Glitch in Google Charts API

[KJ]

Hello! 

I'm currently creating a bar chart using Google Charts API. It's a horizontal bar chart that displays the string labels vertically. If I render the graph on a browser, it displays fine. However, I have a button that hides the graph initially. Once I click the button, the graph displays, this time without the labels. I'm not sure why this is happening, and there doesn't seem to be this issue from other users online. I'm also wondering if it's possible to display $ symbols with the tick marks on the horizontal axis. Currently, it seems that the bar chart only accepts numerical inputs. Any ideas on what to do? 

Thanks!
