Hi Rene,

Sorry for bothering again with small details. With your fix the upper script is now at a upper postion but maybe not sufficiently high. See the title of the following example :

{
        TH1F *h = new TH1F("h", "^{18}F + ^{18}F", 100, 0, 100);
        h->Draw();
}

It is not the case for the lower script.

Thanks again
