[ROOT] TF1::Draw() with error bars

Dear Rooters,

Could somebody let me know how to draw a function (pol1 for example) with
error bar? 

Suppose we get a function "pol1" by fitting from a histogram. If I try
with TF1::Draw("e"), "e" is just my guess to plot error bars, it gives a
correct center line, but error bars are not the one from fit parameter.

Ciao,
Inkyu
