Height Chart Comparison — Two Groups, One Scale
Put Group A next to Group B on a single shared axis: a family versus a basketball five, your class versus theirs. This height chart comparison draws both line-ups together and reports each group’s average so the verdict is numerical as well as visual.
- Two groups
- Shared axis
- Group averages
Outlines are illustrative silhouettes; every plotted value is a real measured figure on one shared true-to-scale axis.
When one group is not enough
Single-group height charts answer “how do we spread out?” — but the interesting questions are usually comparative. Does the volleyball first six tower over the basketball second five? Is this year’s class taller than last year’s? A height chart comparison answers by drawing both groups on one canvas, tagged A and B, sharing one ruler so no one can cheat with a private scale.
The page opens with a classic matchup: a family (child, mother, father) against a basketball line-up (point guard, forward, center). Both groups share the same pixels-per-centimeter, and the summary panel beneath the height chart comparison reports each group’s average height — the number that settles “which group is taller?” without a debate about outliers.
Edit every member, add up to a dozen per group, recolor and rename freely. When both line-ups are yours, the height chart comparison maker stops being a demo and becomes your argument, exported as a PNG nobody can dispute — and the same maker doubles as a growth tracker year over year.
How to run a two-group height chart comparison
Fill column A, fill column B, read the averages — the whole height chart comparison workflow.
1Edit Group A
Start from the sample family or clear it by resetting; add members with one tap and type real heights in any unit you like.
2Edit Group B
Same for the second group. Members are tagged A and B directly on the canvas so the height chart comparison never confuses the line-ups.
3Read and export
The summary shows each group’s average; the canvas shows every individual. Export the complete height chart comparison or share a link to the exact scene.
Two panels, one honest scale
Shared ruler and baseline
Both groups stand on the same ground line against the same ruler — the structural guarantee that a height chart comparison here means something.
Averages in the summary
Because “which group is taller?” is an averages question, the summary panel computes and displays each group’s mean height alongside the visual.
Group tags on canvas
Every silhouette carries its A or B tag, so even colorblind readers can follow which line-up is which in the exported height chart comparison image.
Height chart comparison example: the default match-up
The opening scene’s two groups and their numbers — a family versus a basketball line-up, averages included.
| Group A — Family | Height | Group B — Basketball | Height |
|---|---|---|---|
| Child | 120 cm | Point guard | 188 cm |
| Mother | 165 cm | Forward | 203 cm |
| Father | 180 cm | Center | 211 cm |
| Average | 155.0 cm | Average | 200.7 cm |
Group averages are computed live from your edited members, so the height chart comparison summary always matches the canvas exactly.
Comparing groups fairly
A fair height chart comparison needs comparable groups: similar headcounts, or at least averages that account for size. Three tall people versus ten of mixed heights can flip the visual while the averages tell the true story — which is why this page insists on printing both. Keep each group under about eight members and the labels stay legible in exports.
Interpret the gap between averages like any height difference: two or three centimeters between big groups is noise; ten centimeters is a real structural difference (think volleyball first team vs the whole school). When the two groups are the same people at different times — a team in September versus April — the height chart comparison quietly becomes a growth tracker.
height chart comparison — FAQ
How many members can each group hold?
Up to twelve per group on the height chart comparison canvas; six to eight per side keeps exported images crisp and labels readable.
Are the two groups on the same scale?
Always — one ruler, one ground line, one pixels-per-centimeter for both. That shared axis is what separates a real height chart comparison from two unrelated charts glued together.
How are group averages calculated?
As the simple mean of each group’s member heights, recomputed on every edit and displayed beneath the height chart comparison in your chosen unit.
Can I use it to track growth over time?
Yes — put this term’s heights in Group A and last term’s in Group B. The height chart comparison then shows the shift member by member and in the averages.
Can I export both groups in one image?
Yes — PNG and SVG exports capture the full canvas with both line-ups, group tags and the shared ruler in a single frame.
