Data module
- class lys.widgets.canvas.interface.Data.CanvasData(canvas)[source]
Bases:
CanvasPart- Append(wave, axis='BottomLeft', appearance={}, offset=(0, 0, 0, 0), filter=None, contour=False, vector=False)[source]
Append Wave to graph.
Data type is determined by the shape and dtype of wave in addition to contour and vector.
When 1-dimensional data is added, line is added to the graph.
When 2-dimensional real data is added and contour is False, image is added.
When 2-dimensional real data is added and contour is True, contour is added.
When 2-dimensional complex data is added and vector is False, it is converted to RGB colormap data.
When 2-dimensional complex data is added and vector is True, it is added as vector map.
When 3-dimensional data is added and its shape[2] is 3 or 4, it is added as RGB(A) color map data.
See
Line.LineData,Image.ImageData,Contour.ContourData,Vector.VectorData,RGB.RGBDatafor detail of each data type.- Parameters
wave (Wave) – The data to be added.
axis ('BottomLeft', 'BottomRight', 'TopLeft', or 'TopRight') – The axis to which the data is added.
appearance (dict) – The dictionary that determins appearance. See
WaveData.saveAppearance()for detail.offset (tuple of length 4) – See
WaveData.setOffset()filter (filter) – See
WaveData.setFilter()contour (bool) – See above description.
vector (bool) – See above description.
- Remove(obj)[source]
Remove data from canvas.
- Parameters
obj (WaveData) – WaveData object to be removed.
- dataChanged
pyqtSignal that is emittd when data is added/removed/changed.
