Hey @kac53211, try upgrading iRuby to the latest version (or at least >= 0.7.1). It's due to this issue: https://github.com/SciRuby/iruby/issues/314

[kac53211]

Thank you, I will try that now and report back

[kac53211]

Brilliant, that did it. I updated to iruby-0.7.4 and now the bar chart is displaying as expected. Thank you so much for the quick response!

[ankane]

Great!
