Hi, oops! Typo on my side. The examples should read: LogLogPlot[x, {x, 10^-3, 10^5}, Ticks -> logtic] LogLogPlot[x, {x, 10^-3, 10^15}, Ticks -> logtic] LogLogPlot[x, {x, 10^-3, 10^35}, Ticks -> logtic] since i named the function logtic :) On side remark: The function is not working well if the min and max values are less thansay a few dex apart, e.g. compare: LogLogPlot[x, {x, 100, 700}, Ticks -> logtic] (* with standard tic function *) LogLogPlot[x, {x, 100, 700}, Ticks -> Automatic] My function reasonably places the subticks, but fails in labeling so you get a plot with nice but meaningless ticks. The standard labeling algorithm is better here, but still fails in placing the sub(sub)ticks. I will try to improve it, but feel free to send me your ideas. On the strange uneven tick lengths: >Looks uneven to me as well, but since the ticks are very small, this >may be a pixel rounding problem. Your ticks seem to be a bit uneven as >well. That's true and this is like it is supposed to be, because I use the exact same tick lengths like the standard LogPlot, This seems to be a rendering problem, not a problem of the Graphics Primitives.
