CCNC/CCNC Module 6/Inserting Graphics/Subsection 6 Inserting Charts

Introduction
A chart is a type of information/data graphic or graphic organizer that represents tabular numeric data and/or functions. Charts are often used to visually represent large quantities of data and the relationship between different parts of the data for ease of understanding. Charts can usually be read more quickly than the raw data that they come from. Charts add visual interest and useful information represented by lines, bars, pie slices, or other markers.

Inserting a Simple Table
In this tutorial, we are going to add attendance by gender for our monthly courses. We will insert the following table of half year training statistics on a slide.


 * In the Layouts pane, click the title, spreadsheet layout.



Type the title of the slide




 * In the Text box, double-click the icon




 * In the spreadsheet window that pops up, enter the data in the table above




 * Double-click on the spreadsheet to get back to the slide


 * Resize the table so that it fits the whole slide as shown below



Understanding the Different Chart Types
Impress allows you to create many different kinds of charts to visually accent data.

Area Chart An area chart emphasizes the trend of each value over time. An area chart also shows the relationship of parts to a whole.



Column Chart

A column chart uses vertical bars or columns to display values over different categories. This chart shows variation in value over time.



Bar Chart

A bar chart is similar to a column chart except these use horizontal instead of vertical bars. Like the column chart, the bar chart shows variation in value over time.



Line Chart

A line chart shows trends and variations in data over time. A line chart displays a series of points that are connected over time.



Pie Chart

A pie chart displays the contribution of each value to the total. Pie charts are a very effective way to display information when you want to represent different parts of the whole, or the percentages of a total.



Other Charts

Some of the other charts that you can create in Impress include XY Chart, Net chart, Stock chart, Line (3D) chart, Area (3D) chart, Bar (3D) chart, Column (3D) chart, and Pie (3D) charts.

Identifying the Parts of a Chart
Have you ever read something you didn't fully understand but when you saw that same information in a chart or graph, the concept became clear and understandable? Charts make it easy to see comparisons, patterns, and trends in the data.



Data Source

The range of cells that make up a chart. The chart is updated automatically whenever the information in these cells change.

Title

The title of the chart.

Legend

The chart key lists each color and identifies what that color represents on the chart.  Axis

The vertical and horizontal parts of a chart. The vertical axis is often referred to as the Y-axis, and the horizontal axis is referred to as the X-axis.

Data Series

The actual charted values, usually rows or columns of the source data.

Value Axis

The axis that represents the values or units of the source data.

Category Axis

The axis identifies each data series.
