Set thickness of chart legends' line

[hose]

Hi!

I want to ask, how to change the line thickness of the chart legend? I realy can't find the option. I can change the font size, the background, shadow, everything, but not the line thickness.
I've attached a screen shot, what am talking about:

Is it possible to do it at all?

Thanks in advance!

From the Graph menu, click Legend. The Graph legend options dialog box appears.

In the Legend location area, click Overlay.

When you select the legend position, the text in the lower half of the window changes depending on the selected location position.

In the Overlay legend area, specify the Size and Position of the legend.

The size and position of the legend are set as a percentage of the graph screen size. This allows automatic adjustment when the size of the window is changed.

A Position of 70 30 places the top left corner of the legend 70% of the screen height down from the top and 30% of the screen width from the left edge. A Size of 20 30 sets the height of the legend box to 20% of the screen height and the width to 30% of the screen width.

Choose a Text color, Background color, and Highlight color.

Highlight color is used when you change the shape of the graph and change the underlying data by choosing to allow mouse data input.

Set the Edge thickness.

Click OK.
