The TGraphMultiErrors painting is performed thanks to the TGraphPainter class. All details about the various painting options are given in this class.

The picture below gives an example:

◆ Apply()

void TGraphMultiErrors::Apply ( TF1 * f )

Only the first error dimension is affected.

Special treatment has to be applied for the functions where the role of "up" and "down" is reversed.
