3. What is a chart? A chart is a visual representation of numeric data
An effective chart depicts data in a clear, easy-to-interpret fashion. It is a visual representation of numerical data that compares data and helps to reveal trends or patterns.

4. Chart components Chart components include:
Data Points Ex: Single cell E1
Data Series Ex: Range of cells E1:E11
Category Labels – Text that describes data
The chart area contains the entire chart and all of its elements. The plot area contains the graphical representation of values in the data series. The X-axis (Category axis) is a horizontal line. The Y-axis (Value axis) is a vertical line. Axes form the borders for plot area.

5. Types of charts
A column chart displays data vertically, with each data series forming a column
Here the data series is of year 2012.

6. Clustered column chart
To plot multiple data series. Each data series is depicted in a different color.
This chart illustrates four data series, one for each year. A legend is included to help the reader distinguish the multiple data series.

7. Pie Chart
This type of chart plots a single data series where each point is a sector with area proportional to the total of the series. A legend is used to display the category label for each data point in a different color. Data labels, such as percentages, are often portrayed on the pie wedges. An exploded pie chart separates one or more pie slices from the rest.

17. Chart Layout
The Layout tab offers many ways to enhance a chart visually

18. Selecting and Formatting Chart Elements
Formatting a chart element:
Right-click the element and select the Format element command
The element portion will change depending on the selection (ex. Format Data Series)
The easiest method to format a chart element, such as a legend or data series, is to right-click it on the chart and select the Format element command. The element portion will change depending on the selection (for example, Format Data Series or Format Legend).
Figure above illustrates the Format Data Series dialog box with options for Fill, Border Color, and more. Alternatively, you can click the Chart Elements arrow in the Current Selections group, and select the element from the list. Once selected, click Format Selection in the Current Selections group.

19. Chart Titles and Legend
A chart title is the label that describes the entire chart
An axis title is a label that describes either the category or value axis
A legend is used to distinguish data points in a pie chart or data series in a multiple series chart
The Labels group on the Layout tab contains options to edit the chart title, axis titles, legend, data labels, and data table. Chart title options include None, Centered Overlay Title, and Above Chart. More Title Options offer fill, border, and alignment settings.
To display category axis title options, click Axis Titles in the Labels group, and point to Primary Horizontal Axis Title. Options include None, Title Below Axis, and More Primary Horizontal Axis Title Options.

21. Adding a Trendline
A trendline is a line used to depict trends and forecast future data
Example: Add an appropriate Trend Line to Series 1.
Charts help reveal trends, patterns, and other tendencies that are difficult to uncover by looking at numerical data in a worksheet. A trendline is a line used to depict trends and forecast future data, commonly used in prediction events. To add a trendline, click Treadline in the Analysis group, and select the type of trendline from Linear Trendline, Exponential Treadline, Linear Forecast Treadline, or Two Period Moving Average.
