| 9 | // Example file for odometer graph. This examples extends odoex04 |
---|
| 10 | // by 1) changing color of odometer canvas 2) Adding a second indicator |
---|
| 11 | // needle 3) making the tick marks thicker 4) and finally adding a short |
---|
| 12 | // scale text in the middle of the odometer. |
