Details

class GOffice.GraphChartMap

classmethod new(chart, area, axis0, axis1, axis2, fill_area)

Parameters:

• chart (GOffice.GraphChart) – a GOffice.GraphChart
• area (GOffice.GraphViewAllocation) – area allocated to chart
• axis0 (GOffice.GraphAxis) – 1st dimension axis
• axis1 (GOffice.GraphAxis) – 2nd dimension axis
• axis2 (GOffice.GraphAxis) – 3rd dimension axis
• fill_area (bool) – does chart GOffice.fill allocated area

Returns:

a new GOffice.GraphChartMap object.

Return type:

GOffice.GraphChartMap

Creates a new GOffice.GraphChartMap, used for conversion from data space to canvas space.

free()

Frees self object.

get_axis_map(index)

Parameters:index (int) – axis index Returns:a GOffice.GraphAxisMap. Return type:GOffice.GraphAxisMap

Convenience function which returns one of the associated axis_map.

Valid values are in range [0..2].

get_polar_parms()

Returns:a GOffice.GraphChartMapPolarData struct. Return type:GOffice.GraphChartMapPolarData

Convenience function for retrieving data related to polar plot layout.

is_valid()

Returns:True if self is valid. Return type:bool

Tests if self was correctly initializied, i.e. if all associated axis_map are valid (see GOffice.GraphAxisMap.is_valid() ).

given to GOffice.GraphChartMap.new.

make_close_path(x, y, n_points, fill_type)

Parameters:

• x (float) – x data
• y (float) – y data
• n_points (int) – number of points
• fill_type (GOffice.GraphSeriesFillType) – GOffice.fill type

Returns:

a new GOffice.Path using x and y data, with respect to fill_type.

Return type:

GOffice.Path

make_path(x, y, n_points, interpolation, skip_invalid, data)

Parameters:

• x (float) – x data
• y (float) – y data
• n_points (int) – number of points
• interpolation (GOffice.LineInterpolation) – interpolation type
• skip_invalid (bool) – whether to ignore invalid data or interrupt the interpolation
• data (object or None) – a user pointer

Returns:

a new GOffice.Path using x and y data, each valid point being connected with respect to interpolation.

Return type:

GOffice.Path

view_to_2D(x, y, u, v)

Parameters:

• x (float) – data x GOffice.value
• y (float) – data y GOffice.value
• u (float) – placeholder for x converted GOffice.value
• v (float) – placeholder for y converted GOffice.value

Converts a 2D coordinate from canvas space to data space.
