Hi! Just a short question: Consider a dataset which looks somewhat like this: 409.00000 0.2875184 0.0251621804162307 421.00000 1.08303395 0.0488355952731649 [...] That is x-value, y-value and the error estimated. Now this error is symmetric, but I wrote some general function to plot errors which uses TGraphAsymErrors(). Just setting xlow and xhigh to the same value. It seems root doesn't like my data. Especially not the 0.x errors. I get a fine plot of the data line but no error bars. Now if I multiply this two colums by a constant so that the errors are .gt. 1 I get nice error bars. Did I miss something in the docs or is it intended for the error-graphs to deal only with errors .gt. 1? Well I solve my problem just by multiplication which is in a way ok with me at the moment. Maybe I made a dumb mistake somewhere? -- Kind regards, / War is Peace. | Freedom is Slavery.
