Hello:
I have entered data into two lists in Mathematica: centroidEnergy = {1.3485, 1.4780, 1.6176, 1.7820, 1.9123, 2.0274, 2.1635, 2.3163, 2.4213, 2.5191, 2.6515, \ 2.7490, 2.8763, 2.9894, 3.0728, 3.1949, 3.2816, 3.3923, 3.4773, 3.5884, \ 3.6804, 3.7702, 3.8374, 3.9679, 4.0507, 4.1507, 4.2163, 4.3145, 4.4039, \ 4.5056, 4.5089, 4.6440, 4.7331, 4.8497, 4.9290, 5.0019, 5.0862, 5.1815, \ 5.2427, 5.3365, 5.4225, 5.4800} and distanceInAir = {2.0523, 2.0020, 1.9517, 1.8964, 1.8511, 1.8008, 1.7505, 1.7002, 1.6499, 1.5996, 1.5493, 1.4990, 1.4488, 1.3984, 1.3481, 1.2979, 1.2476, 1.1520, 1.0967, 1.0464, 0.99606, 0.95079, 0.89546, 0.84516, 0.79486, 0.74456, 0.69426, 0.64396, 0.59366, 0.54336, 0.49306, 0.44276, 0.39247, 0.34217, 0.29186, 0.24157, 0.19269, 0.14097, 0.090671, 0.040371, 0.000132} I am trying to plot the former vs. the later. The recommended method I have seen to do so is to Transpose the two lists to that M. creates a list of ordered pairs of corresponding items from each one. Then, ListPlot that. However, I can't get the following command to work: it always gives the ensuing error message: dataToPlot = Transpose[{distanceInAir, centroidEnergy}] Transpose :: nmtx :: the first two levels of the onedimensional list {{2.0523, 2.0020, 1.9517, 1.8964, 1.8511, 1.8008, 1.7505, <<28>> , 0.24157, 0.19269, 0.14097, 0.090671, 0.040371, 0.000132}, {<<1>>}} cannot be transposed. ??? Any ideas on how to simply plot centroidEnergy vs. distanceInAir would be greatly appreciated! Thanks.

Well, this thread did not generate any responses after more than 12hrs, so perhaps it was misplaced. In an effort to get it out to a wider audience, I have moved it to college hw help. It has to do with a hw assignment anyway. Sorry for the inconvenience.

the arrays have different lengths,
distanceInAir has 41 elements, and centroidEnergy has 42 elements...
