| Spacing Calculation | |
| =================== | |
| Flotr | |
| calculate data | |
| calculate margins | |
| Chart | |
| calculate Data Ranges - Explicit or auto data minimum, maximums | |
| calculate Data Range Extensions - By chart type, extend data range with needs of chart type (ie. stacked bars, stacked lines) | |
| add Chart Padding - By chart type | |
| Text | |
| use explicit margins | |
| calculate label margins | |
| calculate title margins | |
