我们从Python开源项目中，提取了以下5个代码示例，用于说明如何使用pyqtgraph.setConfigOption()。
def test_plotscene(): tempfilename = tempfile.NamedTemporaryFile(suffix='.svg').name print("using %s as a temporary file" % tempfilename) pg.setConfigOption('foreground', (0,0,0)) w = pg.GraphicsWindow() w.show() p1 = w.addPlot() p2 = w.addPlot() p1.plot([1,3,2,3,1,6,9,8,4,2,3,5,3], pen={'color':'k'}) p1.setXRange(0,5) p2.plot([1,5,2,3,4,6,1,2,4,2,3,5,3], pen={'color':'k', 'cosmetic':False, 'width': 0.3}) app.processEvents() app.processEvents() ex = pg.exporters.SVGExporter(w.scene()) ex.export(fileName=tempfilename) # clean up after the test is done os.unlink(tempfilename)
def __init__(self, parent=None): pyqtgraph.setConfigOption('background', 'w') #before loading widget super(ExampleApp, self).__init__(parent) self.setupUi(self) self.grECG.plotItem.showGrid(True, True, 0.7) self.btnSave.clicked.connect(self.saveFig) self.btnSite.clicked.connect(self.website) stamp="DIY ECG by Scott Harden" self.stamp = pyqtgraph.TextItem(stamp,anchor=(-.01,1),color=(150,150,150), fill=pyqtgraph.mkBrush('w')) self.ear = swhear.Ear(chunk=int(100)) # determines refresh rate # optionally you can manually set the audio input device to use like this: # self.ear = swhear.Ear(chunk=int(100), device=5) # use audio input device 5 if len(self.ear.valid_input_devices()): self.ear.stream_start() self.lblDevice.setText(self.ear.msg) self.update()
