Dear List,
My data consist of nine columns and about 50,000 rows. It looks like
this.
-9.0225 3.46464 2.80926 -0.3847 3.73735 1.1058 -2.98936 1.38901 -8.1846
-2.4315 -5.1189 1.8225 3.3798 1.7874 4.693 -3.9286 1.4266 5.7849
-3.4894 -4.0305 3.7879 3.5195 2.9186 2.8685 -6.126 4.978 4.9381
4.5282 3.62558 -3.0455 4.6518 1.39746 0.68652 3.5708 -3.6404 -4.2963
-1.3183 0.6752 -4.0382 -2.5386 -0.6459 1.0689 -0.6392 -6.4141 -4.101
-1.3735 3.1098 -2.8291 -5.2548 -3.3798 1.3959 -1.8605 0.1522 2.1818
-1.0488 0.1071 -3.7154 -1.3748 -5.6218 -0.9989 -2.6763 -4.6548 0.5449
7.948 2.0673 3.8729 8.0537 2.79 -3.6963 8.4584 -1.5122 -6.3354
4.5827 6.1787 -3.1787 1.4554 5.6973 5.3386 10.6077 -0.0424 3.3653
4.1653 8.0266 1.9509 4.2077 5.4182 4.1797 7.9248 1.1502 0.753
3.6046 3.6743 11.8299 9.5704 10.7384 8.675 4.9277 13.6898 13.3279
18.4431 12.3946 22.1126 22.7109 19.4623 17.3565 15.27 17.5922 19.5873
The values in each of the nine columns are almost normally distributed
but have slightly different heights of nine normalised bell shaped
plots.
I was trying to plot each row as a point with error bars. The central
point will be the mean of the nine values in each of rows and the max
and min of the row will be the upper and lower bound of the error
bar. I expect a normally distributed plot with spikes around. Can any
one please help me plotting data in this way ?
Many thanks for any input.
