Python 带链接轴的PyQtGraph网格
使用PyQtGraph进行简单的图形布局,其中绘图的x轴链接在一起,网格也显示在两个绘图中:Python 带链接轴的PyQtGraph网格,python,pyqt,pyqtgraph,Python,Pyqt,Pyqtgraph,使用PyQtGraph进行简单的图形布局,其中绘图的x轴链接在一起,网格也显示在两个绘图中: from pyqtgraph.Qt import QtGui, QtCore import pyqtgraph as pg app = QtGui.QApplication([])
from pyqtgraph.Qt import QtGui, QtCore
import pyqtgraph as pg
app = QtGui.QApplication([])
view = pg.GraphicsView()
l = pg.GraphicsLayout()
view.setCentralItem(l)
view.show()
view.resize(800,600)
p0 = l.addPlot(0, 0)
p0.showGrid(x = True, y = True, alpha = 0.3)
#p0.hideAxis('bottom')
p1 = l.addPlot(1, 0)
p1.showGrid(x = True, y = True, alpha = 0.3)
p1.setXLink(p0)
l.layout.setSpacing(0.)
l.setContentsMargins(0., 0., 0., 0.)

if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):
QtGui.QApplication.instance().exec_()
如果我在第一个绘图中隐藏x轴(取消注释代码中的p0.hideAxis('bottom')
行),则轴将消失,但网格也将消失:
我怎么能强迫它呆在那里?由于两个x轴都链接在一起,我希望这是可能的(上部绘图中的网格可以取自下部绘图的x轴)。不要隐藏轴,请尝试
axis.setStyle(showValues=False)
(这可能只在开发分支中可用)因此,这是一个完整的代码,包含以下修改:

from pyqtgraph.Qt import QtGui, QtCore
import pyqtgraph as pg
app = QtGui.QApplication([])
view = pg.GraphicsView()
l = pg.GraphicsLayout()
view.setCentralItem(l)
view.show()
view.resize(800,600)
p0 = l.addPlot(0, 0)
p0.showGrid(x = True, y = True, alpha = 1.0)
#have no x-axis tickmark below the upper plot (coordinate 0,0)
#without these lines, there will be separate coordinate systems with a gap inbetween
ax0 = p0.getAxis('bottom') #get handle to x-axis 0
ax0.setStyle(showValues=False) #this will remove the tick labels and reduces gap b/w plots almost to zero
#there will be a double line separating the plot rows
p1 = l.addPlot(1, 0)
p1.showGrid(x = True, y = True, alpha = 1.0)
p1.setXLink(p0)
l.layout.setSpacing(0.)
l.setContentsMargins(0., 0., 0., 0.)

它工作得很好,但是当使用
showValues=False
时,分隔AxisItem和ViewBox的行仍然存在。当使用hideAxis
时,有没有办法摆脱它?谢谢。。。对于其他试图实现此功能的用户,您还需要使用axis.showLabel(False)
@pev.hall隐藏标签。在最新版本中,您不需要使用showLabel设置任何内容。如果您选择showLabel(True),则将创建标签空间,但该空间将为空,因此使用showValues=False时,默认情况下showLabel为False。
