serrorbars( x, y, errorVals, lineStyle) | |
serrorbars( x, y, errorVals, lineStyle, lineType, lineWidth, lineColor, symbolName) | |

If present, the argument lineStyle must be a character
row vector with the value "scatter"
, "line & scatter"
,
or "regression"
and specifies the type of line plot to create.
If present, the argument lineType is a character row
vector which specifies the type of line to use for the current
plot if the current plot includes lines. Valid values are:
"None"
, "Solid"
, "Long dash"
, "Medium dash"
,
"Short dash"
, "Dotted"
, "Dash-dot"
,
and "Dash-dot-dot"
.
If present, the argument lineWidth specifies the width
of lines in the current plot in inches. The value of
lineWidth must range between 0.0 and 0.25.
If present, the argument lineColor is a character row
vector which specifies the color for lines in the current plot.
Valid values are:
"black"
, "blue"
, "cyan"
,
"dkblue"
, "dkcyan"
,
"dkgray"
, "dkgreen"
, "dkpink"
,
"dkred"
, "dkyellow"
, "gray"
,
"green"
, "pink"
, "red"
, "white"
,
and "yellow"
.
If present, the argument symbolName is a character row
vector which specifies the name of the symbol to use in the current plot.
Valid values are:
"none"
, "circle"
, "square"
, "upward triangle"
, "downward triangle"
,
"diamond"
, "hexagon"
, "horizontal bar"
, and "vertical bar"
.
Examples
clear
x = 1:1:10
y = x^2
errorVals = rand(rowdim(x), 1) * 10
serrorbars(x, y, errorVals)
SigmaPlot will create the following error bars plot
If you continue the example above by entering
serrorbars(x, y, errorVals, "regression")
SigmaPlot will create another graph of the data that includes a
regression fit line through the x,y data
Multiple Y vectors with Multiple Error Vectors
serrorbars
command can also be used to plot multiple
Y vectors. If you continue the example
above by entering
y = [y, y*1.2]
errorVals = [errorVals, errorVals*1.3]
serrorbars(x, y, errorVals)
SigmaPlot will create the following plot
Examples Specifying other Plot Attributes
serrorbars
argument list. If you continue the example above by entering
serrorbars(x,y,errorVals,"regression","Short dash",0.02,"blue","diamond")
SigmaPlot will create the following plot
