* clear trafficgraph on clear button click * set default sample height set default sample height so after clearing traffic graph have some scale * reduce available traffic graph ranges, add optimized graph data storage reduce available traffic graph ranges to 10 (5m,10m,15m,30m,1h,2h,3h,6h,12h,24h), store graph data so range change is possible, data storage contains only necessary data to create graphs for all supported ranges eg. for 10m range storage only half of 10m samples - the second half is calculated from 5m range samples, encapsulate all traffic graph related data into one class * code formatting corrections
