Re: [Gnuplot-info] simple row/col plot: 1st row to xtics & autocolumn

[theozh <th...@gm...>]

ok... you can get get the number of columns via stats $Data and STATS_columns.
The following code does what I intended to do.
(as long as there is only one headerline...)


### gnuplot code
reset session

$Data <<EOD
xxxx	ColA	ColB	ColC	ColD
Row1	1.10	1.20	1.30	1.40
Row2	2.10	2.20	2.30	2.40
Row3	3.10	3.20	3.30	3.40
Row4	4.10	4.20	4.30	4.40
EOD

stats $Data u 0 nooutput
ColCount = STATS_columns
RowCount = STATS_records
 
set xrange[-0.5:ColCount-1.5]
set yrange[-0.5:RowCount-1.5]
plot for [j=2:ColCount] \
    $Data using (j-2) \
    : ($0-1) \
    : (column(j)/10.) \
    : ytic(1) \
    : xtic(columnhead(j)) with circles notitle,\
    for [j=2:ColCount] \
    $Data using (j-2):($0-1):(stringcolumn(j)) with labels notitle

### end code
