      Thanks! That's the reason indeed!<br>
      <br>
      The workarounds do work but with pitfalls. With xstring() the
      label moves around when zooming in or out, and xlabel takes too
      much space, in fact saving space was the reason to place it only
      on the last plot. <br>
      <br>
    </font><font face="Courier New">Probably </font><font face="Courier
      New">it would be possible to adapt the coordinates x, y for
      xetring to the bounds of the axes, but I'm not sure the positions
      would be updated when interactively zooming.<br>
      <br>
      The desired behavior would be that by default all plots would be
      the same size or that it would be possible to place a label
      relative to a figure<br>
      <br>
      Regards,<br>

                <div>Hi Federico,</div>
                <div><br>
                </div>
                <div>my best guess:   In your example only
                  subplot(4,1,4) gets the x_label</div>
                <div>Since this needs space, the diagram is smaller.</div>
                <div><br>
                </div>
                <div>Workaround:    create label for x-axis via xstring</div>
                <div><br>
                </div>
                <div>Or: <br>
                </div>
                <div><br>
                </div>
                <div>Assign a x_label for each subplot, but hide it.</div>
                <div>
                  This will assign "space" for the label, but it won't
                  be displayed...hence all diagrams should look the
                  same...
