So right now I have something like this:

enter image description here

As you can see, the xticks on the second (smaller) plot are a complete mess. Is it possible to just show 3 values (the first, midpoint and last ones)?

Secondly, is it possible to place something like a ~ or // break symbol at the beginning of the smaller plot, as it just shows the last 10 values of the bigger plot?

  • Can you include the code to arrive to this plot?

  • the (presumably) negative notations $-10^{13}$ and $-10^9$ should really be entirely in math mode so that there's a real minus sign, not ha hyphen. (i've edited the title to spell "omit" correctly, so it can be found with a search.) Jul 17, 2013 at 16:14
  • Usually PGFPlots will not place the tick labels this close together, it looks like you changed some options that lead to the overlapping. Could you edit your question to include the code for the axis?

To add axis discontinuity use axis option axis x discontinuity=crunch|parallel|none (only one of the three, your choice) as explained in pgfplots manual at page 123.

With option xtick of the axis environment you can choose what ticks to show, just type them inside brackets in xtick={} and separate them with ,.

    You can also add the \xticklabels={} list to specify the labels of the ticks you select with \xtick={}.
