# Increasing the size of fonts and tick marks and numbers in a contour plot [closed]

Mathematica 8.0

I have some function of two variables, $x$ and $y$, and I would like to plot $x$ vs. $y$ parameter space probability distribution function in which the contours are represented by Rainbow ColorDatafunction of ContourPlot command. I managed to create the contour plot that include the labels of the axes, tick marks and a bar legend next to the main plot in the following manner:

mainPlot =
ContourPlot[
FractionalCoverageHybridlog[s, M], {s, 20.3, 22.3}, {M, 9, 13},
Contours -> {-8.1, -8.15, -8.2, -8.25, -8.3, -8.35, -8.4, -8.45, \
-8.5, -8.6, -8.7, -8.8, -8.9, -9, -9.1, -9.2, -9.3, -9.4, -9.5, -10},
ColorFunctionScaling -> False,
ColorFunction -> (ColorData["Rainbow"][Rescale[#, {-10, -8.1}]] &),
PlotRange -> {{20.3, 22.3}, {9, 13}, {-10, -8.1}},
ImageSize -> 400,
PlotLabel -> "X vs. Y",
FrameLabel -> {"x-coordinate","y-coordinate"}];

legendPlot =
ContourPlot[y, {x, -10, 0.1}, {y, -10, -8.1},
Contours -> {-8.1, -8.15, -8.2, -8.25, -8.3, -8.35, -8.4, -8.45, \
-8.5, -8.6, -8.7, -8.8, -8.9, -9, -9.1, -9.2, -9.3, -9.4, -9.5, -10},
ColorFunctionScaling -> False,
ColorFunction -> (ColorData["Rainbow"][Rescale[#, {-10, -8.1}]] &),
AspectRatio -> 10,
PlotRange -> {{-10, 0.1}, {-10, -8.1}, {-10, -8.1}},
FrameTicks -> {None, {-8.1, -8.15, -8.2, -8.25, -8.3, -8.35, -8.4, \
-8.45, -8.5, -8.6, -8.7, -8.8, -8.9, -9, -9.1, -9.2, -9.3, -9.4, \
-9.5, -10}, None, None}, ImageSize -> 100];

Show[Graphics[Inset[mainPlot, {Left, Bottom}, {Left, Bottom}]],
Graphics[Inset[
legendPlot, {25, 9.5}, {Left, Bottom}, {1, Automatic}]],
PlotRange -> {{20.3, 26}, {9, 13}}, ImageSize -> 500]


However, as I am trying to convert this plot into a pdf and use it for my latex file, it seems that axes labels and tick marks and the bar legend numbers are all very small and cannot really be read easily. Could you please teach me how to do this more efficiently?

Sincerely,

FrameLabel -> {Style["x-coordinate", 24],Style["y-coordinate", 24]}

FrameTicksStyle -> Directive[FontSize -> 22]
