The rule
A 100% stacked bar gives every bar the same height. Each segment shows a share of its own bar. A share is a part of a whole, as a percent.
| Crop | Season 1 | Season 2 |
|---|---|---|
| Paddy | 40 of 100 = 40% | 80 of 200 = 40% |
| Ragi | 25 of 100 = 25% | 50 of 200 = 25% |
| Pulses | 35 of 100 = 35% | 70 of 200 = 35% |
The two bars look identical. The shares are the same, but the totals are not.
A 100% bar shows shares only. Read a count only when the total is written beside it.
With the total, a share becomes a count. 25% of 200 is 25 ÷ 100 × 200 = 50. That is 50 quintals of ragi.
A pie chart marked only in percentages also shows shares only.
