Get Shorter legend names

• alias() function to specify a custom series name
• aliasByNode(2) to alias by a specific part of your metric path
• groupByNode(2, 'sum') is useful if you have 2 wildcards in your metric path and want to sumSeries and group by.

Series as parameter

• Some graphite functions allow you to have many series arguments
• Use #[A-Z] to use a graphite query as parameter to a function
• Examples:
  • asPercent(#A, #B)
  • divideSeries(#A, #B)

If a query is added only to be used as a parameter, hide it from the graph with the eye icon

Max data points

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