no GPVAL_ variable for logscale

[Anglès d'Auriac]

Hello
is there a way to know inside a script called by the command call if x and y are logscale. I did not find any GPVAL reflecting this state ?
thank you

The full set of GPVAL variables is updated at the end of each "plot" command. If you have not yet issued a plot command, any variables that have to do with the plot are not yet present.
So

gnuplot > show var GPVAL_Y

       Variables beginning with GPVAL_Y:

gnuplot> plot x
gnuplot> show var GPVAL_Y

        Variables beginning with GPVAL_Y:
        GPVAL_Y_MIN = -10.0
        GPVAL_Y_MAX = 10.0
        GPVAL_Y_LOG = 10.0
        GPVAL_Y2_MIN = -10.0
        GPVAL_Y2_MAX = 10.0
        GPVAL_Y2_LOG = 10.0

But it is true that there is not a value that simply says "logscale is active on this axis".

Ok Thank you very much.
I was comparing the GPVAL variables before and after set logs but without replot-ing.
