在matplotlib中,可以使用`set_aspect`方法来设置等值线图的轴比例尺。该方法可以接受一个参数`aspect`,用于指定轴比例尺的值。 轴比例尺是指图形中x轴和y轴的比例关系,它决定...
解决这一问题的方法是在执行plt.draw()之后,但在开始处理转换之前添加一个set_aspect。下面的代码使用p...
我们可以使用matplotlib.axes.Axes.set_aspect() 函数设置长宽比。如果在函数中使用等于作为长宽比,则得...
要设置Matplotlib中轴的范围和比例,可以使用set_xlim()和set_ylim()方法来指定轴的范围,使用set_aspect()方法来设置轴的比例。 例如,要设置x轴范围为0到10,y轴范围为0到20,并且x和y轴的比例为1(即x轴和y轴单位长度相等),可以按照以下步骤操作: import matplotlib.pyplot as plt # 创建一个图形对象 fig, a...
Controls the aspect ratio of the axes. The aspect is of particular relevanceforimages since it may distort the image, i.e. pixel willnotbe square. This parameter is a shortcutforexplicitly calling`.Axes.set_aspect`. See thereforfurther details. ...

set_aspect only works (e.g. to draw round spheres) if it is accompanied by setting the 3 axis limits to be the same. If the axis limits are different then the drawing is distorted with or without use of set_aspect; this is the “rectangular coordinates problem” mentioned previously. ...
