#set_size_mode(size_mode, width, height) ⇒ nil

Sets the size mode of the GOGraph::Widget. It is used to determine the size and position of the drawn chart. The following sizing modes are supported:

GO_GRAPH_WIDGET_SIZE_MODE_FIT, aspect ratio set. The aspect ratio is guaranteed to be maintained, i.e. the graph is never squeezed, and will always fit into the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT, no aspect ratio set. The aspect ratio is adapted to make the graph exactly fit into the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT_WIDTH, aspect ratio set. The aspect ratio is guaranteed to be maintained, i.e. the graph is never squezzed, and will always occupy the whole width of the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT_HEIGHT, aspect ratio set. The aspect ratio is guaranteed to be maintained, i.e. the graph is never squezzed, and will always occupy the whole height of the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT_FIXED_SIZE, no aspect ratio set. The graph will occupy the area specified by width/height, its aspect ratio will be determined by height/width.

Parameters:

• size_mode (GOffice::GraphWidgetSizeMode) —

  GOGraph::WidgetSizeMode

• width (Integer) —

  in pixels

• height (Integer) —

  in pixels

Returns:

• (nil)

#vres ⇒ Float
