Ahelp: sherpa.fitplot

Description

The Sherpa configuration variable (also called "state object") sherpa.fitplot controls appearance of plots created by LPLOT BACKFIT, LPLOT BFIT, and LPLOT FIT . The settings of sherpa.fitplot do not affect plots created with any other command.

The following table lists each field of sherpa.fitplot, with a description and the default value:

Field Name	Description	Default
x_errorbars	Add x-axis error bars to data points (0 = false, 1 = true)	0
y_errorbars	Add y-axis error bars to data points (0 = false, 1 = true)	1
errs_style	Style of error bars	bar
errs_type	Direction of Error bars: up, down (or both).	both
x_log	Log scale for x-axis (0 = false, 1 = true)	0
y_log	Log scale for y-axis (0 = false, 1 = true)	0
curvestyle	Style of curve (e.g., histogram)	noline
curvecolor	Curve color	default
symbolstyle	Style of symbols (e.g., triangle, square)	square
symbolcolor	Symbol color	default
symbolsize	Symbol size	2
fit_curvestyle	Style of 2nd, predicted data curve	step
fit_curvecolor	Color of 2nd, predicted data curve	red
fit_symbolstyle	Style of symbols of 2nd, predicted data curve	square
fit_symbolcolor	Symbol color	Color of symbols of 2nd, predicted data curve
fit_symbolsize	Size of symbols of 2nd, predicted data curve	2
xlabel_size	Size of x label	1.5
ylabel_size	Size of y label	1.5
zlabel_size	Size of z label	1.5
title_size	Size of title	1.5
tickvals_size	Size of tick values	1.5
prefunc	User S-Lang function executed before the data is plotted	NULL
postfunc	User S-Lang function executed after the data is plotted	NULL

Possible error bar styles: standard, bar.

Possible error bar types: both, none, up, down, dn.

Possible colors: black, blue, cyan, default, green, magenta, red, white, yellow.

Possible curve styles: histo, noline, simpleline, step.

Possible symbol styles: bigpoint, block, circle, cross, diamond, downtri, none, point, soliddiamond, soliddowntri, soliduptri, square, uptri.

The fields sherpa.fitplot.prefunc and sherpa.fitplot.postfunc refer to optional user functions that can be applied to plots before and after the plot is created. Please see the ahelp file sherpa-plot-hooks for more information.
