Is there anyone who know how to make diagonal lines inside the chart bar like the below picture?
There has to be a better way than this:
BarChart[{1, 2, 3, 4, 5, 6},
ChartElements ->
Graphics[{Blue, Thick, Line[{{0, 0}, {0.5, 0.05}}]}]]

2$\begingroup$ +1 But (@Kim) please read Tufte on Moire patterns and chartjunk. Kudos to WRI for making this kind of stuff hard to construct. $\endgroup$ – whuber Mar 14 '13 at 17:27

1$\begingroup$ @whuber, yes you're right, I forgot myself. I feel guilty now... :) $\endgroup$ – cormullion Mar 14 '13 at 17:52

3$\begingroup$ Your illustration is a beautiful example of what Tufte writes about: the space between bars really does seem to vibrate, even more so on the screen than on the printed page. Quite distracting and very useful if your objective is to draw attention away from the data. :-) $\endgroup$ – whuber Mar 14 '13 at 18:43
With apologies to @whuber and Tufte :)
You can also do the following using Texture
and System`BarFunctionDump`TextureBar
as ChartElementFunction
.
First, using the function hatchF
from this answer
ClearAll[hatchF]
hatchF[mf_List: {# &, #2 &}, mesh_List: {50, 50},
style_: GrayLevel[.5], opts : OptionsPattern[]] :=
ParametricPlot[{x, y}, {x, 0, 1}, {y, 0, 1}, Mesh -> mesh,
MeshFunctions -> mf, MeshStyle -> style, BoundaryStyle -> None,
opts, Frame -> False, PlotRangePadding -> 0, ImagePadding -> 0, Axes -> False]
to create hatched images
t1 = hatchF[{# - #2 &}, {20}, White, MeshShading -> {Blue, White}];
t2 = hatchF[{# - #2 &, #2 + # &}, {20}, Gray, PlotStyle -> None,
MeshShading -> {{Blue, White}, {Red, Yellow}}];
And a few Texture
examples from ExampleData
:
t3 = ExampleData[{"ColorTexture", "Metal4"}];
t4 = ExampleData[{"ColorTexture", "WhiteMarble"}];
t5 = ExampleData[{"ColorTexture", "Kingwood"}];
Then, Texture
these images and use them as the setting for PlotStyle
together with System`BarFunctionDump`TextureBar
for the option ChartElementFunction
:
BarChart[{3, 2, 3, 4, 3},
ChartStyle -> (Texture /@ {t1, t2, t3, t4, t5}),
ChartElementFunction -> System`BarFunctionDump`TextureBar]
You can go further along this slope:
RectangleChart[Tuples[{1, 4, 3}, 2],
ChartStyle -> (Texture[ImageMultiply[ExampleData[{"TestImage", "Mandrill"}], #]] & /@
ColorData[30, "ColorList"]),
ChartElementFunction -> System`BarFunctionDump`TextureBar]
