How **can we improve our confidence? **virtual voidFitPanel () Display a GUI panel with all graph fit options. More... Note: The above two methods are only available for the 2D plot (including polar graph) and the 3D XYY plot, but not for the 3D Surface, 3D Bars and 3D Scatter useful reference

If you look back at the line graph above, we can now say that the mean impact energy at 20 degrees is indeed higher than the mean impact energy at 0 Bool_t TGraphErrors::CtorAllocate ( void ) protected Constructor allocate. The option "SAME" By default, when an histogram is drawn, the current pad is cleared before drawing. Bool_tGetEditable () const Return kTRUE if kNotEditable bit is not set, kFALSE otherwise.

When the error bars icon is selected, an Error Bar tab displays on the right side of the dialog box. virtual voidSetPoint (Int_t i, Double_t x, Double_t y) Set x and y values for point number i. When one changes the current style and would like to propagate the changes to the histogram, TH1::UseCurrentStyle should be called. I know the options but the problem is when I try to combine them together.For example, "h->Draw("e1c")" doesn't produce the effect I desire, i.e.

Since what we are representing the means in our graph, the standard error is the appropriate measurement to use to calculate the error bars.

Instead of a simple bar chart, these histograms will (by default) look more like a graph when plotted, with the value of each bin shown as a marker with an error Once a histogram is painted, the statistics box can be accessed using h->FindObject("stats").
