Interval graph plotting in gnuplot -


i have equation goes this

f(x) = x*10 ; 0 < x <= 10      = x*x + x*10 ; 10 < x < 20

how plot f(x) in 1 graph using gnuplot?

plot [0:20] x <= 10 ? x*10 : x*x + x*10

update: if have more 2 functions, can use approach:

f(x) = x <= 10 ? x \      : x <= 20 ? x**2 \      : x <= 40 ? sqrt(x) \      : x**3

and afterwards,

plot [0:40] f(x)

to clarify, value f(x) be:

  • x if x equal or less 10
  • x^2 if x greater 10 , equal or less 20
  • square root of x if x greater 20 , equal or less 40
  • x^3 if x greater 40

i'm using abcpdf , i'm curious if can recursively call addimageurl() function assemble pdf document compile multiple urls? something like: int pagecount = 0; int theid = thedoc.addimageurl("http://stackoverflow.com/search?q=abcpdf+footer+page+x+out+of+", true, 0, true); //assemble document while (thedoc.chainable(theid)) { thedoc.page = thedoc.addpage(); theid = thedoc.addimagetochain(theid); } pagecount = thedoc.pagecount; console.writeline("1 document page count:" + pagecount); //flatten document (int = 1; <= pagecount; i++) { thedoc.pagenumber = i; thedoc.flatten(); } //now try again theid = thedoc.addimageurl("http://stackoverflow.com/questions/1980890/pdf-report-generation", true, 0, true); //assemble document while (thedoc.chainable(theid)) { thedoc.page = thedoc.addpage(); theid = thedoc.addimagetoc
