python xarray刻度标签大小问题

Question

我是 xarray 和 cartopy 的新手。我想问一下如何增加/减少 x-/y- 刻度上的标签大小。以下是我的代码。fig = plt.figure(figsize=(18,8)) ax  = plt.axes(projection =ccrs.PlateCarree())   ax.add_feature(cartopy.feature.LAND,facecolor='wheat') ax.add_feature(cartopy.feature.OCEAN) ax.add_feature(cartopy.feature.STATES, linestyle='-',lw=1.0,edgecolor='white') ax.add_feature(cartopy.feature.BORDERS, linestyle='-',lw=2.5,edgecolor='white') gp = ds.isel(time=0).gpm.plot.pcolormesh('lon','lat',ax=ax,             infer_intervals=True,vmin=0,vmax=1600,cmap='jet',extend='both') ax.coastlines(resolution='50m',color='white') ax.add_feature(cartopy.feature.RIVERS) gl = ax.gridlines(color='gray',alpha=0.6,draw_labels=True) gl.xlabels_top, gl.ylabels_right = False, False ax.yaxis.tick_right() ax.set_ylim([18,32]) ax.set_xlim([-100,-77])  ax.set_title('GPM Accumulated Rain (12Z Aug24 - 12Z Aug31)', fontsize=16) ax.set_aspect('equal') ax.tick_params('both',labelsize=30) plt.show()       我已经添加了tick_params来设置labelsize，但是字体的大小仍然是默认大小。同时，谁能告诉我如何将颜色条标签移动到颜色条标题？
