add a blank part on slot graph

Hello,

I have the following splot graph with color bar :

set term png enhanced font ",15" size 1000,361
set title 'test'
set yr [0:10]
set output 'test.png'
set pm3d
set pm3d map interpolate 10,4
unset key
# jet colormap
set palette defined ( 0 0 0 0.5647, 0.125 0 0.05882 1, 0.25 0 0.5647 1,          \
0.375 0.05882 1 0.9333, 0.5 0.5647 1 0.4392, 0.625 1 0.9333 0, 0.75 1 0.4392 0,          \
0.875 0.9333 0 0, 1 0.498 0 0)
set cbrange [0:1]
set contour base
set cntrparam levels discrete 0
set cntrlabel onecolor
set cntrparam bspline
splot 'test.dat' u 1:2:3 lt 3 lc rgb "#ffffff" lw 2

which gives the graph in attachments.

My values are between 0 and 1 on almost all the graph. For the red square at the bottom center I have very hight values. I want this square in whrite but I want to keep the same color bar from to 0 to 1 with the same color, blue to red, without the whrite and the hight value.

I tried without the values but gnuplot doesn't work with missing values.

I tried to add write for this big values in the colors but I want the color bar from 0 to 1 without write so it doesn't work well.

I tried to add a plot on the graph with :

plot 'blank.dat' u 1:2 w filledcurves

to hide the square but I don't succed to mix plot and splot for the same graph.

I tried the same method with splot :

splot 'blank.dat' u 1:2:(0) w filledcurves

but this doesn't work too, the results are totally wrong.

Can someone help me to have the resultat that I want please ? Thanks.
