Yup, it looks like it. > here is the code i am trying out. [Another hint: when posting code, don't wrap it. It won't run as it was posted, and people aren't generally going to be willing to go through and un-wrap the lines in order to try it.] > gnuplot> set title "testing" > gnuplot> set term png > gnuplot> set out "/home/piv/PivData/tmp/images/graph.png" > gnuplot> set xtics (['10/18 09:54', '10/17 22:42', '10/17 11:30', > '10/17 00:18', '10/16 13:06', '10/16 01:54', '10/15 14:42', '10/15 > 03:30', '10/14 16:18', '10/14 05:06', '10/13 17:54', '10/13 06:42', > '10/12 19:30', '10/12 08:18', '10/25 09:54']) OK, You need to get rid of the sqare brackets, and you need an x-position value after each of the strings. > i noticed in the docs for gnuplot, that it can do date/time > and by default uses seconds since 2000. and then you can pass > the format that you want to show it in. would this give the > same kind of result that i am looking for ? It looks like it. Though I've used custom tics in the past, it was never for time values. Based on the help from gnuplot, I suspect you can get what you want without doing custom tics, but rather using the commands set xdata time set timefmt set format x Interestingly, using Unix timestamps creates some sort of resolution problems. The following ought to work but doesn't. It appears that there is some sort of resolution problem: ------------------------------8<------------------------------ import Gnuplot,time,sys,math def pause(): sys.stdout.write("Press enter to continue: ") sys.stdin.readline() def fgrid(start,stop,count): for i in xrange(count): yield start + ((stop-start)*i)/count start = time.time() xdata = [x for x in fgrid(0,600.0,10)] # two minutes worth ydata = [math.sin(x/100.0) for x in xdata] data = Gnuplot.Data(xdata,ydata,with='linespoints',using=(1,2)) gp = Gnuplot.Gnuplot(debug=1) gp.title('Data starting at %s' % time.asctime(time.gmtime(start+xdata[0]))) # x axis will use default tics (seconds since start of run) gp.plot(data) pause() # same data with x value as Unix timestamps xdata = [x+start for x in xdata] print xdata data = Gnuplot.Data(xdata,ydata,with='linespoints',using=(1,2)) gp('set xdata time') gp('set timefmt "%s') gp('set format x "%r"') gp('set xtics 120') gp.plot(data) pause() ------------------------------8<------------------------------ -- Grant Edwards grante Yow!
