"iGraph - Basic" 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 is a basic 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.
