Hello, I have two unrelated questions: 1. LISTPLOT When I execute the following command the result is a listplot where the data points ares fairly big filled black circles. In[1]:= ListPlot[{0,2,4,9,16,25},PlotStyle->PointSize[0.05]] The following gives a plot where the data points are joined by a line. In[2]:= ListPlot[{0,2,4,9,16,25},PlotJoined -> True] With the following I would expect the combination of the two. It does however give the same results as In[2]: the "PlotStyle->PointSize[0.05]" options doesn't seem to have any effect here. Is this intended behaviour or is this a bug? In[3]:= ListPlot[{0,2,4,9,16,25},PlotJoined -> True, PlotStyle->PointSize[0.05]] Is there a way you can have both options "PlotJoined -> True" and "PlotStyle->PointSize[0.05]"? 2. NOTEBOOK DIRECTORY Is there a command which gives the directory where the current notebook resides? You get the notebook directory -- which can be some network directory different from the local directory where Mathematica is located -- with $InitialDirectory when you start Mathematica by double clicking on the notebook file in Explorer (Windows). However, when Mathematica is launched from the programs menu and you open the same notebook from the File menu, $InitialDirectory gives the Mathematica directory. Is there a command which also in the latter case gives the path to the notebook? I did not find anything in the book. This would be very usefull when you want to read in data from an ascii file which sits in the same directory as the notebook file. It would make moving the whole directory much easier: you would not have to retype a fairly long network directory path. Thanks for any help Maarten van der Burgt Icos Vision Systems Leuven Belgium
