Hi Roy,
I have a dataset where missing data points are represented by "-1".
I use DeleteCases to delete these entries before plotting.
data =
{{0, 0.17`}, {0.0417`, -1}, {0.0834`, -1}, {0.5834`,
0.2768`}, {1, -1}, {1.5`, 0.3009`}, {2, -1}, {2.5`, 0.5531`}, {3,
0.4356`}, {3.5834`, 0.9192`}, {4, 0.8432`}, {4.5`, 0.8502`}, {5,
1.5065`}, {5.5`, 1.3061`}, {6, 2.6049`}, {6.5`, 3.4581`}, {7,
3.351`}, {7.5`, 2.674`}, {8, 4.142`}, {8.5`, 3.4166`}, {9,
4.5047`}, {23.6667`, 4.943`}, {23.9167`, 4.1904`}};
DeleteCases[data, {_, -1}]
Regards,
Bernd

Does anyone have a Mathematica routine that behaves like ListPlot with
PlotJoined->True, where the data have missing values (given by a set
number, or if preferred by being out of range) and only joins
non-missing values. Assume the listis long (500-600 points) and there
may be quite a few (100-200) missing values. Such a routine wouldbe a
big help.
TIA,
Roy M.
