Child Set Tags Understanding the Graph Tags

Using ADF Graph Components 24-11 graph, you must set the funnelPercentMeasure property on the graph to be True. This setting should be done in the XML for the graph. ■ Funnel graphs require at least one group of data to be used as a stage.

24.3.6 Line Graph Data Requirements

A line graph represents data as a line, as a series of data points, or as data points that are connected by a line. The following kinds of line graphs are available: ■ Absolute: Each line segment connects two data points. This kind of graph can have its axes arranged as single y-axis, dual y-axis, and split dual y-axis. ■ Stacked: Lines for each set of data are appended to previous sets of data. The size of the stack represents a cumulative data total. This kind of graph can have its axes arranged as single y-axis, dual y-axis, and split dual y-axis. ■ Percentage: Lines are stacked and each line shows the percentage of a given set of data relative to the cumulative total of all sets of data. Percentage line graphs are arranged only with a single y-axis. Data guidelines for line graphs are: ■ Line graphs require at least two groups of data because lines require at least two points. A group is represented by a marker of each color. The group has a tick label such as the name of a month. ■ Percentage line graphs cannot have negative numbers. ■ Dual-Y graphs require two sets of data.

24.3.7 Pareto Graph Data Requirements

Pareto graphs are specifically designed for identifying sources of defects. In a Pareto graph, a series of bars identifies different sources of defects. These bars are arranged by value, from the greatest number to the lowest number. A line shows the percentage of the cumulative values of the bars to the total values of all the bars in the graph. The line always ends at 100. Pareto graphs are always dual-Y graphs. The y1-axis corresponds to values that the bars represent. The y2-axis corresponds to the cumulative percentage values. Data guidelines for Pareto graphs are: ■ Pareto graphs require at least two groups of data. ■ Pareto graphs cannot have negative numbers. ■ If you pass more than one set of data to a Pareto graph, the graph uses only the first set of data. ■ Do not pass percentage values as part of the data for a Pareto graph. The graph calculates the percentages based on the data that you pass.

24.3.8 Pie Graph Data Requirements

A pie graph represents data as sections of one or more circles, making the circles look like sliced pies. The following varieties of pie graphs are available: ■ Pie: The center of each circle is full. Pie graphs can consist of a single pie or multiple pies. 24-12 Web User Interface Developers Guide for Oracle Application Development Framework ■ Ring: The center of each circle has a hole in which the total pie value is displayed. Ring graphs can consist of a single ring or multiple rings. The data structure of a pie graph follows: ■ Each pie or ring represents one group of data and has a pie or ring label such as the name of a month. If you have only one group of data, then only one pie or ring appears even if you selected a multiple pie or ring graph type. Also, if any group has all zero data, then the pie or ring for that group is not displayed. ■ A series or set of data is represented by all the slices of the same color. You see legend text for each set of this data. For example, if there is a separate set of data for each country, then the name of each country appears in the legend text. Data guidelines for pie graphs are: ■ Pie graphs cannot have negative numbers. ■ Multiple pie graphs require at least two groups of data.

24.3.9 Polar Graph Data Requirements

A polar graph is a circular scatter graph. In a polar graph, as in a scatter graph, data is represented by the location of data markers. In a polar graph, the plot area, where the markers appear, is circular. For information about scatter graphs, see Section 24.3.11, Scatter Graph Data Requirements. Like scatter graphs, polar graphs are especially useful when you want to see general relationships among a number of data items. Use polar graphs rather than scatter graphs when the data has a directional aspect. Each data marker in a polar graph represents two data values: ■ The first data value is the X value. It determines the location of the marker along the x-axis, which is the location around the circle, clockwise. ■ The second data value is the Y value. It determines the location of the marker along the y-axis, which is the distance from the center of the graph. Data guidelines for a polar graph require at least two data values for each marker.

24.3.10 Radar Graph Data Requirements

A radar graph is a polygonal line graph similar to how a polar graph is a circular scatter graph. Use radar graphs to show patterns that occur in cycles, such as monthly sales for the last three years. The data structure of a radar graph follows: ■ The number of sides on the polygon is equal to the number of groups of data. Each corner of the polygon represents a group. ■ A series or set of data is represented by a line, all the markers of the same color, or both. It is labeled by legend text. Data guidelines for radar graphs require at least three groups of data.

24.3.11 Scatter Graph Data Requirements

A scatter graph represents data by the location of data markers. Scatter graphs are especially useful when you want to see general relationships among a number of data points. For example, you can use a scatter graph to examine the relationships between Sales and Profit values for specific products.
