Although the MultipleListPlot package has some nice functions in it like
Symbol and MakeSymbol, I always find the standard paradigm difficult to use.
It is often easier to deal directly with graphics primitives.
Here is an example.
Needs["Graphics`MultipleListPlot`"]
Needs["Graphics`Colors`"]
This makes some sample data...
data =
Module[{y},
Table[{{x, y = x + 0.5 + 5Random[Real, {-0.1, 0.1}]},
ErrorBar[3{-Random[Real, {0.3, 1}], Random[Real, {0.3, 1}]}]}, {x,
1, 15}]];
data
Length[data]
MultipleListPlot[data];
The way to put a style into the error bars should be to use the
ErrorBarFunction option. But, although the example in the Help works, I
could not make an ErrorBarFunction that worked for this case. (After
spending an hour or so.) Perhaps I am making a silly error and someone will
point out how to do it, but in the meantime I suspect there is a bug in the
ErrorBarFunction.
myerrorbar[p_, ErrorBar[{yminus_, yplus_}]] :=
Module[{x, y},
{x, y} = p;
{Red, Line[{{x, y + yminus}, {x, y + yplus}}]}]
MultipleListPlot[data, ErrorBarFunction -> myerrorbar];
does not work and gives multiple errors.
So I fell back on using simple graphics primitives.
data2 = data /. {p_, ErrorBar[{yminus_, yplus_}]} :>
Module[{x, y},
{x, y} = p;
{Point[p], {Red, Line[{{x, y + yminus}, {x, y + yplus}}]}}];
Show[Graphics[
{AbsolutePointSize[4],
data2}],
Frame -> True,
PlotLabel -> "Error Bars with Style",
ImageSize -> 450];
I made simple red lines for the error bars, but one could make them as fancy
as one wants.

For the axes labels you can use StyleForm or Default font comands. For the
thickness and color of error bars I also have the same question!

I am having trouble figuring out how to change the color and thickness of
ErrorBars. Can anyone help me with this problem? ALso, how do you change
the font and font size of an AxesLabel?
Thank you much for any suggestions.
