title: Editing content of legend in TeeChart
body: <p>Is it possible to programatically edit teh legend in a TeeChart, so the variables called with the left axis and right axis can be distinguished. To illustrate:</p>
  
  <p>If I am plotting three series p, q, and r, and p and q use VertAxis := aLeftAxis, while r uses VartAxis := aRightAxis, then in the legend I want to group p, and q under a left axis heading and r under a right axis heading. Alternately, two separate legends would suffice to do the same job. Teh default behavior of TeeChart is to group all variables in the same legend without distinction.</p>
