无法在Python中生成正确的图

因此，我一直在尝试在python中生成一个热图，以使生成的matplotlib图在x和y轴上都没有任何白色边缘，并且相对于x和y轴单元，图形的缩放率必须为1：1。我已经尝试了很多事情，但是到目前为止，我能够取得的最佳成就就是能够删除X轴白色边缘，而不是Y的边缘。这是一个例子：这就是我得到的：这就是我想要的：

这是我生成图表的代码：

plt.style.use('classic')
plt.axis('equal')
plt.pcolormesh(x_mesh,y_mesh,intensity)
plt.plot(x,y,linestyle="None",marker='.',markerfacecolor='white')
#plt.colorbar()
#plt.axis('off')
plt.margins(x=0,y=0)
plt.ylim([0,254])
plt.xlim([0,538])
plt.savefig('plottest.png', dpi=144, bbox_inches='tight', pad_inches=0)
plt.show()

任何帮助都将不胜感激！谢谢！

So I have been trying to generate a heatmap in python such that the Matplotlib graph that is generated does not have any white margins in both x and y axes and the graph's scaling must be 1:1 with respect to the x and y axes units. I have tried many things but the best I have been able to achieve so far is able to remove the x axis white margins but not the y one. Here's an example:
This is what I am getting:

This is what I want:

Here's the code through which I am generating the graph:

plt.style.use('classic')
plt.axis('equal')
plt.pcolormesh(x_mesh,y_mesh,intensity)
plt.plot(x,y,linestyle="None",marker='.',markerfacecolor='white')
#plt.colorbar()
#plt.axis('off')
plt.margins(x=0,y=0)
plt.ylim([0,254])
plt.xlim([0,538])
plt.savefig('plottest.png', dpi=144, bbox_inches='tight', pad_inches=0)
plt.show()

Any help would be highly appreciated! Thanks!
