I have two questions, 1, I want to modify the space between the title and plot; 2, I do not know how to specify a font style and size of colobar tick in the subplot; It demand me to post more detail about my quesiton, I do not know what I should I provide. so better to ask a quesion. Why is it very slow when I add the save: plt.savefig("Fig01.png",dpi=1000, bbox_inches='tight') It will cost many time to save, and I can not get the pdf version. I do not why. and I think the color in my plot is not so good. where can I find more color?
