Hello! I am working with signals and a plot of several signals on the same axes can get quite messy. With lines that are very fractured, distinction by only the linestyle is not very clear. If I add symbols to the plot however, there are so many symbols, that they overplot and the whole plot is unreadable once again. I am looking for advice on how to make a plot with continuous lines and symbols appearing at every nth point. An example of this problem and a solution in SAS can be found here: www2.sas.com/proceedings/sugi26/p072-26.pdf
The obvious solution would be to extract the n-th point from the dataset and overplot as a new line with symbols, but this does not change the legend, does it? How can I then have a line+symbol in the legend represent my curve? Now, ideally I would prefer a solution in ggplot, because of the ease of plotting and changing the plot labels and other properties. However, I remember, Hadley mentioned that he is still working on a new version to have combined line+symbol plots, and probably he hasn't finished that yet. So any advice is welcome. Regards, TL PS. I did RTFM and I am not posting code, because at this time I expect a general outline how to do it and what commands to lookup, not code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
