What is a 3D Bubble Chart?

A 3D bubble chart extends the standard bubble chart by adding a third positional axis. Each data point is a sphere whose position in space is determined by its X, Y, and Z values, while the size of the sphere encodes a fourth numeric dimension — typically a magnitude or weight. An oblique projection maps the three axes onto the 2D canvas: X is horizontal, Y is vertical, and Z goes diagonally into the depth of the chart.

How Do I Enter Data?

Each row is one data point. Fill in the six columns:

X — horizontal position (numeric)
Y — vertical position (numeric)
Z — depth position (numeric); higher Z values appear further back
Value — bubble size (numeric; negative values produce a same-size bubble as positive, shown as an outline only)
Group — optional; points with the same group name share a color and appear in the legend
Name — optional; a label displayed on or near each bubble

Click Example to pre-fill sample data, then Calculate Chart to render.

How Are Groups and Colors Used?

When you fill in the Group column, each unique group name gets its own color from the selected color palette. A legend is drawn on the right side (or top) of the chart listing each group. If the Group column is empty, all bubbles share the first color from the palette.

How Do I Customize the Axes?

Open the Appearance section to control axis titles, ranges, and tick intervals for all three axes independently. Use the Z Range fields to set a custom minimum, maximum, and tick interval for the depth axis. The Z axis is drawn as an oblique line at the bottom-left corner of the chart.
