Exporting as any bitmap style (gif, png, jpg) will have the same resolution as your
monitor, and if not used at the same zoom, the bitmap will look bad. JPG files are
even worse, due to their poor rendering of sharp color transitions.

Where are the charts being used? If you are moving them into another program, try
copying in Excel as a picture, using the On Screen and As Picture options, then
paste into the target app. This copies the chart as the set of shapes that comprise
it, and these can be scaled continuously without the pixelation that spoils bitmaps.

What is the method to export Excels charts so that they
have the best possible appearance?

Default graphs in Excel show curves as line segments (jagged) that are
clearly visible. No graphic smoothness!

Is there any solution to control what is the resolution of the chart you
export in "gif" file?? My own solution is to enlarge the chart in excel
before exporting and then, reduce the size of the gif with photoshop. This
solution does not give good results. Any idea ??
Nota: I'm using office xp with the last updates.
Thanks,
