Hi,
Png in better than jpeg if you want a bitmap format. Cheers,

Save as JPEG and then convert the image to GIF outside of ROOT. GIF format is known to have some limitations (256 colors) and problems (patent issues, which are largely resolved now, but still..)

Or perhaps you can use PNG format? That's more universal these days.

Of course the best practice is to save as Encapsulated Postscript (vector graphics), and then convert to bitmaps (JPEG, PNG, GIF) whenever

you need a specific representation of your plot. This way you never lose

any resolution, and are also able to make minor changes to the plot outside ROOT - like changing axis names, or labels.

Cheers,
Stefan.
