Reports :: Microsoft Chart Object In Report - Formatting Line Weights

Using a Microsoft Chart Object 6.0 in an Access 2010 report. It's easy enough to do the basics and that chart responds to data.In my case, I have 12 lines, or columns, being controlled by data. It responds to the data. just fine. What I want to do is control the line weight and colour of each line through VBA.

You can click on the chart itself on the report form, but formatting the line you actually want is almost impossible. Pretending we can, you get the pop-up configuration windows and the TAB "PATTERNS". Under that, you can select "LINE" and then choose the style, color and weight. This is what I need to do in VBA.

Lines like this do not work:Graph_Data.Columns("A").Line.Weight = 5
or...
objDataSheet.Columns("A").Line.Weight = 5I tried a variety of versions of that and am pulling my hair out.
