Histogram Java chart is a specialized type of Bar chart which is also a part of ElegantJ Chart Library. The strength of a histogram is that it provides an easy-to-read picture of the location and variation in a data set.
Components and functions of Histogram Charts:
A Histogram Chart has the charting format that displays horizontal or vertical bars.
The length of the bars is set in proportion to the values of the data items they represent.
The individual data points are grouped together in classes, to get an idea of how frequently data
in each class occur in the data set.
High bars in Histogram charts indicate more points in a class and low bars indicate lesser points.
However, the weakness of this type of chart is that it can be manipulated to show different pictures.
If too few or too many bars are used, the histogram can be misleading.
Histogram chart components can obscure the time differences among data sets.
