Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time a Bar Graph. X-Y plots are used to determine relationships between the two different things. The x-axis is used to measure. Shows the relationship of parts to a whole. Shows the relationship between two categories of data, creating data points that are unrelated to each other.

In the above example, one axis of the chart represents the categories being compared -- mobile phone manufacturers -- while the other axis lists various age ranges.

The size and color of each cross-section of the chart corresponds with the market segment it represents. Population Pyramids Market segments are often divided based on age and gender, and a population pyramid is an ideal visual representation of the two groups. The graph classically takes on the shape of a pyramid when a population is healthy and growing -- the largest groups are the youngest, and each gender dwindles somewhat equally as the population ages, leaving the smallest groups at the top of the graph.

A population pyramid that veers away from its classic shape might indicate an irregularity in a population during a particular period, such as a famine or an economic boom that led to an increase in deaths or births. A marketer, for example, might use the design to compare a population by income, weight or IQ, in which the smallest groups will often be at both the top and bottom.

Regardless, the graph clearly depicts population trends, while it compares the sizes of two related groups. The chart usually consists of a series of radii, each representing a different category, that splay out from a center point like spokes.

For each category, the spokes are then connected with a line of a designated pattern or color, forming a star-like shape with points equal to the number of categories.

The result is a graphic representation that can reveal trends and compare categories at the same time. Create marketing graphs and charts that sync with live data. Try It for Free Engineering and Technology Scatter Plots Also known as a scattergramthe graph consists of two axes, each representing a set of data. For example, one axis might represent the numbers of miles driven by a vehicle, while the second axis displays the total gallons of gas used.

For each vehicle sampled, its miles-per-gallon average is represented by a dot plotted onto the graph. Once multiple dots are plotted, trends can be spotted and samples can be compared, depending on how many colors are featured in the chart. What if, for example, a graph needs to compare not only miles driven and gallons used, but also the number of gears and cylinders contained in each vehicle sample?

A trellis plot, also called a lattice graph or plot, can display and compare all of those variables. While the above example uses a series of scatter charts, trellis plots commonly feature series of bar or line graphs, as well.

Function Plots Mathematicians, engineers and statisticians often need to determine the value of an equation by graphing its result. The graph of a function is the set of all points whose coordinates satisfy the equation. Therefore, the function of an equation with variables of x and y would be drawn on a graph with an x and y axis.

Likewise, an equation that also included a variable of z would need to be drawn on a three-dimensional graph with a third axis.

Function graphs of common shapes are visually associated with their corresponding algebraic formulas. Binary Decision Diagrams A binary decision is a choice between two alternatives, so a binary-decision diagram illustrates the path from one decision to another. In computer science, binary decisions make up the Boolean data type, in which two values are associated with different actions within a process flow.

Outside of computer science, a binary-decision diagram can still be used to illustrate any process by which actions are based on a decision between two values, whether those conditions be yes or no, true or false, 1 or 0 or any other opposing choices. Ultimately, the path taken will diagram how the process flowed, from beginning to end.

Circuit Diagrams Just as its name implies, a circuit diagram is a visual representation of an electrical circuit.

Using simple shapes and images, the diagram illustrates the components and interconnections of a circuit, from start to finish. While the pathways and connections are accurate, the diagram does not necessarily represent a proportionate spatial construction of the circuit.

In computer science, circuit diagrams are useful in depicting data related to both hardware and software.

How many parts make a whole?

The graphics not only pictorialize the pathways of a circuit in the literal sense, but they are also closely related to the aforementioned binary-decision diagram -- both are used to diagram programming process flows. Create graphs and charts that sync with live data. A stacked bar graph combines elements of the traditional bar graph and the pie graph to communicate totals, trends and proportions in a single illustration.

For example, rather than simply illustrating changes in global population over time with a traditional column bar graph, a stacked bar graph can also represent the racial makeup of the total population during each year and how those proportions have changed during the same period.

## Available chart types in Office

You can pull out slices of a pie chart manually to emphasize the slices. Doughnut charts Data that's arranged in columns or rows only on a worksheet can be plotted in a doughnut chart.

Like a pie chart, a doughnut chart shows the relationship of parts to a whole, but it can contain more than one data series. Doughnut charts aren't easy to read. You may want to use a stacked column charts or Stacked bar chart instead. Bar chart Data that's arranged in columns or rows on a worksheet can be plotted in a bar chart. Bar charts illustrate comparisons among individual items. In a bar chart, the categories are typically organized along the vertical axis, and the values along the horizontal axis.

Consider using a bar chart when: The axis labels are long. The values that are shown are durations. Area chart Data that's arranged in columns or rows on a worksheet can be plotted in an area chart.

Area charts can be used to plot change over time and draw attention to the total value across a trend. By showing the sum of the plotted values, an area chart also shows the relationship of parts to a whole. As a rule, consider using a line chart instead of a non-stacked area chart, because data from one series can be hidden behind data from another series. A 3-D stacked area chart does the same, but it shows areas in 3-D format without using a depth axis. XY scatter and bubble chart Data that's arranged in columns and rows on a worksheet can be plotted in an xy scatter chart.

Place the x values in one row or column, and then enter the corresponding y values in the adjacent rows or columns. A scatter chart has two value axes: It combines x and y values into single data points and shows them in irregular intervals, or clusters. Scatter charts are typically used for showing and comparing numeric values, like scientific, statistical, and engineering data. Consider using a scatter chart when: You want to change the scale of the horizontal axis.

You want to make that axis a logarithmic scale. Values for horizontal axis are not evenly spaced. There are many data points on the horizontal axis. You want to adjust the independent axis scales of a scatter chart to reveal more information about data that includes pairs or grouped sets of values.

You want to show similarities between large sets of data instead of differences between data points. You want to compare many data points without regard to time—the more data that you include in a scatter chart, the better the comparisons you can make. Smooth lines can be shown with or without markers. Use a smooth line without markers if there are many data points. Straight lines can be shown with or without markers. Much like a scatter chart, a bubble chart adds a third column to specify the size of the bubbles it shows to represent the data points in the data series.

The third value specifies the size of the bubble marker. Stock chart Data that's arranged in columns or rows in a specific order on a worksheet can be plotted in a stock chart. As the name implies, stock charts can show fluctuations in stock prices. However, this chart can also show fluctuations in other data, like daily rainfall or annual temperatures.

Make sure you organize your data in the right order to create a stock chart. They display hierarchical information as a cluster of rectangles varying in size and color, depending on their data value. The size of each rectangle represents a quantity, while the color can represent a number value or a category. Treemaps allow you to view trends and make comparisons quickly — especially if one color is particularly prominent. While spreadsheets can show multiple rows of data, treemaps can accommodate hundreds of thousands of items in one organized display, making it easy to spot patterns in seconds.

Plus, if made correctly, they make very efficient use of space. Best practices for creating a Treemap Start with clean data and a clear message - Treemaps can often involve a lot of data, so it's important to know exactly what you want to highlight.

Use bright, contrasting colors so each region is easily de ned - But, remember to avoid the 'rainbow e ect. Avoid clutter your treemap with too many boxes - Treemaps can contain any number of boxes, but space is limited!

You don't want your treemap to be hard to read. Dual Axis Chart With a dual axis chart you are essentially combining multiple charts and adding a second y-axis for comparison. Some members of the data visualization community are skeptical about the use of dual axis charts because they can often be confusing, poorly designed, and misleading to the viewer. Column and Line Chart— This dual axis chart combines a column chart with a line chart.

## How to Choose the Right Chart for Your Data

Dual Line Chart — This dual axis chart compares two line charts. There can be more than two lines if need be. Dual Column Chart— This dual axis column chart shows two sets of data displayed side by side. Multiple Axes Chart — This displays the most complex version of the dual axis chart. Here you see three sets of data — with three y-axes. Area Chart Area charts are a lot like line charts, with a few subtle differences. They can both show change over time, overall trends, and continuity across a dataset.

But, while area charts may function the same way as line charts, the space between the line and axis is filled in, indicating volume. Best practices for creating Area charts Make it easy to read - Avoid occlusion. This happens when one or more layers covers important information on the chart. Use a stacked area chart - If you have multiple data sets and want to emphasize part-to-whole relationships. Use area charts to look at the bigger picture - Take population for example: Line charts are good for showing net change in population over time, while area charts are good for showing the total population over time.

Avoid comparing too many datasets. Use instead a line chart, its cleaner. Give the proper context with appropriate labels and legends. Pyramid Chart Pyramid charts triangle chart or triangle diagram are a fun way to visualize foundation based relationships. They can be oriented up or down depending on the relationships they represent. The stacked layers can also show the order of steps in a particular process. Best practices for creating Pyramid Charts Pick a topic and clearly label your subcategories - Decide what information you want to convey with your pyramid and clearly label your layers.
