Is it possible to change the axis titles for line charts? I can do so with column charts
<option name="charting.secondaryAxisTitle.text">Usage in bytes</option>
But the same options appear to have no affect on line charts. For instance, the x axis, "Time" is shown as the splunk field _time.
Guess I spoke too soon. I changed the search query, saved it, and that triggered something in splunk that refreshed the graph and make the axis labels appear.
