The Line graph is a pictorial representation of data and helps determine trends and rates of change. The slope of the graph helps in computing the magnitude of change between two consecutive points. This graph is similar to the bar graph except for the fact that here data is in nature of the flow mode, and not discrete. The line graph indicates changes in plotted variables with respect to the two indices calibrated on the X and the Y axes respectively. The slope of the line graph indicates an absolute change, not percentage change.
