This is only valid in combination with the@ or -@ specifiers.If c is one of "r", "g", "b", "m", "c", or "w", it is interpreted as the plotcolor (red, green, blue, magenta, cyan, or white).‘";title;"’Here "title" is the label for the key.‘+’‘*’‘o’‘x’Used in combination with the points or linespoints styles, set the pointstyle.The color line styles have the following meanings on terminals that support color.Number Gnuplot colors (lines)points style1 red *2 green +3 blue o4 magenta x5 cyan house6 brown there existsThe fmt argument can also be used to assign key titles. To do so, include the desiredtitle between semi-colons after the formatting sequence described above, e.g. "+3;KeyTitle;" Note that the last semi-colon is required and will generate an error if it is leftout.Here are some plot examples:plot (x, y, "@12", x, y2, x, y3, "4", x, y4, "+")This command will plot y with points of type 2 (displayed as ‘+’) and color 1 (red),y2 with lines, y3 with lines of color 4 (magenta) and y4 with points displayed as ‘+’.plot (b, "*")This command will plot the data in the variable b will be plotted with points displayedas ‘*’.t = 0:0.1:6.3;plot (t, cos(t), "-;cos(t);", t, sin(t), "+3;sin(t);");This will plot the cosine and sine functions and label them accordingly in the key.
