Matplotlib savefig does not save the full plot in the output

Question

I'm making visualisations and when i save plots i don't get the full plot in my output.

My plots are limited by 24 hours, in the image bellow there is only the part between [20:40,00:00]

i fixed a figsize of (155,3) and DPI = 300

i know that the size is high, DPI too, but i need that.

How can i save figures and getting full plot on the output.

PS : if i reduce the figsize and the DPI it works but i need to get it with that figsize.

Thanks.
