Call: PLOT_BARCHART

x

A Matrix which contains the ordinates of the bars to be plotted.

This argument does not have to be 1-dimensional - the structure of the argument matrix is ignored - but the overall length has to be the same as that of the coordinate vector y.

[This argument is mandatory. No default is supplied.]

y

A Matrix which contains the coordinates of the bars to be plotted.

This argument does not have to be 1-dimensional - the structure of the argument matrix is ignored - but the overall length has to be the same as that of the ordinate vector x.

[This argument is mandatory. No default is supplied.]

x_label

The String that should appear along the horizontal axis.

The label is shown using the text representation LABELS.

If omitted or if specified as `*`, the name of the global variable associated with the ordinate vector x will be used, unless this vector is the result of an operation, in which case the string `Ordinate` will be shown.

This argument is ignored if the NOFRAME option is in effect.

y_label

The String that should appear along the vertical axis.

The label is shown using the text representation LABELS.

If omitted or if specified as `*`, the name of the global variable associated with the coordinate vector y will be used, unless this vector is the result of an operation, in which case the string `Coordinate` will be shown.

This argument is ignored if the NOFRAME option is in effect.

title

This should be a String that contains the title that you want to appear at the top of the plot.

The title is shown using the text representation TITLE.

If omitted or if specified as `*`, a name will be constructed from the global variables from which the plot is made. If one of these is the result of an operation, then the string `Title` will be used.

This argument is ignored if the NOFRAME option is in effect.

options

A String which can contain the following options:

Option	Effect	Notes
`FRAME`	Plots the bar chart with a frame	Default
`NOFRAME`	Reuses the existing frame	Not default

representations

The first histogram in a frame is drawn using the BARCHART-1 representation, the 2nd using BARCHART-2, the third with BARCHART-3 etc.

The counter is reset each time a plot is started or completed.
