JavaFX LineChart

In general, the Line Chart is defined as the type of graph in which the group of data points called markers are used to display the information.

In Line Chart, the markers are plotted on the mapping points between the two Number axes. The markers are connected by the line segments. Basically, the line chart shows the deviation in the values of one axis with respect to the change in values of other axis.
