Make Y-axis ticks visible in LogPlot (V12)?

Psi Meson

Posted 6 years ago

Why the y-axis ticks are almost invisible (light grey in color) when a graph is saved as svg in both Mathematica 11.3 and 12 (I use ubuntu 18.04): LogPlot[Exp[-t], {t, 0.0, 2.0}, PlotRange -> {{0.0, 1.5}, {0.01, 10^0}}, Frame -> True, FrameStyle -> Directive[Black, Thick], FrameTicksStyle -> Directive[Black, FontOpacity -> 1, 20], PlotStyle -> {Black, Thickness[0.005]}, AspectRatio -> 1/GoldenRatio]

A simple way to diminish that problem is to use `GridLines`. With that option IMHO graphics become more appealing anyway! LogPlot[Exp[-t], {t, 0.0, 2.0}, PlotRange -> {{0.0, 1.5}, {0.01, 10^0}}, Frame -> True, FrameStyle -> Directive[Black, Thick], FrameTicksStyle -> Directive[Black, FontOpacity -> 1, 20], PlotStyle -> {Black, Thickness[0.005]}, AspectRatio -> 1/GoldenRatio, GridLines -> {Automatic, Flatten[Range[10] # & /@ {.01, .1, 1}]}]

Hi Neil, Thanks for taking a look at it. I think I have no other options than to use the workaround you suggested.

I forwarded this thread to support. They confirmed the bug and forwarded it to the developers. Did my workaround help you? Regards, Neil

There is a workaround but you must then specify everything about your ticks. ticksv[min_, max_] := Table[{i, Style[i, 12], {.02, 0}, Thick}, {i, 0, max, 0.2}] ticksh[min_, max_] := Table[{i, Style[i, 12], {.02, 0}, Directive[Red, Thick]}, {i, 0.5, max, 0.5}] LogPlot[Exp[-t], {t, 0.0, 2.0}, Ticks -> {ticksh, ticksv}] to get Regards, Neil

It looks like a bug in `LogPlot`. `Thickness` has effect only on the ticks on the bottom of the frame: LogPlot[Exp[-t], {t, 0.0, 2.0}, Frame -> True, FrameTicksStyle -> {{Directive[Black, Thickness[0.01`]], Directive[Blue, Thickness[0.01`]]}, {Directive[Red, Thickness[0.01`]], Directive[Green, Thickness[0.01`]]}}]

It looks like a bug in LogPlot. Thickness has effect only on the ticks on the bottom of the frame:

LogPlot[Exp[-t], {t, 0.0, 2.0}, Frame -> True,
 FrameTicksStyle ->
  {{Directive[Black, Thickness[0.01`]],
    Directive[Blue, Thickness[0.01`]]},
   {Directive[Red, Thickness[0.01`]],
    Directive[Green, Thickness[0.01`]]}}]

Is there a way to get around it?
