 Author Comment/Response Forum Moderator email me 10/01/02 09:28am Text, Arrows, Circles, etc. are called Graphics Primitives in Mathematica. Most of these are defined when the Kernel is launched. Arrows are defined in one of the Standard AddOn packages. You can load that package: < All] You can add primitives to a plot using Epilog: Plot[x, {x, 0, 1}, Epilog -> {Text["Here is the mid point of the line", {0, 1}], Arrow[{.1, .9}, {.4, .6}], Circle[{.5, .5}, .1], PointSize[.05], Point[{.5, .5}]}, PlotRange -> All] Note the use of PlotRange in each case. In most cases the setting All will suffice. At times, however, you may need to specify the range explicitly. PointSize is an example of a Graphics Directive, that is something that controls the appearance of a Graphics "object." You can also combine a plot and primitives using Show: In[29]:= gr=Plot[x, {x, 0, 1}] In[30]:= Show[{gr, Graphics[{Text["Here is the mid point of the line",{0,1}], Arrow[{.1,.9},{.4,.6}], Circle[{.5,.5},.1],PointSize[.05], Point[{.5,.5}]}]}, PlotRange\[Rule] All] Show, Graphics, Text, Arrow, Circle, etc. are all discused in the documentation available in the Help Browser.
