1、 Python设置colorbar单位

ticks=[10,30,50,70,90,110]
cf=ax.contourf(olon,olat,PM25,levels=ticks,cmap=cmaps.NCV_bright,transform=ccrs.PlateCarree(),extend='both')
# 白化contourf
clip1=maskout.shp2clip(cf,ax,'./henan1')
cbar=plt.colorbar(cf,shrink=0.96,orientation='vertical',pad=0.01,aspect=35,extend='both')
font3={'family':'SimHei','size':16,'color':'k'}
ax1=cbar.ax#召唤出cb的ax属性并省称为ax2,这时ax2即视为一个子图
cbar.set_ticks([20,40,60,80,100])
ax1.tick_params(labelsize=16,right=True)#修改刻度样式，并使左右都有刻度
ax1.set_yticklabels(['小雨','中雨','大雨','暴雨','特大暴雨'],fontdict=font3)
cbar.ax.tick_params(labelsize=16,direction='in',right=False,labelcolor='blue')

 

 
cbar.set_ticks([10,30,50,70,90,110])
ax1.tick_params(labelsize=16,right=True)#修改刻度样式，并使左右都有刻度
ax1.set_yticklabels(['小雨','中雨','大雨','暴雨','特大暴雨','超大暴雨'],fontdict=font3)
cbar.ax.tick_params(labelsize=16,direction='in',right=False,labelcolor='red')

 
ticks=[10,20,30,40,50,60,70,80,90,100]
cbar=plt.colorbar(cf,orientation='vertical',pad=0.01,aspect=35,shrink=0.96,ticks=ticks,extend='both')
#为色标加标注
font2={'family':'SimHei','size':16,'color':'k'}
cbar.set_label('频次',fontdict=font2)
cbar.ax.tick_params(labelsize=16)

cbar.set_ticks([20,30,40,50,60,70,80,90])
cbar.set_ticklabels(['20 times','30 times','40 times','50 times','60 times','70 times','80 times','90 times'])

2、Python设置colorbar刻度

cbar.ax.tick_params(labelsize=16, direction='in',length=18,width=1.6,color='k')

 
cbar.ax.tick_params(labelsize=16, direction='in', right=False)

 

cbar.ax.tick_params(labelsize=16, direction='out',length=6,width=2,color='k')

 

3、Python设置坐标轴刻度

 
# 以下6条语句是定义地理坐标标签格式
ax.set_xticks(np.arange(leftlon, rightlon+0.1, 1),crs=ccrs.PlateCarree())
ax.set_yticks(np.arange(lowerlat, upperlat+0.1, 1),crs=ccrs.PlateCarree())
lon_formatter = LongitudeFormatter()
lat_formatter = LatitudeFormatter()
ax.xaxis.set_major_formatter(lon_formatter)
ax.yaxis.set_major_formatter(lat_formatter)
ax.tick_params(color='k', direction='in',length=6,width=2)
