pgfplot-extensions

PGFPlots draws high-quality function plots in normal or logarithmic scaling with a user-friendly interface directly in TEX. And this rep is responsible for adding hci-lab helwan university extension for it

These project created by hci-lab students under Dr. waleed a. yousef supervision.

Stem and Leaf plot

A stem-and-leaf display is a device for presenting quantitative data in a graphical format, similar to a histogram , to assist in visualizing the shape of a distribution. They evolved from Arthur Bowley's work in the early 1900s, and are useful tools in exploratory data analysis. Stemplots became more commonly used in the 1980s after the publication of John Tukey's book on exploratory data analysis in 1977.

Basic usage

\stemNleaf{**data type**}{**data array**}{**fraction**}{**stem color**}{**leaf color**}{**bar color**}

\stemNleaf{10}{{1.1,2.2,3,4,5,6,7,8,9,10,11,12,17,20,22,25,29,31,43,50}}{1}{blue}{red}{green}

API Reference

\stemNleaf{**data type**}{**data array**}{**fraction**}{**stem color**}{**leaf color**}{**bar color**} \fractionalStemNleaf{**data type**}{**data array**}{**stem color**}{**leaf color**}{**bar color**}

\partialStemNleaf{**data type**}{**data array**}{**fraction**}

\fivePinsStemNleaf{**data type**}{**data array**}{**fraction**}

• Data type This parameter specify the data ranges, example: {10} this means the data maybe between 10 and 100 (has 2 digit numbers)

• Data array For this parameter user put his data, in order manner (preferred)

• Fraction Fraction is used when you do not want to round your data array, put data type equals 1 for new stem type

• Stem color Here user specify the stem color it maybe any color he want and the default is Black

• Leaf color Here user specify the leaf color it maybe any color he want and the default is Black

• Bar color Here user specify the bar color it maybe any color he want and the default is Black. The bar is divide the plot into stem and leaf.

Utility Functions

Some computational functions that helps LATEX user to perform well with any pgf-extension

Basic usage

\arrayLength{{1,2,3,4,5,6}}

API Reference

• Number of Existance Gets number of any element existance in given data array \numOfExistance{3}{{1,3,3,4,5}}

• Max Gets the maximum value of given two elements. \maxe{10}{13}

• Min Gets the minimum value of given two elements. \mine{10}{13}

• Maximum for All Gets the maximum value in the given array using natural order. \maxForAll{{1,2,3,4,5}}

• Minimum for All Gets the minimum value in the given array using natural order. \minForAll{{1,2,3,4,5}}

• Is Unique Check if the given number is exist in array and it's unqiue or not \isunique{1}{{1,2,3,4,5}}

• Array Length It gets the given array length \arrayLength{{1,2,3,4,5,6}}

• Divide and Print Once It takes array data, divide it by number and print each number exist in it once and only once \printOnce{{10,11,20,22,30,33,34}}{10}

• Divide and Check Checks if 2 values results division(with the same dominator) are equals or not (1 if equals/ 0 if not) means (A / C == B / C) or not, it checks of first two element and the third is the dominator used for division \devNck{20}{10}{10}

• Mod and Check Checks if 2 values results of modulas(with the same dominator) are equals or not (1 if equals/ 0 if not) means (A % C == B % C) or not, it checks of first two element and the third is the modulas \modNck{10}{20}{4}

There's more docs will comme, stay tuned
