<answer>

// xunc & yunc mean 5% of the total size of the graph.  So xunc is 5% of 20, and yunc is 5% of 16.  dyunc is (ymax-ymin)/(xmax-xmin) and dy2unc is (ymax-ymin)/(xmax-xmin)^2.
<rule initial="0" final="0" y="3" xunc="5%" yunc="5%"/>
<rule initial="-10" final="0" dy=">0" xunc="5%" />
<rule initial="-10" final="0" dy2="0" xunc="5%" dy2unc="10%"/>

<rule segment="1" beginsearch="0" dy="<0" endtrigger="dy=0"/>
<rule segment="2" beginsearch="segment1.endtrigger" dy="0" endtrigger="dy!="0" dyunc="10%"/>
