# Types of Line Graphs

Bar Chart Bar and column graphs are great representations of categorical data, in which you can count the number of different categories. For this example, time is continuous in the line graph. However, it can also be categorical in the bar graphs with categories of wine.

Exponential The graph is continuous; The graph is smooth; Notice the only differences regard whether the function is increasing or decreasing, and the behavior at the left hand and right hand ends. Translations of Exponential Graphs. You can apply what you know about translations (from section 1.5) to help you sketch the graph of the exponential functions.

Histogram A histogram is a type of graph that has wide applications in statistics. Histograms provide a visual interpretation of numerical data by indicating the number of data points that lie within a range of values.

Line Chart A line graph is a graphical display of information that changes continuously over time. A line graph may also be referred to as a line chart. Within a line graph, there are points connecting the data to show a continuous change.

Linear The word Linear simply means straight, so if you have a linear graph it is a straight line graphed by the equation y=mx+b where m is the slope and b is the y intercept(the point where the line crosses the y-axis).

Logarithmic A logarithmic unit is an abstract mathematical unit that can be used to express any quantity (physical or mathematical) that is defined on a logarithmic scale, that is, as being proportional to the value of a logarithm function.

Pie Chart . . . a Line graph. Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.. . . a Pie Chart. Pie charts are best to use when you are trying to compare parts of a whole.

Polynomial A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve.

Power Power View offers a number of chart options: pie, column, bar, line, scatter, and bubble. Charts can have multiple numeric fields and multiple series. You have several design options in a chart—showing and hiding labels, legends, and titles.

The simplest Quadratic Equation is: f(x) = x 2. And its graph is simple too: This is the curve f(x) = x 2 It is a parabola.

Rational To graph a rational function, you find the asymptotes and the intercepts, plot a few points, and then sketch in the graph. Once you get the swing of things, rational functions are actually fairly simple to graph. Let's work through a few examples.

Sinusoidal What are common mistakes students make with sinusoidal graphs? How do I find the equation of a sinusoidal graph? What is the graph of #y=sin^(-1) x#?
