This is another case where the regular Mathematica graphics paradigm, based on somewhat adaptable set-piece plots, can get you all tangled up. I have no idea why ListPlot does not display the Tooltips. It appears that it generates them and then throws them away when rendering the overall plot. It does work if you Map the Tooltips onto the individual points. Perhaps it is a bug that WRI will fix. It is much easier to draw directly what you want and specify the directives you need for each portion of the graphic. So with Presentations: Needs["Presentations`Master`"] Draw2D[ {AbsolutePointSize[4], ListDraw[Tooltip[Range[4], "Data1"]], Dashed, Red, ListDraw[Tooltip[Range[4]/2, "Data2"], Joined -> True]}, AspectRatio -> .6, Axes -> True] The tooltips are there, on both the points and the line. For the log plots: logticks = CustomTicks[Log, {-1, 2, {1, 1.5, 2, 3, 5} // N, {4, 6, 7, 8, 9}}]; Draw2D[ {Thick, ListLogDraw[Tooltip[Range[4], "Data1"], Joined -> True], Thin, Dashed, Red, ListLogDraw[Tooltip[Range[4]/2, "Data2"], Joined -> True]}, AspectRatio -> .6, PlotRangePadding -> Scaled[.05], Frame -> True, FrameTicks -> {{logticks, logticks // NoTickLabels}, {Automatic, Automatic}}] David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: dr DanW [mailto:dmaxwarren at gmail.com] I have been trying to write a fully functional legend function for the Plot family of functions. I have been baffled by some inconsistencies between the behavior of ListPlot and the other plotting functions, about which I have posted previously on this forum. To wit: ListLogPlot[ Tooltip [ Range[4], "Data" ] ] ] works as expected, but ListPlot[ Tooltip [ Range[4], "Data" ] ] ] looses the tooltip. Also, ListLogPlot[ { Range[4], Range[4]/2 } , Joined->True, PlotStyle-> {Thick, Dashed} ] gives you a solid thick line and a thin dashed line, whereas ListPlot[ { Range[4], Range[4]/2 } , Joined->True, PlotStyle->{Thick, Dashed} ] gives you a solid thick line and a thick dashed line. These inconsistencies have challenged my faith in Mathematica. However, through much experimentation I have discovered that ListLinePlot is a rewritten version of ListPlot (similar to ListLogPlot being a rewritten version of LogListPlot.) As far as I can tell, ListLinePlot has behavior that is consistent with the other plotting functions. The only nagging difference is that, by default, Joined->True, but we know how to deal with that. I suspect that ListPlot should have been put on a deprecated function list but was not. So, my suggestion is to get into the habit of using ListLinePlot instead of ListPlot. Daniel
