Editing Charts 
Use
Charts display number series visually and make it easier for users to interpret business data.
Prerequisites
If you want to convert charts that you have used in SAP BW 2.x or SAP BW 3.0/3.1/3.2 to the current format, you need the standalone Internet Graphics Server (IGS) 6.40. Then you need to change to the Internet Graphics Server 7.0. For more information, see the Internet address service.sap.com/upgradeNW2004s ® Upgrade.
You can edit a chart in the Web Application Designer or in the Web Application Wizard of the Business Explorer.
Editing in the Web Application Designer
You created a new
Web item of type Chart or selected an existing Web item of type
Chart. You then clicked on the pushbutton with the three dots next to
the Special ® Edit Chart field on the Web Items tab page in the
Properties window. This called the Chart Designer (see also 
Creating Web
Applications with the BEx Web Application Designer).
You can also open the Chart Designer by
· Double-clicking on the Web item
· Choosing Edit Chart in the context menu for the Web item
Editing in the Web Application Wizard

Process Flow
...
1. Before you begin publishing a chart you should define which chart type you want to display. You can find out how the data provider should be built based on the class of the chart type.
2. Select an existing query or formulate a new query with which the suitable view on the data can be created. This is the suitable data provider.
3. Start the publishing process and create a new Web item of type Chart.
4. It is normally advisable to configure the properties of the Web item Chart as follows:
¡ Expanded hierarchy nodes should be hidden.
¡ Totals should be suppressed.
¡ If you want to swap the data providers in the chart, you should assign the Swap Axes for Display property to the chart. The columns and rows are then swapped automatically when the chart is generated. You need not change the view on which the chart is based.
5. When you edit the chart, the Web Application Designer or Web Application Wizard first shows the default setting, that is, a column chart.
¡ Firstly, format the chart using the wizard so that the most important settings and the number of displayed data series and data points correspond to your data provider (see also Formatting a Chart Using the Wizard). Assign the chart the required chart type and format the chart as you like.
¡ You see all chart elements that can be formatted in the list of properties in the right-hand part of the screen. You can modify the properties in line with your wishes here.
