does anyone know how to chnage a line in a line chart making one end an arrow
and making the entire line very thick (thicker than Excel allows in the drop
down box)

Thanks

does anyone know how to chnage a line in a line chart making one end an arrow
and making the entire line very thick (thicker than Excel allows in the drop
down box)

This can be done with a macro, by drawing a polygon shape over the line chart
series. With little explanation, the code is given below. The chart must be a line
chart with a category, not time scale, axis.

In the block of code that begins with

With myShape.Line

you can change the color, line weight, dash style, and arrow configuration of this
added polygon shape. Beware of line wrap in the posted code.
