"layout-updated" void user_function (GwyGraphCurveModel *gwygraphcurvemodel, gpointer user_data);
GwyGraphCurveModel represents information about a graph curve necessary to fully reconstruct it. It will be meaningfully used by the new generation of graph widgets and should be mostly ignored for now.

#define gwy_graph_curve_model_duplicate(gcmodel)
Convenience macro doing gwy_serializable_duplicate() with all the necessary typecasting.
gcmodel : | A graph curve model to duplicate. |
GwyGraphCurveModel* gwy_graph_curve_model_new (void);
Creates a new graph curve model.
With current generation of graph widgets it is useless without gwy_graph_curve_model_save_curve().
Returns : | New empty graph curve model as a GObject. |
void gwy_graph_curve_model_set_data (GwyGraphCurveModel *gcmodel, gdouble *xdata, gdouble *ydata, gint n);
Sets curve model data. Curve model does not make a copy of the data, therefore you should not free the data unless you know what are you doing.
gcmodel : | A GwyGraphCurveModel. |
xdata : | x data points (array of size n) |
ydata : | y data points (array of size n) |
n : | data array size (number of data points) |
void gwy_graph_curve_model_set_data_from_dataline (GwyGraphCurveModel *gcmodel, GwyDataLine *dline, gint from_index, gint to_index);
Sets the curve data from GwyDataLine. The range of import can be modified using parameters from_index and to_index that are interpreted directly as data indices within the GwyDataLine. In case that from_index == to_index full GwyDataLine is used.
gcmodel : | A GwyGraphCurveModel. |
dline : | A GwyDataLine |
from_index : | index where to start |
to_index : | where to stop |
void gwy_graph_curve_model_set_description (GwyGraphCurveModel *gcmodel, gchar *description);
Sets curve model description. The description should appear on graph label, for example.
gcmodel : | A GwyGraphCurveModel. |
description : | curve description text |
void gwy_graph_curve_model_set_curve_type (GwyGraphCurveModel *gcmodel, GwyGraphCurveType type);
Sets curve type for plotting the curve. This includes setting points, linespoints, line, etc.
gcmodel : | A GwyGraphCurveModel. |
type : | curve type |
void gwy_graph_curve_model_set_curve_point_type (GwyGraphCurveModel *gcmodel, GwyGraphPointType point_type);
Sets curve point type for plotting the curve. Curve type that is chosen must include some kind of point plot to see any change (e. g. GWY_GRAPH_CURVE_POINTS).
gcmodel : | A GwyGraphCurveModel. |
point_type : | point type to be used for plot |
void gwy_graph_curve_model_set_curve_point_size (GwyGraphCurveModel *gcmodel, gint point_size);
Sets curve point size for plotting the curve. Curve type that is chosen must include some kind of point plot to see any change (e. g. GWY_GRAPH_CURVE_POINTS).

color : | GwyRGBA color structure (will not be directly used) |
const gdouble* gwy_graph_curve_model_get_xdata (GwyGraphCurveModel *gcmodel);
Gets pointer to x data points. Data are used within the graph and cannot be freed.
gcmodel : | A GwyGraphCurveModel. |
Returns : | x data points |
const gdouble* gwy_graph_curve_model_get_ydata (GwyGraphCurveModel *gcmodel);
Gets pointer to y data points. Data are used within the graph and cannot be freed.
gcmodel : | A GwyGraphCurveModel. |
Returns : | y data points |
gint gwy_graph_curve_model_get_ndata (GwyGraphCurveModel *gcmodel);
gcmodel : | A GwyGraphCurveModel. |
Returns : | number of data points within the curve data |
gchar* gwy_graph_curve_model_get_description (GwyGraphCurveModel *gcmodel);
gcmodel : | A GwyGraphCurveModel. |
Returns : | curve data description (what appears as curve label on graph) as newly allocated string. |
GwyGraphCurveType gwy_graph_curve_model_get_curve_type (GwyGraphCurveModel *gcmodel);
gcmodel : | A GwyGraphCurveModel. |

void gwy_graph_curve_model_signal_layout_changed (GwyGraphCurveModel *model);
Emits signal that somehing general in curve layout (plotting style) was changed. Graph widget or other widgets connected to graph model object should react somehow.
