confusionchart maximization in subplots

I have 23 different machine learning algorithms extracted from the classification learner toolbox. I am trying to plot all the confusioncharts for all 23 in one plot using subplots, but I need to increase the size of the confusioncharts in each subplots so that I can see the numbers. Here is the for loop used to plot the confusioncharts, how can I make it bigger in each subplot so that I can see the numbers?
