% IRFNOTES Notes on how to use irf routines
% Includes different examples that can be directly used
%
% IRFNOTES opens file with all the different examples
%
% enable code folding!!! (including cells and if/endif blocks)
% This allows to fast find your necessary examples and execute them.
%
edit irfnotes; return
%% Initialize figure
% fast way
h=irf_plot(5,'newfigure'); %#ok<UNRCH>
% h= irf_plot(number_of_subplots,'newfigure');
% example to set subplot position manually
h(1)=axes('position',[0.65 0.78 0.2 0.2]); % [x y dx dy]
% more detailed way
% most lines needed to define the size to have best agreement with eps file
set(0,'defaultLineLineWidth', 1.5);
fn=figure(61);
clf reset;
clear h;
set(fn,'color','white'); % white background for figures (default is grey)
set(gcf,'PaperUnits','centimeters')
xSize = 12; ySize = 24;
xLeft = (21-xSize)/2; yTop = (30-ySize)/2;
set(gcf,'PaperPosition',[xLeft yTop xSize ySize])
set(gcf,'Position',[10 10 xSize*50 ySize*50])
set(gcf,'paperpositionmode','auto') % to get the same printing as on screen
clear xLeft xSize sLeft ySize yTop
% additional good options
set(gcf,'defaultAxesFontSize',14);
set(gcf,'defaultTextFontSize',14);
set(gcf,'defaultAxesFontUnits','pixels');
set(gcf,'defaultTextFontUnits','pixels');
%% Print the figure as it looks on screen
set(gcf,'paperpositionmode','auto') % to get the same on paper as on screen
% to get bitmap file
print -dpng delme.png
% to get pdf file with no white margins:
% 1) print eps file from matlab
print -depsc2 -painters -loose delme.eps % -loose is necessary for MATLAB2014 and later
% 2) from terminal convert to eps file without white margins
% epstool routine can be installed, e.g. on mac >brew install epstool
% > epstool --copy --bbox delme.eps delme_crop.eps
% 3) convert eps file to pdf, result is in delme_crop.pdf
% > ps2pdf -dEPSFitPage -dEPSCrop -dAutoRotatePages=/None delme_crop.eps
%% Add information to figures
%
% text and legends
help irf_legend
ht=irf_legend(gca,[mfilename ' ' char(datetime("now","Format","dd-MMM-uuuu HH:mm:ss"))],[0.02 1.01], 'interpreter','none','fontsize',8);
%
% labels a),b)...
help irf_pl_number_subplots
%
% if you want some alternative colorbars, like white in middle, blue negative and red positive
% or if you want to use different colorbars within the same figure
help irf_colormap
%
%% Second axis
%
hl1 = line(x1,y1,'Color','r');
ax1 = gca;
%
ax2 = axes('Position',get(ax1,'Position'));
set(ax2,'XAxisLocation','top','xtick',[]); % remove 'xtick' if xticks required
set(ax2, 'YAxisLocation','right');
set(ax2,'Color','none'); % color of axis
set(ax2,'XColor','r','YColor','r'); % color of axis lines and numbers
%
%___________________________________________
% Another example
%
t=irf_time([2008 03 01 10 0 0]):.2:irf_time([2008 03 01 11 0 0]);

% define one time series
y=exp(0.001*(t-t(1))).*sin(2*pi*t/180);
