%Order of line styles and markers used in a plot.
%This property specifies which line styles and markers to use and in what order
%when creating multiple-line plots. For example,set(gca,'LineStyleOrder', '-*|:|o')sets LineStyleOrder to solid line with asterisk
%marker, dotted line, and hollow circle marker. The default is (-), which specifies
%a solid line for all data plotted. Alternatively, you can create a cell array
%of character strings to define the line styles:set(gca,'LineStyleOrder',{'-*',':','o'})MATLAB supports four line styles, which you can specify any number of
%times in any order. MATLAB cycles through the line styles only after using
%all colors defined by the ColorOrder property. For example,
%the first eight lines plotted use the different colors defined by ColorOrder with
%the first line style. MATLAB then cycles through the colors again, using the
%second line style specified, and so on.You can also specify line style and color directly with the plot and plot3 functions
%or by altering the properties of theline or
%lineseries objects after creating the graph. High-Level Functions and LineStyleOrderNote that, if the axes NextPlot property is set
%to replace (the default), high-level functions like plot reset
%the LineStyleOrder property before determining the line
%style to use. If you want MATLAB to use a LineStyleOrder that
%is different from the default, set NextPlot to replacechildren. Specifying a Default LineStyleOrderYou can also specify your own default LineStyleOrder.
%For example, this statementset(0,'DefaultAxesLineStyleOrder',{'-*',':','o'})
