You are applying your function to the list of automatic labels. That list is of the form {{x1, y1, label1}, {x2, y2, label2}, ...} Your function converts each of them to Text[label, {x, y}]; this is the same as would occur if you used ContourLabels -> Automatic Bob Hanlon ---- mr.pajenn at gmail.com wrote: > Here's the example of a ContourPlot: > > {i = 0, j = 0}; > > ContourPlot[{x == 4 + y/4, y == 2 + x/2}, {x, 0, 10}, {y, 0, 10}, > ContourLabels -> (Text[#3, {val1[i += 1] = #1, val2[j += 1] = #2}] > &)] > > Print[{val1[1], val2[1], val1[2], val2[2]}] > > The output is a basic plot with two lines, and I've set it to record > and print the values of #1 and #2 arguments, which are: > val1[1] = 6.4857 > val2[1] = 9.9429 > val1[2] = 0.095238 > val2[2] = 2.0476 > > I'd like to know where those values came from so that I can apply the > #1 and #2 arguments intelligibly. > > Thanks in advance. > >
