Whenever you create a plot in MATLAB, you need to identify the sources of information using more than just the lines. Creating a plot that uses differing line types and data point symbols makes the plot much easier for other people to use. The following table contains a listing of the line plot styles.
| Code | Line Color | Code | Marker Style | Code | Line Style |
|---|---|---|---|---|---|
| b | blue | . | point | - | Solid |
| g | green | o | circle | : | Dotted |
| r | red | x | x-mark | -. | dash dot |
| c | cyan | + | plus | -- | Dashed |
| m | magenta | * | star | (none) | no line |
| y | yellow | s | square | ||
| k | black | d | diamond | ||
| w | white | v | down triangle | ||
| ^ | up triangle | ||||
| left triangle | |||||
| > | right triangle | ||||
| p | 5-point star | ||||
| h | 6-point star |
Remember that you can also use these styles with other kinds of plots. For example, a scatter plot can use these styles to define each of the data points. When in doubt, try the styles to see whether they work with your particular plot.
