I'm trying to create a BarChart on which images are the labels of each bar.

A Minimal example of what I'm trying to do:

image1 = Import["test1.png"];
image2 = Import["test2.png"];
image3 = Import["test3.png"];
BarChart[{0.4, 0.2, 0.8}, ChartLabels -> {image1, image2, image3}]

The problem is the position of the image on the label. The image is not resized to fit within the Bar width, and so it fills a great part of the plot.

Another problem is that the image is not centered: the bottom left corner of it is on the label's expected position, and not the center of it.

Any ideas how I can solve this?


as example of an image, wikipedia's picture of the day:


works for the problem in hands. (Thanks J.M. for pointing out)

I don't know if this is satisfying but you can always manually resize:

BarChart[{0.4, 0.2, 0.8},
 ChartLabels ->
  (Image[#, ImageSize -> 40] & /@
    {image1, image2, image3})

enter image description here

  • $\begingroup$ strangely, the code you presented in my machine/version (Mac OS 10.6, mathematica 9) does not give the result you show. It shows the problem I was trying to solve, namely the image is not centered on the Label's "place holder", but the bottom left corner of it is. $\endgroup$ Apr 18, 2013 at 10:06

  • $\begingroup$ @J.C.Leitão: does BarChart[{0.4, 0.2, 0.8}, ChartLabels -> Placed[(Image[#, ImageSize -> 40] & /@ {image1, image2, image3}), Below]] work? (you can play around with Placed to get other alignments) $\endgroup$ Apr 18, 2013 at 10:46
  • $\begingroup$ @PinguinDirk: I played around, and so far only the answer below works. However, the positions are relative, which really screw the exporting feature. $\endgroup$ Apr 18, 2013 at 14:03

    $\begingroup$ @J.C.Leitão: well, I see that @cormullion posted just such answer. Below seems fine to me (Mac too) - didn't try to export though. $\endgroup$ Apr 18, 2013 at 15:12

Mr.Wizard's solution doesn't quite work for me on MacOSX/Mathematica9, but a slight tweak of his magic spell works:

BarChart[{0.4, 0.2, 0.8}, 
 ChartLabels -> Placed[{image1, image2, image3}, 
   {{0, 0}, {-0.5, 1}}, 
   (Image[#, ImageSize -> 50] &)]]


  • $\begingroup$ Notice that -0.5 is arbitrary, and needs tweaking depending on the image size. $\endgroup$ Apr 18, 2013 at 12:09
