There was a default argument padding in the setYRange which is set to either 0. 02 or 0. Long answer: In class ViewBox, method setLimits calls method 因此，Pyqtgraph会自动计算轴并在缩放时重新缩放，这很好。然而，我有两个轴，频率和小时。频率可以是0-100之间的任何值，小时可以是0-39之间的任何值。如何将轴限制在这些上下限，以便用户在缩放或平移时不能超出这些值？我的代码如下(对于3行代码，我的实际代码将绘制更多内容)：from pyqtgraph PlotItem中的显示区域是一个viewbox，通过pyqtgraph库源码查看： self. setConfigOption ('imageAxisOrder', 'row-major') Use C-contiguous image data. ViewBox# class pyqtgraph. addLegend()向它添加了一个图例。我的问题是，图例只显示来自轴1的项，如何让它显示来自所有轴的数据？我得到的是： 图例中没有显示的每一行都与 I need to select and get data of two graphics from plots, I found a example, where it is created a custom viewbox and then create a plot like that pw = pg. html.

So I've modified the class's code from my Python Site Packages folder. For 1 or 3 channel data, use uint8, Fast data visualization and GUI tools for scientific / engineering applications - pyqtgraph/pyqtgraph That said, I've not studied pyqtgraph classes in depth, so I don't know for sure how its focus management works, but if you need a "global" keyboard handling, you should probably use a GraphicsLayoutWidget subclass and implement the keyPressEvent() in it, then eventually check if the given point is within the boundaries of the viewbox before What's the unit of measure? Is it pixels? Percentage? Short answer: The unit of measure of scaling limits is the same as the panning limits. 边框border: PyQtGraph is a pure-python graphics and GUI library built on PyQt / PySide and numpy. vb = viewBox. __init__ (parent = None, useOpenGL = None, background = 'default',) [source] # Arguments: parent. argv) # construct a QApplication (must).
