First issue
I added a horizontal line to my stacked bar graph I got from here:
However, if I put in a number like 10 for the series[4].Line.Appearance.dashedarray
then I get an error, but the line is dashed.
If I put in the string, then a solid line appear instead of the line.
I generated my line as a column with values 65%. It is set as a series.
Here is an image of the line stopping too soon across the graph at the end.
Third issue
Seems that my lines between are the same color as the bottom bar in my stacked bar graph.
I kind of want that to be black.
