Hey all, 

In APEX 19.1, I've created a stacked area chart.  In between each series
is a white border that I'd like to remove, but I can't find a way to
hide it in the APEX interface.  In the resulting HTML of the APEX page,
it looks like the chart is rendered using SVG.  The element that creates
the border is a polyline like: 

<polyline points="11.2 320 ..." fill="none" stroke="#FFFFFF"
stroke-width="1.25"></polyline> 

Since the stroke color and width are hard-coded, I thought I'd try
adding this to the Appearance->CSS Classes section of the chart region: 

polyline: { style="stroke-opacity:0" } 

..but that has no effect.  That bit of CSS doesn't show up in Firefox's
inspector, so that seems to point to me doing something wrong. 

Thoughts, anyone?
Rich
