gridmore.m

% You create a graph and you do "grid on", but you want more of those major
% grid lines at certain values of the axis, without these values getting
% labeled: This function makes it happen. Especially interesting when data
% is not a continous but a discrete set (like "years"), so that the command
% "grid minor" is not appropriate. Tested in MATLAB2010b and MATLAB2016a.
% (I) USE AFTER "GRID ON"
% (II) s must be a string: 'x', 'y' or 'z' (the desired axis)

% Example 1:
% After creating a graph and doing "grid on", we want more lines
% at certain values of the x-axis. We save all the x-values we want
% with a grid line in a matrix "X". We do:

% >>gridmore(X,'x');

% Example 2:
% We are going to make different graphs and we want the same grid on
% the x-axis in all of them. We do, e.g., for the first figure:

% >>plot(A,B);
% grid on
% [xlabels]=gridmore(X,'x');

% For the following figures, don't call the function again; use the
% output argument "xlabels":

% >>plot(C,D);
% grid on
% set(gca,'Xtick',X,'XTickLabel',xlabels)

% How does gridmore.m work?
% XTick, YTick and ZTick are the location of the tick marks and major
% grid lines for each axis. XTickLabel, YTickLabel and ZtickLabel are the
% labels for each tick mark. The function increases the number of ticks
% labeling new ticks with an empty label.
