 Subject: add line w/o changing limits From: Assaf Weinstein Date: 7 Jul, 2010 09:46:03 Message: 1 of 5 Hi, How do I add a line to an existing figure, without changing xlim, ylim? What I would use is set(gca, 'xlim',xlim(gca), 'ylim',ylim(gca)) before adding the line.. Is there any better way to do this? Thanks, Assaf

This sets the XLimMode, YLimMode, and ZLimMode properties to manual. ----------------------------------------- Maxim Vedenev, MATLAB Custom Programming vedenev@ngs.ru http://simulations.narod.ru/

You are mistaken. The original poster's code would have worked.  >> figure(123);t = plot(exp(1:5)); ax = get(t,'Parent'); disp(get(ax,'XLimMode'));set(ax,'XLim',[0 2]);disp(get(ax,'XLimMode')); auto manual http://www.mathworks.com/access/helpdesk/help/techdoc/ref/axes_props.html#XLimMode XLimMode, YLimMode, ZLimMode      {auto} | manual      MATLAB or user-controlled limits. The axis limits mode determines whether MATLAB calculates axis limits based on the data plotted (for example, the XData, YData, or ZData of the axes children) or uses the values explicitly set with the XLim, YLim, or ZLim property, in which case, the respective limits mode is set to manual. The direct mechanism for the original poster would be to set(gca,'XLimMode','manual','YLimMode','manual')

Although this property has a high practical use and is existing for many years, it could be removed in a future release. Good luck, Jan
