I have the following requirement where there are some plots which will be stacked in two columns as shown in the figure. And in addition there is a color bar which will be placed on the right side vertically. Could you help me achieve that in latex ?
Thanks in advance
PS : I tried with subfigure environmment with \usepackage{subcaption} and \usepackage{caption}. This is not working because of the \usepackage{subfig} already present in the preamble, which I use it also for stacking figures into multiple columns in a different place in the document.
