Why X-axis values change after saving the figure in .jpeg or .tif format? How can I rectify it?

I am using time on my x-axis and some data on y-axis. Code is given below:

dataset=[1 2 .... 144]; % Any array of 144 points
t = duration(1/6:1/6:24,10,0,'Format','hh:mm');
plot(t,dataset);

it gives a plot shown in the first figure however when I try to save it in .jpeg or .tif format it automatically changes the x-axis to show all values giving all the values on top of each other?

Which MATLAB release are you using, and which operating system?

How are you saving to file?

When you print(), then the figure properties PaperPosition and PaperPositionMode are used. If a small PaperPosition were in use, then because the font size is fixed, the characters could end up jammed together.

Walter Roberson I am using R2015a and windows 10 I am saving the file using "save as" option in the figure dialog box once the figure is plotted and I have changed the size of figure from "export setup" to width=3.42inch height=3inch. I am selecting .tif format to save. You are right. Is there a way to specify only selected points that gets shown on x-axis manually? so that they don't get jammed when I save the figure in a small size.

Found the solution using set(gca,'XTick',[0 1/6 1/3 1/2 2/3 5/6 1]) I was able to obtain xticks at selected point. Thank you Walter Roberson for your valuable insight.
