Working with Chart

 

One of the most important features of spreadsheet is the ability to create charts based on numeric data. The charts are used to present data in an easy manner.

Chart wizard dialog box has 4 steps viz. (1) Chart type (2) Data Range (3) Data Series and (4) Chart Elements. The “Next” button is used to move from one step to another step.

 

Step 1: Chart type

 

The first step of “Chart wizard” is used to select Chart type. All available chart types are listed under the “Choose a chart type” list box. On the right side of the list box shows style of the selected chart; each chart type has different styles.


For example, Column chart has three styles viz. Normal, Stacked and Percent Stacked. Refer Figure 7.49

 

"3D Look" check box helps to display the selected chart type in an attractive form. 3D Look is applied only for Column, Bar, Pie and Area chart type. Refer Figure 7.50.

If the user had selected the data before invoking "chart wizard", the selected range will appear automatically in the textbox as shown in Figure 7.51.

 

There are two checkboxes used to set the first row or first column or both, as X and Y axis labels to the chart.
