Owning Class: plots

Requires: MathScript RT Module


errorbar(x, e)

errorbar(x, y, e)

errorbar(x, y, b, a)

errorbar(x, e, attributes)

errorbar(x, y, e, attributes)

errorbar(x, y, b, a, attributes)


Generates a plot with error bars. The error bars represent the uncertainty of the data at each plot point.



Name Description
x Specifies a vector or matrix you want to plot.
y Specifies a vector or matrix you want to plot. size(y) must equal size(x).
e Specifies the lengths of the error bars. The length of each error bar equals 2*e. The length below the plot point and the length above the plot point both equal e. e is a vector or matrix. size(e) must equal size(x).
b Specifies the lengths of the error bars below the plot. b is a vector or matrix. size(b) must equal size(x).
a Specifies the lengths of the error bars above the plot. a is a vector or matrix. size(a) must equal size(x).
attributes Specifies valid plot attributes. Order the plot attributes by color, point style, and line style. For example, 'bo-' specifies that the plot is blue, marks points with circles, and uses solid lines. attributes is a string that accepts a combination of the following values.

'b' Colors the plot blue.
'c' Colors the plot cyan.
'g' Colors the plot green.
'k' Colors the plot black.
'm' Colors the plot magenta.
'r' Colors the plot red.
'w' Colors the plot white.
'y' Colors the plot yellow.
'.' Marks points with dots.
'o' Marks points with circles.
'x' Marks points with crosses.
'+' Marks points with plus signs.
'*' Marks points with asterisks.
'-' Uses solid lines.
':' Uses dotted lines.
'-.' Uses dashed and dotted lines.
'--' Uses dashed lines.
