how to customize 2D plot lines with shapes?
显示 更早的评论
Hello, i'm writing a document that will be printed with only black printer cratrage, my plots are consisted of several lines each with its own color, how can i change them from simple blue line to line with square and line with triangle etc.. ?
CEM43=20:1:50;
R=0.5;
t=0.1/60;
T=43+log(t./CEM43)./log(R);
semilogy(CEM43,T)
hold on
t=0.2/60;
T=43+log(t./CEM43)./log(R);
semilogy(CEM43,T)
t=0.3/60;
T=43+log(t./CEM43)./log(R);
semilogy(CEM43,T)
legend('t_i=0.1 [sec]','t_i=0.2 [sec]','t_i=0.3 [sec]','location','southeast')

The easiest way is to add it when you plot
plot(x,y,'style')
where 'style' is a combination of color, marker and linestyle, in that order. For example
plot(x,y,'rs--')
gives you a dashed red line with square markers. A list of marker and linetypes can be found in the doc . By default you get a marker on each data-point. You can however reduce the frequency of markers by specifying a vector with 'MarkerIndices' if you have a new version of MATLAB.
It is proper to always output a handle when you plot something.
h = plot(x,y)
By doing so, you can easily change the lineproperties of that plot after plotting, for example:
set(h,'linestyle','--','color','r','marker','s')
You can set the property for multiple line objects on a single line, by passing all your handles into the set function.
If you fancy some specific set of marker/linestyles, then you could also learn about the 'LineStyleOrder' argument of the axes. You can basically configure the axes to use a certain set of marker/linestyles, just like the default is to use a certain set of colors.

You can use line specifications with semilogy same as plot. See the details in link below:
Try this code:
semilogy(CEM43,T,'b^') % For blue&triangle
semilogy(CEM43,T,'Color','b','Marker','square') % for blue&square
semilogy(CEM43,T, 'Color', 'b', 'Marker', 'diamond') % for blue&diamond
