GLLinePlotItem

class pyqtgraph.opengl.GLLinePlotItem(**kwds)[source]

Draws line plots in 3D.

__init__(**kwds)[source]

All keyword arguments are passed to setData()

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 vertex 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) or tuple of floats specifying a single color for the entire item.
width float specifying line width
antialias enables smooth line drawing
mode
‘lines’: Each pair of vertexes draws a single line
segment.
‘line_strip’: All vertexes are drawn as a
continuous set of line segments.
