• Give more control on the axis titles:
  • Position: inside/outside

           ^
           |
Y(outside) | Y(inside)
           |
           |     X(inside)
           o----------------->
                 X(outside)

• • Position min/middle/max

       Y(max)   ^
                |
                |
                |
      Y(middle) | 
                |
                |
       Y(min)   o------------------------------->
                X(min)     X(middle)           X(max)

• • Rotation: horizontal/vertical/oblique/auto/3D

> threshold ? Vertical : Horizontal

3D: text orientation = axis orientation

• • Label font size:
    • Fixed (in px)
    • Relative to Viewport (see vtkTextActor)
    • Relative to Axes
  • ?Spacing between label and axes?
    • Adjust the positions of the Y labels so that they don't overlap with the chart
  • Style:italic/bold/shadow/color/?antialiasing?...
• Feature: Add a grid 9007
• Feature: Add more axis ticks 9007
• Support subscripts:
  • how ?
    • ?Qt overlay?
  • FTGL currently supports Unicode fonts
