Suppose I have a set of data,
data= {{0.25, 54, 5, 62}, {0.35, 2878, 354, 3394}, {0.45, 21089, 3824, 27160}, {0.55, 59194, 12313, 79863}};
that I split up into vectors,
a1 = Transpose[data][[1]];
a2 = Transpose[data][[2]];
a3 = Transpose[data][[3]];
a4 = Transpose[data][[4]];
p01data = Select[Transpose[{a1, a2/a4}], #[[2]] > 0 &];
p31data = Select[Transpose[{a1, a3/a4}], #[[2]] > 0 &];
that I want to plot with the command,
Show[
MultipleListPlot[p01data, DisplayFunction->Identity,
SymbolShape->{PlotSymbol[Box,Filled->False]}],
MultipleListPlot[p31data, DisplayFunction->Identity,
SymbolShape->{PlotSymbol[Triangle,Filled->False]}],
PlotRange->All,Frame->True,Axes->False,
DisplayFunction->$DisplayFunction
]
All of this works. I wish to include an estimated Poisson Error, given in column format,
myestimatederror01=Sqrt[a2]/a4;
myestimatederror01=Sqrt[a3]/a4;
I know that the ErrorBar command is used to include this error bar in the style of:
{{x,y},ErrorBar[error]}, but I can't get the command which would do this to a vector to work properly.
I think the following should work, It doesn't - what should I use instead?
p01data = Select[Transpose[{{a1, a2/a4},ErrorBar[Sqrt[a2]/a4] }], #[[2]] > 0 &];
p31data = Select[Transpose[{{a1, a3/a4},ErrorBar[Sqrt[a3]/a4] }], #[[2]] > 0 &];
