However when I get my figure the order of the numbers on the axis are wrong, for example on X axis it. To prevent MATLAB from changing the tick locations or number of ticks when the figure is resized or printed, change this property to manual. Then set the XTick property using dot notation, such as ax. Stack Overflow. In this page, I would post a quick reference for Matlab and Octave. MATLAB's built-in function datetick also performs similarly. Create a line plot. So you have to add another fake bar using nan and adjust the x-axis. I guess this behavior is due to the fact that MATLAB does not assign any label to non-visible ticks. I can give any specific array of 4 numbers to matlab to set the position but they are not interpreted correctly and Matlab seems to just randomly change the position of the legend a bit. Thanks! the set(gca,'XTick') works when you use plot but doesn't work for a heatmap object. close all x = linspace(0,4*pi); y = sin(x); plot(x,y)Learn more about axis, axes, matlab .

These define where the grid lines are when grid is on. You can use set(gca, 'TickDir', 'out'). and the x-axis values should start from top left towards right side (that means 0 should come in top left side and 140 should come in the top right side). 'gca' means 'get current axis' You can set parameters of the graph using 'set' set(gca, 'xtick', [0, pi/2, pi]); Change xtick labesl set(gca, 'xtickLabel', {'0', '0.
