Reading Rose Charts
A rose chart uses sector radius length to highlight value-size differences, making it more visually striking than a standard pie chart. Understanding the following style options makes your chart more expressive:
| Style Option | Effect | Tip |
|---|---|---|
| Radius Rose | Sector radius is proportional to value size | Use to emphasize value differences |
| Area Rose | Sector area is proportional to value size | Use to show share composition |
| Hollow Ring | Leaves the center empty to highlight share differences | Works best with fewer categories |
