More space between the ordinate axis ans plot labels

Question

I have this graphics. All I want is more place like a space or interval between labels and the ordinate azis. How could I do that?

Manipulate[
 Plot[{E^(-k t) , E^(-k t) (-1 + E^(k t)) + 0.1}, {t, 0, 10}, 
  PlotStyle -> {Red, Blue}, 
  PlotLabels -> {Style["u[t]", 16], Style["x(t)", 16]}, 
  AxesLabel -> {Style["t", Bold, 16], Style["x(t),u(t)", Bold, 16]}, 
  TicksStyle -> {{FontSize -> 16}, {FontSize -> 16}}], {k, 0, 2}]

Thanks!

Answer 1

Notice how much simpler the code can be if you were use the BaseStyle option to set the font size. Also, notice that the code below does not show the spacing problem you are experience. I am running V11.3.0 on MacOS 10.13.4 (High Sierra).

Manipulate[
  Plot[{E^(-k t), E^(-k t) (-1 + E^(k t)) + 0.1}, {t, 0, 10},
    BaseStyle -> {FontSize -> 16},
    PlotStyle -> {Red, Blue},
    PlotLabels -> {"u[t]", "x(t)"},
    AxesLabel -> {"t", "x(t), u(t)"}],
  {k, 0, 2, .1, Appearance -> "Labeled"}]

You can wrap your label inside Pane and specify FrameMargins for it.

Manipulate[
 Plot[
  {E^(-k t), E^(-k t) (-1 + E^(k t)) + 0.1}, {t, 0, 10}
  , PlotStyle -> {Red, Blue}
  , PlotLabels -> {Style["u[t]", 16], Style["x(t)", 16]}
  , AxesLabel -> {Style["t", Bold, 16], 
    Pane[Style["x(t),u(t)", Bold, 16], 
     FrameMargins -> {{0, 0}, {20, 0}}]}
  , TicksStyle -> {{FontSize -> 16}, {FontSize -> 16}}
  ]
 , {k, 0, 2}
 ]
