# Moving a subfigure

I need to move the left part of the subfigure in the following picture upward:

That is, the image should like the following:

so the subfigures are aligned vertically at the top.

Don't use subfigure as it is deprecated. Use subcaption or subfig instead. I used subcaption. You can level the baselines appropriately to keep the images at same levels.
