title: Is there any way to change the color of the label on a Plot.ly JavaScript
body: <p>On the graph in the JSBin link below, which is generated with Plotly (<a href="https://plot.ly/javascript/" rel="nofollow">https://plot.ly/javascript/</a>), when you hover over the bar chart 'bars', the values associated with each bar are displayed - however the text color corresponds to the color the bar is set to and is unreadable if a light color.</p>

  <p>So essentially, when hover of the Giraffes Bar items, is it possible to change the color or bgcolor of the hover values of "SF Zoo" that is displayed?</p>
