## Can the bars touch in a bar graph?

Bar charts have a similar appearance as histograms. However, bar charts are used for categorical or qualitative data while histograms are used for quantitative data. Also, in histograms, classes (or bars) are of equal width and touch each other, while in bar charts the bars do not touch each other.

## What part of a graph tells what the bars or lines represent?

The title of the horizontal bar graph tells about the data being represented by the graph. The vertical axis represents the data categories. Here, the data categories are the colors. The horizontal axis represents the values corresponding to each data value.

## What is an interval for a graph?

• A graph is called an interval graph if each of its vertices can be associated with an interval on the real line in such a way that two vertices are adjacent if and only if the associated intervals have a nonempty intersection. These intervals are said to form an interval representation of the graph.

## When would you use a point on a graph?

Point-to-point graphs are commonly used for portraying functions in which time is the independent variable. A point-to-point graph may be superimposed on a bar graph in a specialized plot called a Pareto chart .

## What are the points on a graph called?

Number pair – Two numbers that represent a point on a graph, also called the coordinates. Ordinate – The vertical line, or y-axis, of a graph. Origin – The origin is the point where the X and Y axis intersect on a graph. This is the point (0,0) in a two-dimensional graph.

## What two features are part of a line graph?

Constructing a Line Graph Line graphs consist of two axes: x-axis (horizontal) and y-axis (vertical), graphically denoted as (x,y). Each axis represents a different data type, and the points at which they intersect is (0,0).

## What does the line graph imply?

A line graph is commonly used to display change over time as a series of data points connected by straight line segments on two axes. The line graph therefore helps to determine the relationship between two sets of values, with one data set always being dependent on the other set.
