legend_line_style(type:line_style.T) default="The line style used to draw a legend entry. Usually, the value is None, meaning that the value of "line_style" attribute is used.".

error_bar(type:error_bar.T) default="Specifies the style of the error bar. <<error_bar>>".

data_label_format(type:printf format string) default="The

format string for the label displayed besides each

bar. It can be a `printf' style format

string, or a two-parameter function that

takes (x,y) values and returns a string. The appearance of the string produced here can be

controlled using escape sequences. <<font>>".

width(type:length in points (\\xref{unit})) default="Width of each box.

@cindex width, bar chart

@cindex size, bar chart

bcol(type:int) default="Specifies the column from which base values (i.e., X values when attribute "direction" is "vertical", Y values otherwise) are extracted.

The

combination of "data", "bcol", and "hcol" attributes defines

the set of boxes drawn by this chart. See the

below example:

@example

d = [[5,10], [7,22], [8,25]]

p = bar_plot.T(data = d, bcol = 1, hcol = 2)

@end example

Here, three bars will be drawn. The X values of the bars

will be 5, 7, and 8. The Y values of the bars will be

10, 22, and 25, respectively. (In practice, because

the values of bcol and hcol defaults to 1 and 2, you can

write the above example just as "p = bar_plot.T(data = d)".

qerror_minus_col(type:int) default="The depth of the "quartile" errorbar is extracted from

this column in data. This attribute is meaningful only

when error_bar != None. ".

_abs_data(type:list) default="Used only internally.".

label(type:str) default="The label to be displayed in the legend. <<legend>>, <<font>>".

cluster(type:tuple) default="This attribute is used to

cluster multiple bar plots side by side in a single chart.

The value should be a tuple of two integers. The second value should be equal to the total number of bar plots in the chart. The first value should be the relative position of this chart; 0 places this chart the leftmost, and N-1

(where N is the 2nd value of this attribute) places this chart the rightmost. Consider the below example:

@example

a = area.T(...)

p1 = bar_plot.T(data = [[1,20][2,30]], cluster=(0,2))

p2 = bar_plot.T(data = [[1,25],[2,10]], cluster=(1,2))

a.add_plot(p1, p2)

a.draw()

@end example

In this example, one group of bars will be drawn side-by-side at

position x=1, one with height 20, the other with height 25. The

other two bars will be drawn side by side at position x=2, one

with height 30 and the other with height 10.

hcol(type:int) default="The column from which the height of each bar is extracted.

See also the description of the 'bcol' attribute.".

stack_on(type:any) default="The value must be either None or bar_plot.T. If not None, bars of this plot are stacked on top of another bar plot.".

qerror_plus_col(type:int) default="The depth of the "quartile" errorbar is extracted from

this column in data. This attribute is meaningful only

when error_bar != None.".

data_label_offset(type:(x,y)) default="The location of data labels relative to the sample point. See also attribute data_label_format.".

fill_style(type:fill_style.T) default="Defines the fill style of each box.".

The style is picked from standard styles round-robin.

data(type:any) default="Specifies the data points. <<chart_data>>".

line_style(type:line_style.T) default="The style of the outer frame of each box.".

legend_fill_style(type:fill_style.T) default="The fill style used to draw a legend entry. Usually, the value is None, meaning that the value of "fill_style" attribute is used.".

error_minus_col(type:int) default="Specifies the column from which the depth of the errorbar is extracted. This attribute is meaningful only when

error_bar != None.
