Equivalent to matlab's imagesc in matplotlib?
提问by Matt
I am coming to Python and numpy and matplotlib from a Matlab background. One function in matlab that I use all the time is imagesc. Is there an exact equivalent to this somewhere in matplotlib? I know about imshowand pcolor, but the first doesn't allow you to easily set the units of the axes like imagesc, and the second makes you set the x- and y-coordinates of the boundaries of the pixels, rather than the centers of the pixels, which I do not find intuitive.
我从 Matlab 背景来到 Python、numpy 和 matplotlib。我一直使用的 matlab 中的一个函数是imagesc. 在 matplotlib 的某处是否有与此完全相同的内容？我知道imshowand pcolor，但第一个不允许您轻松设置轴的单位，例如imagesc，第二个让您设置像素边界的 x 和 y 坐标，而不是像素的中心，我觉得这不直观。
Basically, if I have an image that I want to display with x- and y-axis labels that are not pixel numbers but are numerical, like distance in mm, what is the easiest way to do it in matplotlib?
基本上，如果我想用 x 轴和 y 轴标签显示图像，这些标签不是像素数而是数字，例如以毫米为单位的距离，那么在 matplotlib 中最简单的方法是什么？

You want the extentkwarg
你想要extent夸格
ax.imshow(data, extent=[0, 1, 0, 1])
See Imshow: extent and aspectfor a more detailed example.
有关更详细的示例，请参阅Imshow：范围和方面。
