Dear ROOTers, I have a question regarding TGraph; I've made a graph containing 4096 datapoints, it draws perfectly, can be fitted, etc. However, when I want to Get a Point on the Graph with GetPoint(int, double&,double&) it returns data as expected BUT ONLY UP TO SIZE/2 !! Doe anybody have a clue as to why this happen? Below I've added a transcript of a ROOT session (the x-values in the graph range from -1000 to +1000) Thanks inadvance !! root [27] graphfp.Dump(); fNpoints 4096 Number of points *fX -1000 [fNpoints] array of X points *fY 2.7376 [fNpoints] array of Y points *fFunctions ->5457f0 Pointer to list of functions (fits and user) *fHistogram ->54b2f0 Pointer to histogram used for drawing axis fMinimum -1111 Minimum value for plotting along y fMaximum -1111 Maximum value for plotting along y fName ->54587c object identifier fName.*fData Graph fTitle ->545884 object title fTitle.*fData fUniqueID 0 object unique identifier fBits 50332680 bit field status word fLineColor 1 line color fLineStyle 1 line style fLineWidth 1 line width fFillColor 1 fill area color fFillStyle 1001 fill area style fMarkerColor 1 Marker color index fMarkerStyle 1 Marker style fMarkerSize 1 Marker size root [28] graphfp.GetPoint(2048,min,max); root [29]min (double)0.00000000000000000e+000 root [30] root [31] graphfp.GetPoint(2047,min,max); root [32] min (double)(-4.88281250000000000e-001) root [33]
