  1. 1. Module No. -5 Components of an Excel Chart: An Excel-chart comprises of many components as shown in following figure. Chart Area Data Point/Marker Sales Performance Chart 300 Data Label Grid Lines Sales Value in Lacks 300 Plot Area Y Axis Title Y Axis Y Axis Values 250 200 150 150 Chart Title 150 Tek Sun 100 100 Legend 200 50 50 0 X Axis Jan Feb Mar Month X Axis Title The figure shows that an Excel-chart comprises of two areas i.e. Chart area and the Plot area. Chart area : Chart area is the entire area that is reserved for accommodating the chart and other components such as legends, titles etc. Plot area : Plot area is a part of chart area, which contains the chart. Y axis : It is the vertical line whose length and segments represent different values. The y-axis is used to show the variation of different identities. X axis : A horizontal line on which you show the variation of another component of the chart. It's length and segments represent different intervals of the values. Y axis title : Y- axis title identifies the values that have been shown on Y- axis. X axis title : X- axis conveys the full details of the X-axis values. Grid lines : Grid lines are the lines that can be thought of as an extension of tick marks. They help in reading the values of the data points. They are scaled according to the values of the axes.
  2. 2. Data Series : Data series is a collection of related values that are plotted on a chart. For example, following are two data series : A 1 2 3 Sales Expenditure B Jan 100 150 C Feb 50 1000 D Mar 150 200 Data Point : It represents one value of the data series. Data label : Data label is some piece of text, which is written near data point to highlight some aspect of it. Chart title : Chart title is the text written in chart area, which identifies the chart. Legends : Legends are some sort of labels that identify different series that have been plotted in the chart. Generally, these labels are attached to a symbol or color or pattern that is associated with the series of the chart. It is used to distinguish one data series from another. Creating charts in Excel: Excel chart is a graphical representation of Excel worksheet data. To represent the data in the form of charts, first prepare the worksheet and then select the portion of the worksheet that is to be represented in the form of chart.

Wizard is a series of predefined sequence of steps, which are specially designed to accomplish a task. Each step of Wizard provides you with necessary help, guidelines and lot of options to choose from. Wizard displays a dialog box. Each dialog box has a Forward, Backward buttons to move to the next or previous step respectively.
