Create bar, line, pie, doughnut, and scatter charts from your data with SolveBar's Chart Builder. Paste CSV or type values directly, customize colors and labels, and export your chart as a PNG image — no account, no subscription, no watermark.
Choosing the right chart type
Bar charts compare discrete categories. Line charts show trends over time. Pie and doughnut charts show proportions of a whole (use only when parts add to 100% and you have fewer than 6 categories). Scatter charts show correlations between two continuous variables.
Data formatting for charts
Enter data as two columns: labels in the first column, values in the second. The first row should be column headers. Ensure numeric values are pure numbers without currency symbols or percentage signs.
Chart design best practices
Keep charts simple — every element should serve the story. Start axes at zero for bar charts. Use consistent colors across related charts. Add a clear title and axis labels. Sort bars by value rather than alphabetically for comparison charts.
Frequently Asked Questions
Can I add multiple data series to one chart?
Yes. For bar and line charts, add additional columns in your CSV — each becomes a separate series with its own color.
What resolution does the exported PNG have?
The exported image uses device pixel ratio for clarity, typically 2x resolution on modern screens, suitable for presentations and documents.
Can I use this to build charts for reports?
Yes. Create your chart, customize colors to match your brand, and export as PNG for embedding in Word, PowerPoint, or PDF documents.
