Using the Epilog option it would be something like this: ProbabilityScalePlot[{data1, data2, data3}, "Weibull", PlotRange -> Automatic, GridLines -> Automatic, GridLinesStyle -> "Classic", FrameLabel -> {{Style["Ausfallwahrscheinlichkeit F(t) in %", Italic, FontSize -> 12], ""}, {Style["Lebensdauer", Italic, FontSize -> 12], ""}}, Frame -> True, Epilog -> {Black, Thick, Line[{{Log[0.001], 0.05}, {Log[60], 0.05}}]}] But the value, 0.05, is only an approximate value. WRI does not tell us enough about the underlying plot coordinates, and I don't know enough about probability distributions. David Park djmpark at comcast.net http://home.comcast.net/~djmpark/index.html From: Martin Palatini [mailto:martin.palatini at googlemail.com] Hello, I got a big problem with my ProbabilityScalePlot. I want to plot a simple, horizontal line in my diagramm. This diagramm shows a weibull plot. In this weibull plot are shown three different weibull distribution functions. At the value of 63.21% on the y-axis, i want to plot this simple horizontal line. This line symbolize the characteristic lifetime of a component. I don't get it. Please help me, i need this plot for my master thesis. The code for the plot is called: data1 = RandomVariate[WeibullDistribution[1, 1], 100]; data2 = RandomVariate[WeibullDistribution[1, 10], 100]; data3 = RandomVariate[WeibullDistribution[1, 2], 100]; ProbabilityScalePlot[{data1, data2, data3}, "Weibull", PlotRange -> Automatic, GridLines -> Automatic, GridLinesStyle -> "Classic", FrameLabel -> {{Style["Ausfallwahrscheinlichkeit F(t) in %", Italic, FontSize -> 12], ""}, {Style["Lebensdauer", Italic, FontSize -> 12], ""}}, Frame -> True] P.S. My english isn't so good, but i hope you understand me.
