited later. Use PNG for slides, documents, and quick sharing. Always check the target journal or presentation requirements before submission.
