Dear Nikolaus I think is NOT such a good idea to transform to a String in order to make a Label for a Plot. In my opinion it can be better to use the HoldForm[] and TraditionalForm[] commands (actually, TraditionalForm[] is not needed in PlotLabel IN MATHEMATICA 6). (*FIRST EXAMPLE: COPY-PASTE AND EVALUATE IN MATHEMATICA 6*) f[x_] := Sin[3 x + Cos[2 x]]; Plot[f[x], {x, 0, 2}, PlotLabel -> HoldForm[f[x]] == f[x]] (*SECOND EXAMPLE: COPY-PASTE AND EVALUATE IN MATHEMATICA 6*) f[x_] :=Exp[x]/x; Plot[f[x], {x, 0, 2}, PlotLabel -> HoldForm[f[x]] == f[x]] (*THIRD EXAMPLE: COPY-PASTE AND EVALUATE IN MATHEMATICA 6*) f[x_] :=Exp[x]/x; TraditionalForm[HoldForm[f[x]]==f[x]] Best regards Jose Mexico -----Mensaje original----- De: Nikolaus Rath [mailto:Nikolaus at rath.org] Enviado el: Martes, 04 de Noviembre de 2008 05:18 Para: mathgroup at smc.vnet.net Asunto: [mg93336] Constructing a Label Hello, I want to automatically construct labels of the form "A = <value of A>" for a number of plots. However, I cannot quite figure out how to generate the above expression. My first idea was to construct it as a string label = "A = " <> ToString[A] but this looks horribly if A is more complicated than just a single literal. So I assume that I have to "concatenate" the Mathematica expressions "A = " and A (rather than the stringified A). But how do I do that? My feeble attempts with label = RowBox["A", "=", A] are displayed exactly the way I entered them, i.e. with the literal "RowBox" printed out. Thanks in advance, -Nikolaus -- =C2=BBIt is not worth an intelligent man's time to be in the majority. By definition, there are already enough people to do that.=C2=AB -J.H.
