If the lines or text on a graph appear slightly fuzzy, it is likely caused by antialiasing. Antialiasing is a technique used to add greater realism to a digital image by smoothing jagged edges on curved lines and diagonals. When this is not desirable, it can be turned off in the Grapher program.
To turn off antialiasing:
- Click File | Options.
- On the left side of the Options dialog, click Display.
- On the right side of the dialog, uncheck the box next to Antialias lines to remove the smoothing from lines in the graph.
- Uncheck the box next to Antialias text to remove the smoothing from text and labels in the graph.
- Click OK and the lines and/or text will be drawn without the antialias smoothing.
If you ever wish to turn antialiasing back on, follow the steps above, but check the boxes next Antialias lines and Antialias text.
