| Standard parameters |
|
|
All of the standard prefab parameters may be used.
You must specify data (the name of the input data file).
|
| x |
data field |
must be specified |
Identifies the data field that will hold X component.
By default these are assumed to be categories, but thay can be continuous numeric values
if the xnumeric parameter is specified. |
x=2
x=pmb |
y
y2 |
data field |
y must be specified |
Identifies the data field(s) that will hold Y component.
Data must be numeric.
If y and y2 are specified, two sets of bars will be produced. |
y=3
y=cfr y2=cfl |
err
err2 |
data field |
|
Identifies the data field(s) that will hold error amount, such as SD.
Data must be numeric.
| err=4
err=cfr_sd err2=cfl_sd |
color
color2 |
color |
orange, powderblue |
Color of bars. |
color=green |
| barwidth |
inches or cm
or
line |
based on data |
Specifies the width of the filled bars. May be given as line to produce very thin bars.
The default bar width is not always appropriate.
|
barwidth=0.05
barwidth=line |
| truncate |
yes | no |
no |
If yes, bars that stray beyond the plotting area are truncated. (Added in 2.42)
|
truncate=ye |
errcolor
errcolor2 |
color |
black |
Color of error bars. |
errcolor=gray(0.4) |
| errwidth |
inches or cm
or
line |
0.08 " |
Width of error bar tails. |
errwidth=0.1 |
| errthick |
line thickness value |
0.5 |
The thickness of the error bar lines (default = 0.5) |
errthick=1 |
| erroneway |
yes or no |
no |
Draw one-way upward error bars instead of the usual symmetrical error bars.
Old name: errunder |
erroneway=yes |
| erronly |
yes or no |
no |
If yes, render error bars only.
y will control the location of the center of the bar and err
will control the error amount. |
erronly=yes |
| xnumeric |
yes or no |
no |
If yes, signifies that X values are numeric rather than categories. |
xnumeric=yes |
| vals |
yes or no |
no |
If yes, display numeric values near the top of each bar. |
vals=yes |
| crossover |
Y value |
|
A value in Y where bars begin
to point downward instead of upward. For instance, crossover=0
is often useful when dealing with financial income, to show loss
using downward bars. |
crossover=0 |
curve
order |
yes
or
linedetails |
|
Generate a moving average curve fit to the bars. It will be drawn behind
the bars. Not applicable to a second set of bars.
order is an attitional parameter may be set to the number of preceding
data points to be considered when computing averages (default = 5).
|
curve=yes
"curve= color=blue" |
| sep |
inches or cm |
0.15 " |
Controls bar separation when two bar sets are being rendered. |
sep=0.08 |
