Add a comment. 1 Answer. For example, when you type datenum (‘9,15,2014’) and press Enter, you get an output value of 735857. etc. One could use 'normalized' units but then have to compute where the x-positions needs must be--a Catch-22 conundrum; to be totally general one needs must compute one or the other; your choice as to which. . This allows you to set a given group of properties to different values on each object. example. xt = get (gca, 'XTick'); set (gca, 'XTickLabel', 2. set(gca, 'xtick', xtk, 'xticklabel', tklbl); A second option would be to pass the plot some datetime values as x-data, so that Matlab will add a date axis to the plot and take care of formatting the tick labels. yt = get (gca,'ytick'); for j=1:length (yt) % With log plots, MATLAB defaulted to exponential format, that is difficult for lay. set (gca, 'Units', 'centimeters') So if ax. ylim (2),maxLabel); or define how many labels should. If XTick is set by the user, this property is automatically set to manual. You want to set your XTick values before you set your XTickLabels since you are constructing your XTickLabels from the values of the XTicks themselves. 01,100000]); ylim ( [0,1]); % call the axes information corresponding to xlim and ylim, ax = gca; % set them to empty. x = linspace (0,10); y = sin (4*x); plot (x,y) Set the font size, tick direction, tick length, and y -axis limits for the current axes. Setting the tick positions after calling datetick() would not work: datetick() sets the tick labels to strings, and those strings would not be reflect the positions you set afterwards. TickLength = [1, 0. Create a line plot. Contents. Find the treasures in MATLAB Central and discover how the community can help you!
