Constructor Details

#initialize(function, min, max, params) ⇒ FunctionPlot

  • function - a String function in Clojure Style

  • min - Lower Bound

  • max - Upper Bound

  • parms - an Hash whit parametrs value

Parms

This Hash contain parmas . List of key permitted .

  • :title - (default “A sample Graph”) Graph main title

  • :x_label - (default ‘Categories’) Label of x ass

  • :y_label - (default ‘Value’) Label of y ass

  • :legend - (default false) Prints legend

  • :height - (default 1500) Graph height

  • :width - (default 800) Graph width

  • :file_name - (default sample.jpg) Graph File Name/Path to save plot. You can chose jpg or pdf

Examples

Class Usage:

function = "(defn cubic [x] (+ (* x x x) (* 2 x x) (* 2 x) 3))" 
min = 0
max = 50
params = {"title" => "Plot my Function"}
plot = FunctionPlot.new(function,min,max,params)
#To view
plot.view 
#to save
