I want to reproduce this graphic using tkz-base and tkz-euclide :graphic

But I strugle to print the Y axis on the left, as all the x's are negative.

Here's a MWE :


All I have is :


As you can see, the y axis is on the right while I want it on the left.

  • Might I suggest using PGFplots? As far as I know tkz-euclide is more designated to geometric drawings. And your plot seems to be quite easy with PGFplots... Jan 18, 2017 at 16:58
  • @GuilhermeZanotelli The tkz collection also has tkz-fct for plotting stuff. The \tkzAxe stuff is defined in tkz-base. Mar 5, 2017 at 10:42

I don't know how to modify the tkz stuff to do that, but as mentioned in a comment pgfplots is a good package for plotting stuff. Here is a starting point:

enter image description here

  % set axis limits
  % draw axis lines only on left and bottom (default is to make a box)
  axis y line=left,
  axis x line=bottom,
  % disable having a common scale factor for all ticklabels
  scaled x ticks=false,
  % separation between ticks on x-axis
  xtick distance={50000},
  % number of minor ticks
  minor x tick num=4,
  % disable having e.g. -1e5 as a tick
  xticklabel style={/pgf/number format/fixed}

% plot some random numbers, just for example
\addplot +[domain=-150000:0] {rnd*10 + 4};

If you really want to stick with tkz-base then the only way [that I can find] to do this is to reset your axes to be positive, and then put the labels in by hand.

    \tkzInit[xmin=0, xmax=150000, xstep=10000, ymin=4, ymax=18, ystep=2]
    \tkzDefPoint( 50000,3.8){A}\tkzLabelPoint[below](A){$-100\,000$}

enter image description here

Of course, if you do this you would need to adjust your data points so that the years are positive too. I guess you can think of them as "years since 150,000 years ago". But as noted in the comments, you might find it easier to use pgfplots.
