Three chart types that add a third axis: 3D scatter, 3D bar and 3D surface. Read on for when the extra dimension earns its place, and when a 2D scatter plot or heatmap will actually show your data more clearly.
3D chart templates plot three numeric variables at once (x, y and z) instead of the two a flat chart is limited to. On PlotSet that means three chart types: 3D scatter for a cloud of individual points in space, 3D surface for a continuous value that changes smoothly across a grid, and 3D bar for a small comparison across two categorical axes. All three share the same trade-off. You gain a dimension, but you lose the thing that makes 2D charts easy to read at a glance: a value you can measure with your eye against a single, unambiguous axis.
That trade-off is why 3D charts have a bad reputation, and mostly a deserved one. Perspective makes far bars look shorter than near ones of the same height. Points behind other points are simply gone unless someone rotates the view, which a static export or an embedded image can't do for the reader. A 3D bar chart with more than six or seven bars usually turns into a wall of overlapping boxes nobody can rank by eye. None of this is a PlotSet limitation. It's geometry: any tool rendering true 3D on a flat screen runs into the same occlusion and distortion.
So use 3D when the third axis is doing real work: terrain elevation, a temperature or pressure surface across two spatial dimensions, molecular structures, lidar or point-cloud data. Those are cases where x, y and z are all genuinely continuous and spatial meaning is the point. For everything else, a 2D chart usually communicates the same information more accurately. A scatter plot with the third variable mapped to point color or size reads faster than a 3D scatter rotated to a guessed angle, and a heatmap crossing two categorical axes against one number is easier to read accurately than a 3D bar chart in almost every case.
Use 3D surface when your value depends continuously on two spatial dimensions at once, like elevation across a landscape or temperature across a grid of coordinates. If z only depends on one of the two axes, you don't need the surface. A line or heatmap will show the same relationship without the perspective distortion.
3D scatter fits data where x, y and z are real coordinates, not proxies for something else: geographic points with altitude, molecular structures, lidar scans. The position in space is the actual fact being shown, which is exactly the case 3D was built for.
3D bar can work for a small comparison, two or three groups across two or three categories, as long as you pick a camera angle where no bar hides behind another. Past six or seven bars, occlusion usually wins and the chart stops being readable.
If your third value is there to add context rather than to plot real spatial position, don't reach for 3D at all. A 2D scatter plot with color or bubble size for that third variable, or a heatmap for two categorical axes against one number, reads faster and doesn't depend on rotation to avoid hiding data.
From a spreadsheet to a published chart, step by step.
If you're tempted by 3D because it looks impressive, check first: do you have three genuinely independent numeric variables, or two variables and a third you could encode as color or size instead? Most spreadsheets people bring to a chart tool turn out to be the second case.
Build a quick 2D scatter plot with the third variable mapped to color or bubble size, or a heatmap if two of your variables are categories. If that version already tells the story clearly, stop there. It's also easier for readers to screenshot, print and understand at a glance.
Use 3D scatter for individual points with real x, y, z coordinates, 3D surface for a value that varies continuously across a grid, and 3D bar only for a small number of categories on each axis. Matching the shape to your data is what keeps a 3D chart readable instead of just busy.
Import your spreadsheet with the x, y and z columns clearly labeled, then rotate the view before exporting until your most important points aren't hidden behind others. A static export can't be rotated by the reader the way an interactive chart can, so that one angle is doing all the communication work.

Open the editor3D charts earn their place when your data has three genuinely continuous, related variables: a surface like elevation or temperature across two spatial dimensions, or real x, y, z coordinates like a molecular structure or lidar scan. In those cases the third axis carries real spatial meaning, not just decoration. For most business data, like sales by region and month, a 2D chart with color or size encoding the third variable communicates faster.
