Hello

The following is a sample code that I tried in maple 10 standard.

My problem is that whenever a plot contains a function with negative values, a usual plot displays it as it should, but when i try to display it on a log scale, all i get is an empty plot

sample code:

f:x=-5;
plot(f(x), x = -10 .. 10, y = -10 .. 10, axis = [mode = log]);

this gives out an empty plot, with axis in range of 10^0 to 10^(-6) on both axes - maple seems to ignore the instruction to display negative values.

perhaps it would also be helpful if someone could point out how to turn these values into decimals.

thanks in advance.
