	`sbarh(`X`,` y`,` errors`)`
See Also	sbar , splot , spquit

Description
Create a horizontal bar graph. The argument X must be a numeric column vector or matrix. If X is a vector SigmaPlot creates a simple bar graph with N bars where N is the number of rows in X. If X is a matrix, SigmaPlot creates a grouped or stacked bar graph with M groups, and N bars per group where M is the column dimension of X and N is the row dimension of X.

The argument y is a numeric column vector which specifies the Y axis indexes at which each bar, or bar group will be placed. The argument barStyle is a character row vector which must be "stacked" or "grouped". If the barStyle argument is specified the column dimension of Y must be greater than 1. If present, the argument errors is a numeric-valued matrix with the same row and column dimensions as Y. Each column of errors specifies the error values that should be plotted for the corresponding column of X

Examples

Bar Charts Without Errors
If SigmaPlot is not running, and you enter the following at the O-Matrix prompt,




   clear

   X = {2., 2.5, 3.25}

   y = {11.25, 11.50, 11.75}

   X4 = [X, X*1.5, X*1.75, X*1.95]

   sbarh(X4)

   sbarh(X4, y, "stacked")

SigmaPlot will create the following plots

Bar Charts With Errors
If you continue the example above by entering




   sbarh(X, y, {.2, .3, .1})

   sbarh(X4, y, rand(rowdim(X4), coldim(X4))*2)

SigmaPlot will create a stacked and grouped horizontal bar chart with error bars and your notebook will look like.
