AHELP for ChIPS 4.0

chipsopt

Context: py.chips

Synopsis

The ChIPS Dictionary is a glossary of frequently-used terms and attribute value listings.

Description

Numerous object attributes are represented as boolean states, such as object visibility and fill properties. Behaviors like auto limit calculations are also boolean.

Depending on the context, a boolean value may be specifed as an integer or a string value. For example, when using an attribute string, the string values are used ("fill=true"), but when using an attribute list to set values either a numeric or a string may be used ({"fill",1} or {"fill","true"}). For integer representations, a 0 equates to false while a 1 equates to true. For string representations, a wide range of values may be used to specify the boolean settings.

The predefined Python True and False boolean values are also supported.

Values	Description
0	represents a numeric off or false state
1	represents a numeric on or true state
false, f, no, n, off, 0	represents a string off or false state
true, t, yes, y, on, 1	represents a string on or true state

Color

Description

Color is an attribute of nearly all objects in ChIPS, and there is a vast palette available. The Colors help file ("ahelp py.chips colors") describes how to specify color values and how to set the color attributes of objects.

Since the colors used for video displays are often not optimal for hardcopies, ChIPS provides a special color identifier "default". Any item set to "default" will use user-configurable default colors for foreground and background colors in terminals as well as hardcopies; refer to "ahelp py.chips colors" for more information.

Values

Colors may be specified by name ( "lime", "gray", "black") or as hex values (RRGGBB where 0xff0000 = Red, 0x00ff00 = Green, 0x0000ff = Blue).

Contour Mode

Description

The contour mode sets how levels are determined in contours.

Values

The following contour modes are supported:

Name	Enumeration	Description
arbitrary	chips_arbitrary	utilizes the user specified contour levels
count	chips_count	generates the specified or default number of contour levels
interval	chips_interval	generates contour levels at the specified or default interval
limits	chips_limits	attempt to generate approximately 5 contour levels. Same as "nice" mode
nice	chips_nice	attempt to generate approximately 5 contour levels. Same as "limits" mode

Depth

Description

Depth control allows the user to specify the depth at which each object is placed within a frame. The "ahelp py.chips depthcontrol" file has complete details on using and setting depths.

When objects are created, they are assigned a depth value. The depth to which an object is assigned, along with the order that the objects were added to the depth, determines the rendering order of the frame. Depths are rendered from the lowest depth value greater than 0 to the highest depth value in use. Objects at higher depths may overlap lower objects.

Values

Depths are specified as positive integers where the value 1 represents the lowest items ("farther" from the top).

The depth value 0 ("default", V_USE_DEFAULT_DEPTH) represents a special case. If the value is default, then default frame depth is used. The value of the frame default is initialized to the value of the preference "default.depth", but may be modified by using the set_default_depth command. The new setting does not affect the depth of existing objects, only new ones created after the call to set_default_depth.

Export

Description

Export attributes are used to control the output files generated by ChIPS. Users may specify various file formats. In addition, color format, scaling, margins, and other attributes of the output may be specified.

Values

Attributes that are specific to page layouts (margins, page size, orientation, etc.) only apply to pdf and ps formats.

Font

Description

ChIPS provides four installed fonts: times, helvetica, courier, and greek.

In addition to the standard fonts, ChIPS provides limited support for users to load their own fonts. The user-loaded fonts work on the screen displays, but all hardcopy output formats only support the built-in fonts. Furthermore, the user-loaded fonts do not get saved in state files.

       load_font("bookman","/my_fonts/bookman.pfb", chips_normal)
       load_font("bookman","/my_fonts/bookman_b.pfb", chips_bold)
       load_font("bookman","/my_fonts/bookman_i.pfb", chips_italic)
       load_font("bookman","/my_fonts/bookman_bi.pfb", chips_bolditalic)
       add_label(.1,.5,"AbCdEfGhIjKlM","font=bookman fontstyle=bold")

Object Type

Description

ChIPS utilizes various objects to create figures. It is necessary to specify the object to which an action should be applied when using any of the non-object-specific commands, e.g. move, shuffle, set_attribute.

Values

Object type are represented as an enumeration in ChIPS. It is possible to specify an object type using either the enumeration (chips_line) or its numeric value (11 for chips_line).

Name	Enumeration	Numeric	Description
window	chips_window	2	a window object
frame	chips_frame	3	a frame object

Text Alignment

Description

Text alignment determines how a label is displayed in relation to the associated location. It is sometimes referred to as text justification. For instance, text that is left-justified has its leftmost edge placed at the specified location or reference point. Right-justified means the text is placed so that the rightmost portion of the label ends at the specified location.

For vertical alignment the baseline of the text (neglecting descenders such as "p", "g", or "q") is the 0 or base. The top is determined by the height of standard glyphs in the label.

Values

Text Alignments may be specified as numeric values or as the predefined values specified in the table below. Numeric values greater than 1 or less than 0 result in the labels shifting over by a ratio based on the height or width of the text. For instance, a horizontal alignment of -1 will place the label to the right of anchor position, by the length of the label.

Value	Numeric	Horizontal Use	Vertical Use
auto	-99.0	determines the appropriate reference position based on the type and position of object	determines the appropriate reference position based on the type and position of object
base	0.0	N/A	places the reference position at the text baseline
center	0.5	places the reference position in the center of the text.	places the reference position in the center of the text.
left	0.0	places the reference position at the start of the text string	N/A
right	1.0	places the reference position at the end of the text string	N/A
top	1.0	N/A	places the reference position at the top of the text

Text Formatting

Thickness

Description

Thickness is a property of objects which display line segments, such as curves, contours, and regions.

Values

Thickness is specified as a floating point value which may range from 0.5 to 10.0. Screen displays typically represent line thickness as integer values, but floating point specifications are supported for postscript output. While a value of 0.5 and 1 will appear differently in postscript output, they will both appear as a thickness of 1 in the screen display.

Tick Format

Description

Tick formats allow the user to specify the appearance of axis tick labels. The syntax is similar to that of the C printf format strings: "%<qualifier><format>". Text may be included before or after the qualifier.

The default tick format is %g.

      set_axis("ay1",["tickformat","distance %2.1f km"])

Tick formats do not support latex conventions.

Values

The following tick formats are supported:

Tick Mode

Description

Tick modes control the placement of tick marks on an axis. There are different modes which may be utilized. Two of the modes automatically determine tick locations based on the values of the data being plotted. The other three use data-independent values.

Changing the values associated with interval, count, or arbitrary tick marks (majortick.interval, majortick.count, and arbitrary tick positions respectively) will result in the axis automatically changing to the appropriate tick mode.

Changing the tick mode may result in a change in the range of one or more axes.

Values

The following tick modes are supported; details on each follow the table.

Name	Enumeration	Description
arbitrary	chips_arbitrary	places tick marks at user specified locations
count	chips_count	attempts to display the user specified number of tick marks
interval	chips_interval	spaces tick marks at the user specified interval
limits	chips_limits	calculate tick marks to be spaced on "nice" intervals (factors of 1,2,5,10) and pad axes ends; recommended for use with log axes
nice	chips_nice	calculate tick marks to be spaced on "nice" intervals (factors of 1,2,5,10) ending on major ticks; recommended for use with log axes

Arbitrary tick mode allows the user to specify the exact locations of the tick marks. ASCII text values may be used instead of numeric values, but there must be 1-to-1 mapping between the arbitrary locations and the specified text.
Count tick mode allows the user to request a number of tick marks to be displayed. ChIPS will attempt to place the requested number of tick marks at "nice" locations. If nice placement can not be achieved with the specified numer of tick marks, ChIPS will display more or less than the requested number. The "majortick.count" value serves as a guideline for count mode.
Interval tick mode uses a configurable interval value to determine where to place the tick marks. Tick locations are calculated at the specified interval using 0 as a reference point. For instance, a majortick.interval of 7 would place ticks at 7, 14, 21, 28, 35, ... If the range of the data is smaller than the interval, zero or one tick marks will be displayed.
Limits and nice tick modes automatically adjust the tick mark locations based on the range of the data (or user specified limits). These modes attempt to position the ticks using intervals that are generally factors of 1, 2, 5, 10 such that approximate four to six tick marks are displayed. Nice mode starts and ends on tick marks, while limits mode provides a pad factor so that the tick marks are buffered by a configurable padding percentage.

Tick Style

Description

Tick styles specify how the tick marks are placed on an axis. They may centered on the axis such that they extend evenly above and below the axis. They may also extend out in only one direction from the axis. In the latter case, the location of the axis determines which way the tick marks should extend.

The direction of the tick styles refer to axes that are specified in Plot Normalized or Data coordinates. Axes that are specified in other coordinates may behave differently. For instance, an axis specified in Frame Normalized coordinates has the reference point at the center of the frame rather than the center of the plot when determining the direction of "inside" or "outside".

Values

The following tick values are supported:

Name	Enumeration	Numeric	Description
inside	chips_inside	0	tick marks face towards the center of the plot
outside	chips_outside	1	tick marks face away from the center of the plot
centered	chips_centered	2	tick marks are centered on the axis baseline
