Ahelp: add_plot - ChIPS 4.1

Description

ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
px1, py1, px2, py2 - the location of the lower left (px1,py1) and upper right (px2,py2) corners of the plot. These doubles are in Frame Normalized Coordinates.
attributes - optional parameters which allow the user to configure window properties though a structure, list, or attribute string.

The add_plot command creates a plot whose attributes are specified by user preferences or in an attribute list. The new plot becomes current by default; providing a ChipsId overrides the currency state.

The plot is the object which contains axes, curves, contours, and histograms.

The lower left and upper right corner of the plot area can be specified by the add_plot() argument values (px1, py1) and (px2, py2). Otherwise a plot area is created with margins between the plot border and the frame specified by the four margin attributes: leftmargin, rightmargin, topmargin and bottommargin.

Plot Borders

Plot borders have three styles: open, box, and closed.

open: a plot with no borders
box: a plot with four simple lines as borders
closed: a plot with four border lines and tick marks

The corners where two lines meet have four styles: miter, bevel, fill, and notch.

miter: the end of the axes meet at an angle to form the corner. The slope where the two faces join depends upon the thickness of the two lines
bevel: connect the outside corners of the two lines; miter the inside faces to the bevel
fill: outside corner with one line drawn over the other
notch: leave the corners open

Plot Titles

The plot title is currently not an attribute of the add_plot command. It is set with the set_plot_title command:

set_plot_title("Figure 1");

The title is an alphanumeric string, and Latex formatting is allowed. There are many attributes to customize the title via the add_plot or set_plot commands: position, depth, horizontal and vertical alignment, angle, color, size, font and fontstyle.

Clipping

Axes, curves, lines, points and labels in data or plot normalized coordinates are clipped at the window boundaries. Only items in data coordinate systems and lines with the extend property turned on are clipped by the plot border.

Customizing the Plot

There are several attributes that control the plot characteristics. The attributes can be set to the ChIPS defaults, values provided in the add_plot command, or values from the user's preference file.

The attributes may also be modified with the set_plot command at any time; see "ahelp set_plot" and "ahelp setget" for more information.

The attributes associated with plots are:

Attribute	Description	Options	Default
bottommargin	The distance, in Frame Normalized coordinates, between the bottom plot border and the bottom border of the frame containing the plot	Real values ranging from zero through one	0.15
corner.style	border corner style	miter\|bevel\|fill\|notch; see above for descriptions	miter
leftmargin	The distance, in Frame Normalized coordinates, between the left plot border and the left border of the frame containing the plot	Zero through one	0.15
rightmargin	The distance, in Frame Normalized coordinates, between the right plot border and the right border of the frame containing the plot	Real values ranging from zero through one	0.10
stem	stem used for plot id	alphanumeric	plt
style	border style	open\|box\|closed; see above for descriptions	closed
title.angle	Angle at which the plot title is drawn	-360.0:360.0	0.0
title.color	Color of the plot title text string	name or hex; see the Color section of "ahelp chipsopt"	white
title.depth	Integer value indicating the depth of the plot title	see the Depth section of "ahelp chipsopt"	100
title.font	Plot title font	helvetica\|courier\|times\|greek; see the Font section of "ahelp chipsopt"	helvetica\|courier\|times
title.fontstyle	Specific attributes of the text string independent of size or font	normal\|bold\|italic\|bolditalic; see the Font Style section of "ahelp chipsopt"	normal
title.halign	Horizontal location of the string reference point of the plot title	auto\|base\|center\|left\|right\|top; see the Text Alignment section of "ahelp chipsopt"	center
title.size	Font size of the plot title	1:100	16
title.valign	Vertical location of the string reference point of the plot title	auto\|base\|center\|left\|right\|top; see the Text Alignment section of "ahelp chipsopt"	auto
title.xpos	X position, in Frame Normalized coordinates, of the reference point of the plot title	Real values ranging from zero through one	0.5
title.ypos	Y position, in Frame Normalized coordinates, of the reference point of the plot title	Real values ranging from zero through one	1.05
topmargin	The distance, in Frame Normalized coordinates, between the upper plot border and the upper border of the frame containing the plot	Real values ranging from zero through one	0.10

Example 3

chips> settings = ChipsPlot;
chips> settings.corner.style = "bevel";
chips> settings.style = "box";
chips> settings.stem = "MyPlot";
chips> add_plot(settings);

Populate the "settings" structure with the attribute values, then add the plot. The plot has a simple border with beveled corners.
