Sharing Y-Axis Range for Multiple Horizontal Bar Charts ============================================= Pandas bar plotting doesn’t always work intuitively. This makes sharing axes quite complicated. One problem is that the bars don’t get a numerical nor a pure categorical tick position. Instead, the bars are numbered 0,1,2,... and afterwards the ticks get their label. Another problem is that bars for a numerical column can get a weird conversion to string (e.g. a value 12.

Understanding Xcode 4’s Organizer and iTunes Connect As a developer, working with Apple products can sometimes seem like navigating a complex web of tools and services.
