About Excel Charts

An Excel chart provides a graphical view of worksheet data.

A chart is linked to the worksheet data from which it's

created. When the worksheet data changes, the chart

changes automatically.

Charts are almost infinitely customizable. For example:

Even after your chart is created, you can add data to it or

delete data from it.

Change the chart type at any time.

Right-click almost any element of a chart to see its

context menu; then modify the element.

Add your own text to a chart.

Use graphics (instead of geometric shapes) as data markers.

Etc.

A chart in a worksheet "floats" on the surface of the sheet. You

can move a chart "over" worksheet contents without disturbing them.

Method 1

Select the data to chart (B4:E7).

Hit the F11 key.

Excel creates the default column chart and

locates it on a new worksheet.

Method 2

Select the data to chart (B4:E7).

Go through the 4 Chart Wizard steps.

Excel creates the chart based on your

Wizard-prompt selections.

Chart Types: A Gallery of Chart Examples

From: http://office.microsoft.com/assistance/2002/articles/ExamplesofChartTypes.aspx

Excel supports many kinds of charts to help you display data in ways that are most

meaningful to your audience. Here's a gallery of chart examples to help you

determine which kinds of charts are best for your data.

XY Scatter Bubble

Radar Surface

Cone, Cylinder, Pyramid Area

Column Bar

XY scatter

An xy (scatter) chart either shows the relationships among the numeric values in several data series, or plots two groups of numbers as one series of xy coordinates. This chart shows uneven intervals &151; or clusters &151; of data and is commonly used for scientific data.

When you arrange your data, place x values in one row or column, and then enter corresponding y values in the adjacent rows or columns.

Bubble

A bubble chart is a type of xy (scatter) chart. The size of the data marker indicates the value of a third variable.

To arrange your data, place the x values in one row or column, and enter corresponding y values and bubble sizes in the adjacent rows or columns.

The chart in this example shows that Company A has the most products and the greatest market share, but not the highest sales.

Radar

A radar chart compares the aggregate values of a number of data series.

In this chart, the data series that covers the most area, Brand A, represents the brand with the highest vitamin content.

Surface

A surface chart is useful when you want to find optimum combinations between two sets of data. As in a topographic map, colors and patterns indicate areas that are in the same range of values.

This chart shows the various combinations of temperature and time that result in the same measure of tensile strength.

Cone, Cylinder, Pyramid

The cone, cylinder, and pyramid data markers can lend a dramatic effect to 3-D column and bar charts.

Area

An area chart emphasizes the magnitude of change over time. By displaying the sum of the plotted values, an area chart also shows the relationship of parts to a whole.

In this example, an area chart emphasizes increased sales in Washington and illustrates the contribution of each state to total sales.

Column

A column chart shows data changes over a period of time or illustrates comparisons among items. Categories are organized horizontally, values vertically, to emphasize variation over time.

Stacked column charts show the relationship of individual items to the whole. The 3-D perspective column chart compares data points along two axes.

In this 3-D chart, you can compare four quarters of sales performance in Europe with the performance of two other divisions.

Bar

A bar chart illustrates comparisons among individual items. Categories are organized vertically, values horizontally, to focus on comparing values and to place less emphasis on time.

Stacked bar charts show the relationship of individual items to the whole.

Line

A line chart shows trends in data at equal intervals.

Pie

A pie chart shows the proportional size of items that make up a data series to the sum of the items. It always shows only one data series and is useful when you want to emphasize a significant element.

To make small slices easier to see, you can group them together as one item in a pie chart and then break down that item in a smaller pie or bar chart next to the main chart.

Doughnut

Like a pie chart, a doughnut chart shows the relationship of parts to a whole, but it can contain more than one data series. Each ring of the doughnut chart represents a data series.

Stock

The high-low-close chart is often used to illustrate stock prices. This chart can also be used for scientific data; for example, to indicate temperature changes. You must organize your data in the correct order to create this and other stock charts.

A stock chart that measures volume has two value axes: one for the columns that measure volume, and the other for the stock prices. You can include volume in a high-low-close or open-high-low-close chart.

The XY (Scatter) Chart Type

An xy (scatter) chart either shows the relationships among the

numeric values in several data series, or plots two groups of

numbers as one series of xy coordinates. The XY chart shows uneven

intervals or clusters of data and is commonly used for scientific

data. When you arrange your data, place x values in one row or column,

and then enter corresponding y values in the adjacent rows or columns.

Example 1:

At left is data collected from five retail stores. For each store, we have information about how long the store has been open and it's average monthly sales. We need to create a chart that shows the relationship between length of time open and sales.

to the modified chart.

6. Location & Printing

The last Chart Wizard step gives you the choice of

embedding your chart in the same worksheet with the data that Excel adds to the workbook. Whatever you decide in this step, you can always change your mind later.

To move a chart from its own sheet to another

worksheet, right click the chart and choose Locationdifferent worksheet. Use the same technique move a chart embedded on a sheet to its own worksheet.

To print a chart on its own worksheet choose File, Print from the menus.

Or, for more options in how the chart will display on the page, choose File, Page Setup and click the "Chart" tab. Select from the "Printed chart size" options. To print only the chart on a worksheet with data, click the chart to select it and then choose File, Print or File, Page Setup. The same print options described above apply.

To print a chart AND other data on the same worksheet, highlight the range that includes the data and the chart and choose File, Print and then "Selection". Then choose Preview mode to see what Excel will print.

Do you want Months to display on the X axis and Widget items to display in the legend or the reverse?
