Serialaxes

• Get the state names with

  set states [$s info states]
  dict keys $states

• Query a state, say sequence, as follows

  $s cget -sequence

• Change a state, say again sequence, as follows

  $s configure -sequence {stearic linoleic palmitic arachidic}

  

• When creating a plot you may specify any state at plot creation

  set s1 [serialaxes -data $olive -color $Area -title "olive data"\
      -sequence [lrange [dict keys $olive] 2 end]]

• details on a state, say sequence, is easily had with

  set states [$s info states]
  dict get $states sequence

  and a particular field

  dict get $states sequence description

Good To Know

• The serialaxes display does not support zooming and panning.
• Sweep selection is with a line and not with a rectangle.

Data Scaling

The scaling state defines how the data is scaled. The axes display 0 at one end and 1 at the other. For the following explanation assume that the data is in a nxp dimensional matrix. The scaling options are then

• variable: per column scaling.
• observation: per row scaling.
• data: whole matrix scaling.
• none: do not scale.
