## METHODS

### widget = Gtk2::Curve-\>new

### $curve-\>set\_curve\_type ($type)

- •

  `$type` (Gtk2::CurveType)

### $curve-\>set\_gamma ($gamma)

- •

  `$gamma` (double)

### $curve-\>set\_range ($min\_x, $max\_x, $min\_y, $max\_y)

- •

  `$min_x` (double)

- •

  `$max_x` (double)

- •

  `$min_y` (double)

- •

  `$max_y` (double)

### $curve-\>reset

### list = $curve-\>get\_vector ($veclen=32)

- •

  `$veclen` (integer)

Returns a list of real numbers, the curve's vector.

### $curve-\>set\_vector (...)

- •

  ... (list) of float's, the points of the curve

## PROPERTIES

- 'min-x' (float : default 0 : readable / writable / private)

  Minimum possible value for X

- 'min-y' (float : default 0 : readable / writable / private)

  Minimum possible value for Y

## SIGNALS
