<h5>Max data points</h5>
<ul>
<li>Every graphite request is issued with a maxDataPoints parameter</li>
<li>Graphite uses this parameter to consolidate the real number of values down to this number</li>
<li>If there are more real values, then by default they will be consolidated using averages</li>
<li>This could hide real peaks and max values in your series</li>
<li>You can change how point consolidation is made using the consolidateBy graphite function</li>
<li>Point consolidation will effect series legend values (min,max,total,current)</li>
<li>If you override maxDataPoint and set a high value performance can be severely effected</li>
