The chart updates in real-time as you modify data. Customize colors, labels, and titles through the built-in controls.

Tips & Insights

Choose chart types strategically: use bar charts for comparing categories, line charts for trends over time, pie charts for showing parts of a whole (limit to 5-6 slices), and donut charts for a modern pie alternative. Keep datasets simple—overcrowding reduces clarity. Label axes clearly and include a title describing the data. For presentations, muted colors and clear typography improve readability on projectors.

Frequently Asked Questions

What types of charts can I create?

We support four types: bar charts, line charts, pie charts, and donut charts. Switch between them easily by clicking tabs.

How do I input data?

There are two methods: paste data in CSV format (label,value) into the text area, or manually add rows and input labels and values individually.

Can I customize chart colors?

Yes. Beautiful colors are applied automatically, but you can also customize each data item's color using the color picker.

Can I save the chart as an image?

Yes, you can download the graph as a PNG image by clicking on the "Download PNG" button. Click on the "Download PNG" button to download the currently displayed graph as a PNG image.

Is data sent to the server?

No. All processing happens in your browser. Your input data is never sent to a server. You can use it with confidence.

Can I edit my chart after I create it?

Yes, you can modify all aspects of your chart including data values, colors, title, and legend. Simply update the data in the input fields and the chart will refresh automatically in real-time. This allows you to experiment with different data presentations easily.

What's the maximum number of data points I can include?

There's no strict limit, but charts become crowded with too many data points (typically 50+). For clarity, keep bar and line charts under 20 categories. Pie charts are best with 5-8 segments, as more slices become difficult to distinguish.

Can I add a title and legend to my chart?

Yes, most chart makers include options to add a title at the top and configure the legend display. You can customize the title text and position the legend on different sides of the chart. Both elements help viewers understand your data clearly.

What image format can I save my chart as?

Charts can typically be saved as PNG or JPG image files, with PNG recommended for better quality. Some versions also support SVG format for scalable vector graphics. Choose PNG for most cases as it balances quality and file size.

Can I export my chart as SVG for editing in design tools?

Some chart makers support SVG export which allows you to edit the chart further in tools like Adobe Illustrator or Inkscape. SVG charts scale perfectly at any size without quality loss. Check if your chart tool offers SVG download option in the export menu.

How do I create a grouped or stacked bar chart?

To create grouped bars, input multiple data series with the same category names—the tool will display them side-by-side. For stacked bars, some tools have a chart type option specifically for stacking. Consult the tool's documentation for your specific variant's syntax.
