In other words, a histogram provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values (called "bins"). Plotting a histogram using hist from the graphics package is pretty straightforward, but what if you want to view the density plot on top of the histogram?This combination of graphics can help us compare the distributions of groups. For example: one histogram for sepal width, another for sepal length, and so on. As exhibited in the experiments the proposed system achieved promising results when comparing with different systems in the literature in term of accuracy and speediness. However we may find the default number of bins does not offer sufficient details of our distribution. Link to a live example. The input screen for "Multiple Histograms" is shown. We can put multiple graphs in a single plot by setting some graphical parameters with the help of par() function. Selecting different bin counts and sizes can significantly affect the shape of a histogram. It is also possible to make a matrix of scatterplots if you would like to compare several variables.
