If psymi 8, then the procedure usersym is called with vertices define in the keyword usersym. If psymi is negative, then a line connects pts for ith item.

The bars of the histogram plot are filled. I usually prefer to fill the histogram bars, like this. This is what can be done with the cgHistoplot command from the Coyote Library. These commands will produce a plot like this. If this keyword is a string, the name of the symbol color. SYMCOLOR in optional typestring/integer defaultblack.

With this short program and the same data you are using, youД¬an make a histogram plot with this IDL code. Any normal IDL PSYM values, plus any value supported by the Coyote Library routine cgSYMCAT. The histogram plots in theД¬oyote Plot Gallery were written with theД¬gHistoplot program from the Coyote Library. eps file is larger than the IDL plot window, although the aspect ratio is correct. The /buffer keyword sends the plot to a buffer rather than the screen. I notice you have much better looking histogram plots inДЄNSWER: Yes, I can help. IDL> pplot(findgen(5),dimension600,450,/buffer) IDL> p.save,idl.eps IDL> p.close. The data seems to be about half a bin out of align with the axisДЄnnotation. Plot, Histogram(data, BINSIZE=1.0), PSYM=10ДЄnd I got this result. But, uh, it doesn't look like the histogram plot I was expecting. QUESTION: I tried drawing a histogram plot by setting the PSYM=10 keyword on the PLOT command.

I forgot to post the code containing the plotting commands as they are right now.

If it isn't too much trouble, could someone explain how to plot a curvefit. There are options to take an average of the data, but I don't know how to use those commands to put a fit on my graphs. My professor that I work with told me about a smooth command, but I haven't been able to find any commands on the harrisgeospatial website that would be relevant to graphing in particular. This shifted previous symbols by two values from their old meanings. Modified to allow PSYM8 and PSYM10 to have their normal meanings. When I tried curve fit, I wasn't able to define a function that the command needs because it's just random data, there's no function I can calculate for the data as a whole. Loosely based on the program MCSYMBOL introduced on the IDL newsgroup 1 September 2006, and MPIPLOTCONFIGDEFINE from the Coyote Library. I was able to get a line of best fit on plot 3 using the command robust_linefit, but I haven't been able to get the command curvefit to plot a curve on my graphs that need a curve fit instead of a line. Six plots of ASCII data on a black background I'm looking to curve fit some data points on a graph using IDL.
