Here is an example using some random data with random errors: chartData = MapThread[{#1 -> #2} &, {RandomReal[1, 10], RandomReal[0.1, 10]}] and some random labels: labels = ToString /@ RandomReal[100000, 10] Now plotting it, as per the tutorial: BarChart[chartData, ChartElementFunction -> errorBar["Rectangle"], ChartLabels -> Placed[labels, Axis, Rotate[#, Pi/2] &]] The labels are: {"99539.6", "17862.9", "14683.4", "32667.2", "42690.", "70230.8", "59050.4", "59204.7", "9138.2", "19080.3"} However, in the plot: The first label is repeated incorrectly for all the bars, what's going on here? Without error bars the labels on the plot are correct: BarChart[RandomReal[1, 10], ChartLabels -> Placed[labels, Axis, Rotate[#, Pi/2] &]] graphics plotting share|improve this question edited Mar 17 at 15:38 István Zachar 28.7k1493220 asked Mar 6 '12 at 22:10 s0rce 6,06122465 add a comment| 1 Answer 1 active oldest votes up vote 7 down vote accepted In the original code, chartData is of the form {{value1 -> error1}, {value2 -> error2}, ... }, but it should be of the form {value1 -> error1, value2 -> error2, ... }. To get the right labels you could do something like (note the missing brackets in chartData) chartData = MapThread[#1 -> #2 &, {RandomReal[1, 10], RandomReal[0.1, 10]}]; BarChart[chartData, ChartElementFunction -> errorBar["Rectangle"], ChartLab
