0i. Charts:
A chart is a visual representation of numeric values. Charts (also known as graphs) have been an integral part of spreadsheets. Charts generated by early spreadsheet products were quite crude, but thy have improved significantly over the years. Excel provides you with the tools to create a wide variety of highly customizable charts. Displaying data in a well-conceived chart can make your numbers more understandable. Because a chart presents a picture, charts are particularly useful for summarizing a series of numbers and their interrelationships.
-
Column: Column chart shows data changes over a period of time or illustrates comparisons among items.
-
Bar: A bar chart illustrates comparisons among individual items.
-
Pie: A pie chart shows the size of items that make up a data series, proportional to the sum of the items. It always shows only one data series and is useful when you want to emphasize a significant element in the data.
-
Line: A line chart shows trends in data at equal intervals.
-
Area: An area chart emphasizes the magnitude of change over time.
-
X Y Scatter: An xy (scatter) chart shows the relationships among the numeric values in several data series, or plots two groups of numbers as one series of xy coordinates.
-
Stock: This chart type is most often used for stock price data, but can also be used for scientific data (for example, to indicate temperature changes).
-
Surface: A surface chart is useful when you want to find the 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.
-
Doughnut: Like a pie chart, a doughnut chart shows the relationship of parts to a whole; however, it can contain more than one data series.
-
Bubble: Data that is arranged in columns on a worksheet, so that x values are listed in the first column and corresponding y values and bubble size values are listed in adjacent columns, can be plotted in a bubble chart.
-
Radar: A radar chart compares the aggregate values of a number of data series.
