 If you don't know JavaScript and still want to help us by reporting a bug, please attach the `"data"` and `"layout"` attributes that describe your graph and updates (if required to detect the bug). One way to retrieve your graph's data and layout attributes is by exporting your graph to [Plotly Cloud](http://plot.ly/). To do so, click on the _Edit in Chart Studio_ mode bar button (the 2nd one from the left by default) and follow these [instructions](https://help.plot.ly/save-share-and-export-in-plotly/), or watch this [screencast](https://community.plot.ly/t/mega-sharing-graphs-with-chart-studio/8869).
