How to make lines thinner in a graph?

Hello.

Here is a screenshot of my problem: http://imagizer.imageshack.us/a/img844/6378/ej4z.png

I made a graph with thousand of points, but the lines which make the curves are too thick and so I can't see exactly where they intersect. I would like to make them thinner.

Thanks in advance for your answers.

I've already tried that. When I try to decrease the size there's a Microsoft Excel message which says this:
"L'affichage de la mise en forme complexe appliqué au graphique sélectionné risque de prendre du temps. Voulez-vous continuer à utiliser la mise en forme ?"
Which could be roughly translated in English by:
"The display of complex formatting applied to the selected chart/graph may take some time. Do you want to continue using the formatting?"
And then when I click on "Yes" and decrease the size it does nothing.


PS: I've tried to change the language in Excel to English but it doesn't work...
