Number line
Set the range and the step. Click to drop a marker, drag from one point to another to draw a jump. Works for negatives, decimals, thousands.
Click a tick to mark it. Drag between two ticks to draw a jump.
How to use it
- Type the start, end and step. For negatives put −10 to 10. For decimals put 0 to 1 with step 0.1. "Label every" thins out the numbers when there are a lot of ticks.
- Click a tick to mark it; click again to remove. Press and drag from one tick to another to draw a jump with its size on it. The readout keeps a running total.
- Tick "Hide numbers" for a blank line; marked ticks still show their value, so you can ask "what goes here?"
