The columns are accumulative.
What I'd like to have is have it proportional, for example in row 2.
10 - 8 = 2,
8 - 6 = 2,
6 - 4 = 2,
4 - 2 = 2,
2 - 1 = 1
If you want to plot the difference between two columns, then you must calculate the difference inside the using statement like
plot "tmp.data" using ($2 - $3):xtic(1)
to plot the difference between third and second column. For all your columns, and keeping the second as is, use (using the inline data $data requires 5.0):

I have data file:

0 0 3 -0.41 6 0.50

I want to plot the figure like this which connects each point in the lines. Can you tell me how?
The following suggestion uses the plotting styles with boxxyerror, with vectors and with labels.
The zero level gets the color of the last entry because everything is plotted on top of each other. Check the following example as starting point for further tweaking.

Addition:
From your comments: If the levels are to close such that the labels overlap, you could add an individual offset (here in column 8).
Check the following example where the data is modified that the levels B and E are very close.
Script:
Edit after OP's comment: simplifications, with xerrorbar instead of with boxxyerror and with custom xtics
Edit 2: simplified input data
reduce the input data to the minimum
add xticlabel from columnheader
use column number as x-coordinate. Mind the difference in ...$Data u (col):col:...: e.g. if col=1, (col) is the fixed value of 1, and col is the value from column 1.

using Gnuplot to plot 3D charts with splot and errors with zerror does not allow us to have different lines with points. Here are examples. I would like to use splot with error bars and still differentiate lines by different points. Like it is mentioned here:
The operation of with is also the same as in plot, except that the
plotting styles available to splot are limited to lines, points,
linespoints, dots, and impulses; the error-bar capabilities of plot
are not available for splot.
Is there another solution for this problem in Gnuplot?
As you note, there doesn't seem to be a direct plotting style for drawing error bars in 3D. It is possible to manipulate the input data to pseudo-draw the error bars with lines style.
Sample Script:
$inputdata <<EOD
# x y z zlow zhigh
1 1 1 0 2
2 1 2 1 3
3 1 3 2 4

It uses the line-wise data (x,y,z,zlow,zhigh) of the data points and error range as inputs to build the data to draw the error bars and whiskers. Once that's done, we can draw each part of the error bar in lines style.
Result:
Here's another solution using vector style which is actually much simpler than above script.
Sample script:
$inputdata <<EOD
# x y z zlow zhigh
1 1 1 0 2

Thanks.
First a remark for the readers: hypertext works only with the 4.7 development version.
To your problem: For plotting the labels, you must also use the same x and y columns 1 and 2 (you use 0 and 1). And you need the third column for the labels and a fourth one for the ps var. So your plot part for the labels is:
plot for [i=0:int(STATS_max)-1] filename \
using (rand_x(timecolumn(1))):(i < $4 ? rand_y($2) : 1/0):3 pointtype 7 linecolor palette notitle,\
'' u 1:2:3:3 with labels hypertext point pt 7 ps var lc rgb "#ffee99"
I have the below data file which has:
1st column is the layer number.
2nd column is the X axis.
3rd column is the Y axis.
1 1999-01-19 21 0 1
1 2009-07-01 0 1 1
1 2008-08-20 2 1 1
1 2008-12-18 1 1 1
2 2004-05-12 4 1 1
2 2009-07-29 2 1 1
3 2008-08-07 0 1 1
4 2006-03-08 1 1 1
4 2004-08-31 9 1 1
4 2001-03-27 12 1 1
My questions:
1. How can I plot the above data file in 3D knowing that each layer must have different Z offset and different color?
the below must be plotted with Z=1
1 1999-01-19 21 0 1
1 2009-07-01 0 1 1
1 2008-08-20 2 1 1
1 2008-12-18 1 1 1
and the below with Z=2
2 2004-05-12 4 1 1
2 2009-07-29 2 1 1
and so on.
2.If I want to select the layer number 2, other layers must be shaded with gray and this layer must be colored with red for example, is that possible? so it's like highlighting the selected layer.
thx.
To plot the points just use
set xdata time
set timefmt '%Y-%m-%d'
set format x '%Y'
splot 'data.dat' using 2:3:1
That uses the layer number as z-value. To get something else, just specify a function for the z-value depending on the layer number:
zpos(z) = 1 + 0.5*z
splot 'data.dat' using 2:3:(zpos($1))
For the coloring use linecolor rgb variable. That allows you to specify the color in the last column. This color must be the integer representation of an rgb-tuple which is 65536*red + 256*green + blue, with red, green and blue being in the range [0:255].
The following script plots the points in layer 2 in dark red:
set xdata time
set timefmt '%Y-%m-%d'
set format x '%Y'
rgb(r,g,b) = 65536*r + 256*g + b
gray = rgb(200,200,200)
red = rgb(200,0,0)
layer = 2
set view 66,20
splot 'data.dat' using 2:3:1:($1 == layer ? red : gray) with points pt 7 linecolor rgb variable notitle
The result with 4.6.4 is:
