== BAR CHARTS ==
== XY PLOT ==

==Background ==

When comparing groups of data, Bar Charts are one of the best approaches for single category data analysis.

With two variables, X and Y, these Bar Charts are used for displaying the values for each variable represented by column length extending from each X-Y point. Each bar shows the contribution of two or more variable or the total, and the length is the sum of the parts that make up the total data set.

== Description ==

Go to the SOCR Charts and select Bar Charts from the items located on the left. Then select XY Plot:

The first two set of demonstrations are basic XY Plot Bar Charts:

The Histogram Demonstration Charts are categorized as XY Plot Charts because they display the values for each variable. One difference from the Histogram Bar Charts is that the Dependent variable is the Frequency, or how many times the specific data appears, of the data set.

== Applications ==

One of the most persuasive elements when proposing data and literature to others is a well-designed chart presentation. The XY Plot Bar Charts are very useful when comparing two variables of data.

For example, suppose students are issued a project to compare the opinions of favoring soda between age groups. The Independent variable may be intervals of every 5 years among their sample of population, and the dependent variable may represent the outcome of the individual preferences.

For industries, XY Plot Bar Charts may be applied to illustrate their growth of the company in regards to their production.

		+	By clicking '''Data''' inbetween the ''Graph'' and ''Mapping'' button, it allows users to input or vary the values of the data set. There are two different types of data that is allowed for plotting data points which are the independent variable (e.g., Series Number, Time, Date, etc.) and the dependent variable (e.g., Frequency, Values, etc.). The image below illustrates this:
