iGraph - Advanced app for iPhone and iPad

iGraph - Advanced app helps the user to plot and create lines on a graph. A line chart or line graph is a type of chart which displays information as a series of data points connected by straight line segments.

It also gets the inputs for equations such as,
1. Straight Line
2. Parabola
a. Open Upwards
b. Open Downward
c. Open Left
d. Open Right
from the user and does the calculation to generate appropriate X & Y coordinates.

It is a type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments.

A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically.
