SubPlot, Multiple axis

Once I have created six graphs, how do I make them the same size? They get smaller, as each subplot. Thank you.https://plot.ly/~cyunker/29/?share_key=ThqyzXqXOzzilzfr1Ya2bE

Setting all x-axis domain values to have equal span should do the trick. For example,

layout.xaxis.domain = [0, 0.3]
layout.xaxis2.domain = [0.35, 0.65]
layout.xaxis3.domain = [0.7, 1]
