For all panels, the inset displays the avalanche-size pdf <i>P</i> (<i>y</i>; <i>L</i>) vs. the avalanche size <i>y</i>.

<p>The large figures show the data collapse obtained by plotting the transformed avalanche-size pdf <i>y</i>^τ<i>P</i> (<i>y</i>; <i>L</i>) vs. the rescaled avalanche size <i>y</i>/<i>L</i>^<i>D</i> using the estimates of the avalanche-size scaling exponents τ and <i>D</i> obtained from moment scaling analysis, see Tables <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142685#pone.0142685.t001" target="_blank">1</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142685#pone.0142685.t002" target="_blank">2</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142685#pone.0142685.t003" target="_blank">3</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142685#pone.0142685.t004" target="_blank">4</a>.
