How to Use

  1. 1

    Paste your columns

    Copy label + two value columns straight from Excel or Google Sheets — the first column becomes the bars, the second the line, named from the header row.

  2. 2

    Drag either series

    Drag a bar top or a line point and it moves against its own axis. Tap one for an exact value, color, or remove.

  3. 3

    Touch the chart to edit it

    Click the title, axis names, x labels, series names in the legend, or the value labels and type.

  4. 4

    Pick a layout and look

    Dual axis for different units, shared scale, or indexed-to-100 for comparing movement — per-series units and colors, five themes, three sizes.

  5. 5

    Download PNG

    Export a PNG that matches the preview 1:1 — free with no watermark.

Frequently Asked Questions

What is a combo chart?

A combo (combination) chart overlays two different chart types — typically bars and a line — on the same axes. This lets you compare two related metrics with different scales in one visual.

When should I use a combo chart?

Use combo charts when you have two related metrics with different units or scales — like revenue (dollars) and growth rate (percentage), or sales volume and average price.

Does it support dual Y-axes?

Yes. Use Dual axis when bars and line values have different units or scales. You can also switch to Shared scale or Indexed trend when those views make the comparison clearer.

Can I customize labels and values?

Yes. The combo chart studio includes editable chart title, subtitle, axis labels, metric names, value prefixes, value suffixes, colors, and category values.
