# Plot three vertical axes

I am trying to make a plot with 3 vertical axes (frame with three labels). The desired plot done in other software is as follow.

Here is my code for Mathematica.

    dAta = Table[{i, RandomReal[{1, 5}], 20, RandomReal[{50, 80}]}, {i,
100}];
tEstPt1 =
ListPlot[#, ImageSize -> 400, Frame -> {{True, False}, {True, True}},
FrameTicks -> {{True, None}, {True, True}}(*All*),
PlotRange -> {{0, 100}, {0, 6.0}}, Joined -> True,
PlotStyle -> Blue, ImagePadding -> {{60, 65}, {60, 10}},
Axes -> False,
FrameStyle -> {{Directive[Black, AbsoluteThickness[0.75], 12] ,
Directive[Black, AbsoluteThickness[0.75], 12]}, {Directive[
Black, AbsoluteThickness[0.75], 12] ,
Directive[Black, AbsoluteThickness[0.75], 12]}},
FrameTicksStyle -> {{Directive[Black, Bold, 12,
AbsoluteThickness[0.75]],
Directive[Black, Bold, 12,
AbsoluteThickness[0.75]]}, {Directive[Black, Bold, 12,
AbsoluteThickness[0.75]],
Directive[Black, Bold, 12, AbsoluteThickness[0.75]]}},
FrameLabel -> {{Style[#, Black, Bold, 14] &@("Y-label"),
None}, {Style[#, Black, Bold, 14] &@("X-label"),
None}} ] &@(dAta[[1 ;; 100, {1, 2}]])
tEstPt2 =
ListPlot[#, ImageSize -> 400,
Frame -> {{False, True}, {False, False}},
FrameTicks -> {{False, All}, {False, False}}(*All*),
PlotRange -> {{0, 100}, {0, 40.0}}, Joined -> True,
PlotStyle -> Green, ImagePadding -> {{60, 65}, {60, 10}},
Axes -> False,
FrameStyle -> {{Directive[Black, AbsoluteThickness[0.75], 12] ,
Directive[Black, AbsoluteThickness[0.75], 12]}, {Directive[
Black, AbsoluteThickness[0.75], 12] ,
Directive[Black, AbsoluteThickness[0.75], 12]}},
FrameTicksStyle -> {{Directive[Black, Bold, 12,
AbsoluteThickness[0.75]],
Directive[Black, Bold, 12,
AbsoluteThickness[0.75]]}, {Directive[Black, Bold, 12,
AbsoluteThickness[0.75]],
Directive[Black, Bold, 12, AbsoluteThickness[0.75]]}},
FrameLabel -> {{None,
Style[#, Black, Bold, 14] &@("Y1-label")}, {None,
None}} ] &@(dAta[[1 ;; 100, {1, 3}]])
tEstPt3 =
ListPlot[#, ImageSize -> 400,
Frame -> {{False, True}, {False, False}},
FrameTicks -> {{False, All}, {False, False}}(*All*),
PlotRange -> {{0, 100}, {20, 90.0}}, Joined -> True,
PlotStyle -> Red, ImagePadding -> {{60, 65}, {60, 10}},
PlotRangePadding -> {{0, 20}, {0, 0}}, Axes -> False,
FrameStyle -> {{Directive[Black, AbsoluteThickness[0.75], 12] ,
Directive[Black, AbsoluteThickness[0.75], 12]}, {Directive[
Black, AbsoluteThickness[0.75], 12] ,
Directive[Black, AbsoluteThickness[0.75], 12]}},
FrameTicksStyle -> {{Directive[Black, Bold, 12,
AbsoluteThickness[0.75]],
Directive[Black, Bold, 12,
AbsoluteThickness[0.75]]}, {Directive[Black, Bold, 12,
AbsoluteThickness[0.75]],
Directive[Black, Bold, 12, AbsoluteThickness[0.75]]}},
FrameLabel -> {{None,
Style[#, Black, Bold, 14] &@("Y2-label")}, {None,
None}} ] &@(dAta[[1 ;; 100, {1, 4}]])
Overlay[{tEstPt1, tEstPt2, tEstPt3}]


The axes on the right are overlapping instead of offsetting. The main problem is offsetting the axes.
