print cvs with decription column and multiple rows - gnuplot

Question

i've got a csv file with this content (Row = Title + 10 Values, Row = Line in chart)
column-count is known (but would be great if only the Title is needed and value count is open (but same for all rows)), row count is open
Test1;0,051;0,040;0,051;0,052;0,051;0,049;0,051;0,052;0,059;0,044
Test2;0,016;0,016;0,016;0,019;0,021;0,021;0,021;0,021;0,022;0,022
Test3;0,216;0,200;0,210;0,205;0,205;0,205;0,203;0,206;0,205;0,204
result in LibreOffice
now i want to print it with gnuplot
i tried it with
set xrange [1:10]
set yrange [0:2]
plot for [row=0:*] 'test.csv' matrix every :::row::row with lines
but that only gives me several error messages
"gnuplot.txt" line 7: warning: matrix contains missing or undefined values
"gnuplot.txt" line 7: warning: matrix contains missing or undefined values
"gnuplot.txt" line 7: warning: matrix contains missing or undefined values
"gnuplot.txt" line 7: warning: matrix contains missing or undefined values
would be nice if someone can give me a hint

Answer 1

Unfortunately, gnuplot doesn't like data in rows and doesn't have a transpose function. I guess there is a way to plot rows with matrix as you tried, but currently I don't see a direct way to include the rowheaders as key entry.
So, either you use an external tool and transpose your data or you use the cumbersome gnuplot-transpose-attempt below and then plot columns. At least, this should work for Linux as well as for Windows without the installation of extra tools.
Your decimal sign is ,. Since my standard decimalsign is ., I had to set:
set decimalsign locale 'french' # or 'german' might also work
Data: test.csv
Test1;0,051;0,040;0,051;0,052;0,051;0,049;0,051;0,052;0,059;0,044
Test2;0,016;0,016;0,016;0,019;0,021;0,021;0,021;0,021;0,022;0,022
Test3;0,216;0,200;0,210;0,205;0,205;0,205;0,203;0,206;0,205;0,204
Code:
### plot row data with rowheader as key entry
reset session
myFile = 'test.csv'
set datafile separator ';'
set decimalsign locale 'french' # or 'german' should also work
# transpose data
stats myFile u 0 nooutput
set table $Dummy
set print $DataTransposed
do for [i=1:STATS_columns] {
LINE = ''
do for [j=0:STATS_records-1] {
plot myFile u (a=stringcolumn(i)) every ::j::j with table
LINE = LINE.sprintf('%s', j < STATS_records-1 ? a.";" : a)
}
print LINE
}
set print
unset table
undefine $Dummy
plot for [i=1:STATS_records] $DataTransposed u ($0+1):i w l ti columnheader
### end of code
Result:
