dashline

Plots dashed and dotted lines with user-defined linestyles, and with accurate dash lengths.

Dashline is an m-file which was written to give accurate control over dashed and dotted lines, for producing publication quality graphics. The inbuilt line-styles in Matlab are limited and often give poor results. Dashline gives the user freedom to produce any combination of dashes and markers they wish. It is based on a two dash repeat pattern, with the user giving the lengths of the two dashes and the two gaps (in mm), or specifying markers to be used in place of the dashes.

dashline( Xdata, Ydata, Dash1, Gap1, Dash2, Gap2, ...) plots the data in xdata and ydata with a line that has dashes of length Dash1 and Dash2, separated by gaps of length Gap1 and Gap2 (all in mm). Dash1 and Dash2 may be plotsymbol strings, such as '+'. Additional property/value pairs may be included and will set properties of the plotted lines.

An example:

>clf
>dashline([1:10],rand(1,10),'.r',2,'.g',2)

% produces a dashed line with red and green dots
% separated by 2mm gaps

>hold on;
>dashline([1:10],rand1,10),4,2,'o',2,'markerfacecolor','y','color','k')

% produces a line with black dashes and yellow centered
% circles
