For more control over the precise tick mark locations, an alternative workaround is available in MATLAB releases beginning with R2009a that uses a callback function for a zoom mode object. If I use set(gca,'xtick',[]) the ticks vanish as expected, but the exponent, common for all ticks, remains in the plot at the end of the axis. Asking for help, clarification, or responding to other answers. MATLAB generally goes for 4 to 5 tick labels automatically, with an algorithm for determining which ticks might be "nice" based upon the data values. Example 1 'Label x-Axis Ticks with 2-digit Years' on the datetick page in the 2014b documentation says you need to convert an array to 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.

I would like to have a tick mark every 5 years for example. I'd like to use imagesc to plot a matrix with distance on y axis, z in colorbar, and datetime on x axis. The 'ticklabel' property writes the text on existing tick marks wherever they're located and in whatever number they already exist, either wrapping the text over if fewer text entries than ticks just ignoring extra entries if more strings than the number of ticks are passed. My best guess is that the format is only showing the year, but datetick has chosen ticks that are not exactly one year apart.
