GwyGraphArea is the central part of GwyGraph widget. It plots a set of data curves with the given plot properties.
It is recommended to use it within GwyGraph. However, it can also be used separately.
void gwy_graph_area_set_model (GwyGraphArea *area
,GwyGraphModel *gmodel
);
Sets the graph model of a graph area.
GwyGraphModel *
gwy_graph_area_get_model (GwyGraphArea *area
);
Gets the model of a graph area.
void gwy_graph_area_set_x_range (GwyGraphArea *area
,gdouble x_min
,gdouble x_max
);
Sets the horizontal range a graph area displays.
void gwy_graph_area_set_y_range (GwyGraphArea *area
,gdouble y_min
,gdouble y_max
);
Sets the vertical range a graph area displays.
void gwy_graph_area_set_x_grid_data (GwyGraphArea *area
,guint ndata
,const gdouble *grid_data
);
Sets the grid data on the x-axis of a graph area
void gwy_graph_area_set_y_grid_data (GwyGraphArea *area
,guint ndata
,const gdouble *grid_data
);
Sets the grid data on the y-axis of a graph area
const gdouble * gwy_graph_area_get_x_grid_data (GwyGraphArea *area
,guint *ndata
);
Gets the grid data on the x-axis of a graph area.
const gdouble * gwy_graph_area_get_y_grid_data (GwyGraphArea *area
,guint *ndata
);
Gets the grid data on the y-axis of a graph area.
GwySelection * gwy_graph_area_get_selection (GwyGraphArea *area
,GwyGraphStatusType status
);
Gets the selection object corresponding to a status of a graph area.
A selection object exists even for inactive status types (selection modes), therefore also selections for other modes than the currently active one can be requested.
The selection type is GwySelectionAxis for point-wise selections along axes GWY_GRAPH_STATUS_XLINES
and
GWY_GRAPH_STATUS_YLINES
.
The selection type is GwySelectionRange for range selections along axes GWY_GRAPH_STATUS_XSEL
and
GWY_GRAPH_STATUS_YSEL
.
The selection type is GwySelectionPoint for the point-wise selection GWY_GRAPH_STATUS_POINTS
.
The selection type is GwySelectionRectangle for the zoom mode GWY_GRAPH_STATUS_ZOOM
(which is generally handled
internally by the graph).
area |
A graph area. |
|
status |
Graph status. Passing |
The requested selection. It is NULL
only if status
is GWY_GRAPH_STATUS_PLAIN
and the current
selection mode is GWY_GRAPH_STATUS_PLAIN
.
void gwy_graph_area_set_status (GwyGraphArea *area
,GwyGraphStatusType status
);
Sets the status of a graph area.
When the area is inside a GwyGraph, use gwy_graph_set_status()
instead
(also see this function for details).
GwyGraphStatusType
gwy_graph_area_get_status (GwyGraphArea *area
);
Gets the status of a grap area.
void gwy_graph_area_enable_user_input (GwyGraphArea *area
,gboolean enable
);
Enables/disables auxiliary graph area dialogs (invoked by clicking the mouse).
Note, however, that this setting does not control editability of selections.
Use gwy_graph_area_set_selection_editable()
for that.
void gwy_graph_area_set_selection_editable (GwyGraphArea *area
,gboolean setting
);
Enables/disables selection editing using mouse.
When selection editing is disabled the graph area status type determines the selection type that can be drawn on the area. However, the user cannot modify it.
void gwy_graph_area_edit_curve (GwyGraphArea *area
,gint id
);
Invokes the curve property dialog for a curve plotted in a graph area.
If the dialog is already displayed, it is switched to the requested curve.
void gwy_graph_area_coords_widget_to_real (GwyGraphArea *area
,gdouble xscr
,gdouble yscr
,gdouble *x
,gdouble *y
);
void gwy_graph_area_set_natural_size (GwyGraphArea *area
,gint width
,gint height
);
Sets the preferred natural dimensions of a graph area.
Graphs can be very small, but have relatively large default (natural) dimensions. Since GTK+ tries to make windows large enough for the natural widget sizes, it does not work well when they are used as small preview plots in dialogs. This function allows setting the natural size arbitrarily.
The minimum size is not changed (and is very small by default). Use gtk_widget_set_size_request()
to set a minimum
size.
“status”
property“status” GwyGraphStatusType
The type of reaction to mouse events (zoom, selections).

“edit-curve”
signalvoid user_function (GwyGraphArea *gwygraphcurvemodel, int arg1, gpointer user_data)
The ::data-changed signal is emitted when a curve properties are to be edited.
gwygraphcurvemodel |
The GwyGraphArea which received the signal. |
|
arg1 |
The index of the curve to edit. |
|

user data set when the signal handler was connected. |
