Share. 00000]) This set command creates 6 tics in X axis, but I like to create 20 ticks so that there are 50 elements in between 2 tics. properties if you applied datetick to the y- or z-axis. Adam appears to be using an older version of MATLAB, but combined with Orion's solution it gave me the idea that led to me fixing my problem. set(gca, 'YTick', [0. Create a scatter plot and rotate the tick labels along each axis. A "handle" is a kind of address to identify all graphic objects. Then set the XTick property using dot notation, such as ax. . To change the font size, set the FontSize property on the axes object after plotting. However when I get my figure the order of the numbers on the axis are wrong, for example on X axis it. 05:1]*512, 'YTickLabel', [0:0. Color; ax. 75 25. NOTE: for MATLAB R2014b and later you will have to use new line character instead of the | symbol. add two "helping - lines", one solid and one dotted. It is helpful, but may not be necessary in your final code. Yes. set (gca, 'YTickLabel', []) This way the tick marks are still there. if it's 2 hours that would be 121 values [0:120]' if the origin is at 00 minutes--if not use the desired offset.

MinorTicks. When I use set(gca,'XTick',-pi:pi/2:pi). To reverse an axis, you can set the 'XDir' or 'YDir' property of the current axes to 'reverse': set (gca,'XDir','reverse'); %# This flips the x axis. 1 Answer. Copy. For example, assign the Axes object to a variable, such as ax = gca. yaxisproperties= get. 하는 김에 보기 좋게 그래프 선도 조금 두껍게 만들어 보아요. XTick = [-3*pi -2*pi -pi 0 pi 2*pi 3*pi]. Sign in to comment.
