abscissa 
the distance of a point from the vertical axis of a graph as measured parallel to the horizontal axis. (Cf. ordinate.) 
bar graph 
a graph in which numerical values of data are represented by bars of equal widths but varying lengths, also known as a bar chart. 
caption 
a heading, title, or legend for printed matter such as a magazine article, newspaper photo, or graph. [1/4 definitions] 
chart 
to display on a table or graph [1/6 definitions] 
curve 
a line graph that represents a single variable affected by changing conditions. [1/7 definitions] 
diagram 
a graph, chart, or the like. [1/4 definitions] 
graph 
to represent or express by means of a graph. [2/5 definitions] 
graphic 
of, related to, or represented on a graph. [1/7 definitions] 
histogram 
a bar graph of a frequency distribution in which the frequency of a variable is represented by the height of the bar, and the class interval by the width, where each class interval is a summary of data that represents a range of independent variable values rather than a single value. 
Laffer Curve 
a graph illustrating the theory that increasing taxes results in increased government revenue only up to a certain point, after which further tax increases discourage production and investment. 
line graph 
a graph that plots the relationship between two variable quantities, represented on horizontal and vertical axes, by connecting their coordinate points with straight lines. 
ordinate 
the distance of a point from the horizontal axis of a graph as measured parallel to the vertical axis. (Cf. abscissa.) 
pie chart 
a circular graph sectioned into pielike areas that are proportional to the quantities indicated. 
trough 
a low point on a graph, esp. a low point of a cyclic function. [1/4 definitions] 
waveform 
a mathematical representation of the form of a wave, usu. plotted as a graph.
