Excel Charting Basics About Excel Charts Building a Chart: Two Methods A Gallery of Chart Types Focus on the XY (Scatter) Chart Type Customizing a Chart

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.

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. Contents:

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

An area chart emphasizes the magnitude of change over time. By displaying the sum of the plotted values, an area chart als

The XY (Scatter) Chart Type

See the two examples below.

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.

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.

The column chart at left isn't a very satisfactory representation of the data. The X axis doesn't represent months open; months open shouldn't be plotted as columns.

The scatter plot is best suited for this data. With the data plotted as one series of XY coordinates the relationship between open months and sales amounts is much more evident.
