Instruction on plotting with Matlab and standard requirements

Plot several curves

Example 3 Curves

Prepare raw data files such as file1.dat, file2.dat, file3.dat

Suppose they are all two-column files (x,y)

Create m-file as the following

s1=load('file1.dat');
s2=load('file2.dat');
s3=load('file3.dat');

figure;plot(s1(:,1),s1(:,2),'b','linewidth',2);  ### b represents blue, it is recommended to use 2 for linewidth
hold on; plot(s2(:,1),s2(:,2),'r--','linewidth',2);  ## r represents red
hold on; plot(s3(:,1),s3(:,2),'k*','linewidth',2);   ## k represents black
legend('data1','data2','data3');                     ## label each curve correctly (fontsize 16)
xlabel('Distance','fontsize',20);     ## fontsize is recommended to use 20 or 24
ylabel('Probability','fontsize',20);  ## 

The legends and axis labels and numbers in all figures should be in large enough font so that they can still easily be seen when reduced in Size to the journal single column format used for their printed papers.

  Example pcolor

  Example surf

Please refer to MATLAB documentation on 'pcolor', 'surf', etc. The following is a quick start example about how to use them.

s=load(filename); ## suppose your file is a mXn matrix.
figure;pcolor(s);shading interp;
figure;surf(s);shading interp;
