RE: linestyle and gridlines

[William Krekeler]

Chris,

You're right, it is hard to get to the grid line properties. Here is a work 
around that will break if you zoom in on the graph so you'll have to update it 
each time the graph axis changes.


xLocations = get( gca, 'XTick' );
yExtent = get( gca, 'YLim' );
h2 = zeros( 1, length(xLocations) );
% don't modify first or last because at edge of the graph
% better code would test that xLocations(1) and (end) are == XLim property
% I leave that to you to fix
for nX = 2:(length(xLocations) -1 )     
   GridLine = yExtent(1):(diff(yExtent)/100):yExtent(2);
   hold on, h2(nX) = plot( repmat( xLocations(nX), 1,numel(GridLine) ), 
GridLine, 'r--' ), hold off
end

% use the handle h2 to modify the grid lines to your heart's content

For nX = 2:(length(h2) -1 )
   Set( h2(nX), 'PropertyName', 'PropertyValue' );
end

I'm trying to make the lines inside the box thicker, the lines that show
up when you type the command grid on.
