"PDL::Graphics::PGPLOT" is a convenience interface to the PGPLOT commands, implemented using the object oriented PGPLOT plotting package in PDL::Graphics::PGPLOT::Window. See the documentation for that package for in-depth information about the usage...

This package offers a OO interface to the PGPLOT plotting package. This is intended to replace the traditional interface in PDL::Graphics::PGPLOT and contains interfaces to a large number of PGPLOT routines. Below the usage examples for each function...

This package contains one function (at present) which returns PDL::Option objects for default settings for plot windows and plot commands. This should be complemented by functions that could affect this such as file reading commands etc....

This module contains basic utility functions for creating and manipulating piddles. Most of these functions are simplified interfaces to the more flexible functions in the modules PDL::Primitive and PDL::Slices....

The terms FUNCTIONS and METHODS are arbitrarily used to refer to methods that are threadable and methods that are NOT threadable, respectively. Plots require PDL::Graphics::PGPLOT. ***EXPERIMENTAL!*** In particular, bad value support is spotty and ma...

The terms FUNCTIONS and METHODS are arbitrarily used to refer to methods that are threadable and methods that are NOT threadable, respectively. FUNCTIONS except ols_t support bad value. PDL::Slatec strongly recommended for most METHODS, and it is req...

Parameter estimate is maximum likelihood estimate when there is closed form estimate, otherwise it is method of moments estimate....

Assumes that we have data pdl dim [observation, variable] and the goal is to put observations into clusters based on their values on the variables. The terms "observation" and "variable" are quite arbitrary but serve as a reminder for "that which is ...

PDL::Graphics::LUT contains a number of colour look-up tables (in rgb format) and intensity ramps, and provides routines to access this data. The format of the data is suitable for use by ctab. Unlike the initial release of the package, the data tabl...

PDL::Graphics::Prima is a plotting library for 2D data visualization. The core of this library is a Plot widget that can be incorporated into Prima applications. The library produces publication quality static figures, but its true potential lies in ...

This is the PDL interface to the PLplot graphics library. It provides a familiar 'perlish' Object Oriented interface as well as access to the low-level PLplot commands from the C-API....

Functions to derive limits for data for display purposes...

This module allows PDL data to be plotted using Gnuplot as a backend for 2D and 3D plotting and image display. Gnuplot (not affiliated with the Gnu project) is a venerable, open-source program that produces both interactive and publication-quality pl...

PDL can plot through a plethora of external plotting modules. Each module tends to be less widely available than Perl itself, and to require an additional step or two to install. For simple applications ("throw up an image on the screen", or "plot a ...

A OO X Windows fits image display module built on PDL::Graphics::X. This module draws fits image with appropriately labeled axises & tick marks, similar to those drawn by PGPLOT. Once the image has been displayed, the cursor method will return the lo...

PDL::Transform::Cartography includes a variety of useful cartographic and observing projections (mappings of the surface of a sphere), including reprojected observer coordinates. See PDL::Transform for more information about image transforms in gener...
