我有一个代码，可以从用户那里获取数据并制作 Excel 表格。 对于每个组，它应该制作自己的工作表，并将其用于“文本”数据。 但它并没有用图像来实现，而是将第一圈的图像放入每个工作表中。 此外，经过所有圈数后，它会删除图像，但我认为这不会成为问题。 这就是代码：

x_ind = np.arange(x)
workbook = xlsxwriter.Workbook('Registers.xlsx')
for i in range(num):

a2 = int(input('Input Min: '))
a3 = int(input('Input Max: '))

问题在于程序正在使用同名文件覆盖“Registers.png”图像。 XlsxWriter 在文件/工作簿关闭之前不会读取图像，此时图像已被覆盖。
解决方案是为每个唯一的图像指定一个唯一的名称，如下所示：
# ...
image_name = f"registers{i}.png"
plt.savefig(image_name)
row += 2
