plotly rangeslider how to restore the limit bar on the slider
<p>I have a rangeslider with slided limits, I need to redraw the slider with
the grey part like this.<a href="http://i.stack.imgur.com/be1yR.png" rel="nofollow"> rangeslider example </a></p>

<p>If I save the range values from the layout and restore it, it affects the
xaxis range for both the top and bottom, so it is not right. Perhaps
something like limit-range?</p>
