Labels

Controlling the aspect of labels

Every plot in ctioga normally contains 3 labels, a title and a label for each of the axes. These can be set using the -t, -x and -y options:

ctioga --xpdf --math 'x**2' '1 - x**2' '30 * cos(x)' \
    -t 'A plot with nice labels' \
    -x 'A nice $x$ label' \
    -y 'A very nice $y$ label'

ctioga gives you a fairly good control on label position, size, angle, color:

ctioga --xpdf -N --math 'x**2 - 30' '30 - x**2' '30 * cos(x)' \
    --scale title 2.3 \
    -t 'A plot with nice labels' \
    --angle xlabel -15 \
    --scale xlabel 1.5 --shift xlabel 1.3 \
    -x 'A nice $x$ label' \
    --lcolor ylabel BrickRed \
    --side ylabel RIGHT \
    -y 'A very nice $y$ label'

Version 1.7: These settings now apply to tick labels as well:

ctioga --xpdf -N --math 'x**2 - 30' '30 - x**2' '30 * cos(x)' \
    -t 'Tick labels can be tweaked as well' \
    --scale yticks 1.5 --angle yticks -15 \
    --shift xticks 1.5 --angle xticks -90

Note however that the --lcolor setting does not apply (it is a Tioga limitation, at least for now).
