使用matplotlib和wxpython在另一个面板中显示来自NetCDF的像素值？

import wx
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
from netCDF4 import Dataset

app = wx.App()
frame = wx.Frame(None, title="NetCDF Pixel Values", size=(800, 600))
panel = wx.Panel(frame)

nc_file = Dataset('path/to/netcdf/file.nc', 'r')
data = nc_file.variables['variable_name'][:]
nc_file.close()

fig = plt.figure(figsize=(8, 6))
ax = fig.add_subplot(111)

# 绘制像素值
ax.imshow(data, cmap='jet', origin='upper')

# 可选：添加颜色条
cbar = plt.colorbar(ax.imshow(data, cmap='jet', origin='upper'), ax=ax)
cbar.set_label('Pixel Values')

# 可选：添加地图背景
map = Basemap(projection='cyl', llcrnrlat=min_lat, urcrnrlat=max_lat, llcrnrlon=min_lon, urcrnrlon=max_lon, resolution='l')
map.drawcoastlines()
map.drawcountries()

# 可选：添加其他图形元素或标注

# 显示图形
plt.show()

canvas = FigureCanvas(panel, -1, fig)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(canvas, 1, wx.EXPAND)
panel.SetSizer(sizer)
panel.Layout()

frame.Show()
app.MainLoop()
