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}}]}]]

    $\begingroup$ +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

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

    $\begingroup$ 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]

enter image description here

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]
