All the charting functions return a Chart instance. From this you can change various attributes of the chart, such as ticks, labels, and axes. Only a subset of Plotly's capabilities are implemented here so if you can't find something, take a look at the Plotly API. If you think it would be useful for others, it may be good to expose it here. Consider contributing a pull request or letting me know that it would be useful!
