A more convenient colormapping
显示 更早的评论
The figure above is the change in transmission intensity over distance. But the colormapping scheme does not encapture the full picture. There is very gradual change around 0 (in the colorbar) that is absent from this picture.
I have edited the colormap through trial and error to get the foloowing picture:
It does capture the broadband phenomena around 800nm and 875nm. But such an image is not suitable for journal publication. How can I make it more sophisticated? TIA
The code and files are given below:
clc; clear all;
load zpos;
A=T';
l=l*1e9;z=z*1e9;
figure
p=pcolor(l,z,A*1e15);
colormap jet(500); % 500 levels of granularity
shading interp; % interpolate colors across lines and faces
xlim([750 900]);
ylim([-620 100]);
xlabel('wavelength (nm)') ;%ylabel('z (nm)');
xticks([750 775 800 825 850 875 900]);
yticks([-526 -326 -126 74]);
yticklabels({'z=200','z=0','z=-200','z=-400'})
% set(gca,'Units','normalized');
% set(gca,'TickLength',[0.5,0.5]);
%colorbar setting
c = colorbar;
%labels the colorbar vertically as desired
set(get(c,'label'),'string','Emission (a.u.)');
c.TickLength=.023;
c.Units='normalized';
c.FontSize=28;
%font properties
FS='Fontsize';
fs=20;
FN='Fontname';
fn='Times New Roman';
set(findall(gcf,'type','axes'),FS,fs,FN,fn);
set(findall(gcf,'type','text'),FS,fs,FN,fn);

You could replace pcolor() with contourf(). The plot below uses 12 levels of contours. You can play around with the number of levels until you get the desired appearance.
contourf(l,z,A*1e15,12)

You can also customize the border line width (set it to 0 for no line) and you can optionally set contour labels, too.
