pyqtgraph.opengl.
GLScatterPlotItem
(**kwds)[source]¶ Draws points at a list of 3D positions.

initializeGL
()[source]¶ Called after an item is added to a GLViewWidget. The widget’s GL context is made current before this method is called. (So this would be an appropriate time to generate lists, upload textures, etc.)
-
paint
()[source]¶ Called by the GLViewWidget to draw this item. It is the responsibility of the item to set up its own modelview matrix, but the caller will take care of pushing/popping.
-
setData
(**kwds)[source]¶ Update the data displayed by this item. All arguments are optional; for example it is allowed to update spot positions while leaving colors unchanged, etc.
Arguments: pos (N,3) array of floats specifying point locations. color (N,4) array of floats (0.0-1.0) specifying spot colors OR a tuple of floats specifying a single color for all spots. size (N,) array of floats specifying spot sizes or a single value to apply to all spots. pxMode If True, spot sizes are expressed in pixels. Otherwise, they are expressed in item coordinates.
