= MATLAB Plot = The '''`plot`''' function creates a 2D graphic of a curve. <> ---- == Usage == {{{ x = 0:pi/100:2*pi; y = sin(x); figure; plot(x,y); }}} See also [[MATLAB/FiguresAndRelatedCommands|figures and related commands]]. ---- == Line Specifications == Basic line specifications can be made with a single string argument. More detailed specifications require named properties to be set individually. === Shorthand === Lines and markers are styled by passing a symbolic string as an argument. This string is composed of component specifications. Line components are styled with the following specifications: ||'''Name''' ||'''Specification'''|| ||Solid ||`-` || ||Dashed ||`--`|| ||Dotted ||`:` || ||Dash-dotted||`-.`|| Marker components are styled with the following specifications: ||'''Name''' ||'''Specification'''|| ||Circle ||`o` || ||Plus sign ||`+` || ||Asterisk ||`*` || ||Point ||`.` || ||Cross ||`x` || ||Horizontal line ||`_` || ||Vertical line ||`|` || ||Square ||`s` || ||Diamond ||`d` || ||Upward-pointing triangle ||`^` || ||Downward-pointing triangle||`v` || ||Right-pointing triangle ||`>` || ||Left-pointing triangle ||`<` || ||Pentagram ||`pentagram`|| ||Hexagram ||`hexagram` || Note that "-." means a dash-dotted line, whereas ".-" means point markers and a line. This also demonstrates that line specifications do not need to follow an order. Lastly, there are color components. As an example, red is specified by `r`. This is not generally useful though, as any plot with multiple lines should use different colors for each. Colors are automatically assigned in a reasonable manner. ||'''Name'''||'''Specification''||'''Equivalent RGB Triplet'''||'''Equivalent hexadecimal code'''|| ||Red ||`r` ||`[1 0 0]` ||`"#FF0000"`|| ||Green ||`g` ||`[0 1 0]` ||`"#00FF00"`|| ||Blue ||`b` ||`[0 0 1]` ||`"#0000FF"`|| ||Cyan ||`c` ||`[0 1 1]` ||`"#00FFFF"`|| ||Magenta ||`m` ||`[1 0 1]` ||`"#FF00FF"`|| ||Yellow ||`y` ||`[1 1 0]` ||`"#FFFF00"`|| ||Black ||`k` ||`[0 0 0]` ||`"#000000"`|| ||White ||`w` ||`[1 1 1]` ||`"#FFFFFF"`|| ||None ||`none` || || || The equivalences shown above are not useful for this shorthand, but are good to note for the below. === Properties === Try either of the following: {{{ plot(x,y,LineWidth=3) plot(x,y,"LineWidth",3) }}} Note that the latter is considered the legacy, backwards-compatible method. ||'''Name''' ||'''Meaning''' ||'''Domain''' ||'''Example''' ||'''Default'''|| ||`Color` ||Line color || ||`"r"`, `[1 0 0]`|| || ||`LineStyle` ||Line style || ||`"--"` ||`"-"` || ||`LineWidth` ||Line width ||Positive numbers (pts)|| ||0.5 || ||`Marker` ||Marker style || ||`"o"` ||`"none"` || ||`MarkerIndices` ||Markers to display ||Positive numbers ||`[1 5 10]` ||`1:end` || ||`MarkerEdgeColor` ||Marker outline color || ||`"r"`, `[1 0 0]`||`"auto"` || ||`MarkerFaceColor` ||Marker fill color || ||`"r"`, `[1 0 0]`||`"none"` || ||`MarkerSize` ||Marker size ||positive numbers (pts)|| ||6 || ||`DatetimeTickFormat`||Format string for datetimes|| ||`"yyyy-MM-dd"` || || ||`DurationTickFormat`||Format string for durations|| ||`"dd:hh:mm:ss"` || || ---- CategoryRicottone
