24.3.3 Bubble Graph Data Requirements

A bubble graph is one in which data is represented by the location and size of round data markers bubbles. Each data marker in a bubble graph represents three group values: ■ The first data value is the X value. It determines the marker’s location along the x-axis. ■ The second data value is the Y value. It determines the marker’s location along the y-axis. ■ The third data value is the z value. It determines the size of the marker. The following kinds of bubble graphs are available: Bubble graph with a single y-axis and bubble graph with a dual y-axis. Data guidelines for a bubble graph are: ■ Bubble graphs require at least three data values for a data marker. ■ For more than one group of data, bubble graphs require that data must be in multiples of three. For example, in a specific bubble graph, you might need three values for Paris, three for Tokyo, and so on. An example of these three values might be: X value is average life expectancy, Y value is average income, and z value is population.

24.3.4 Combination Graph Data Requirements

A combination graph uses different types of data markers to display different sets of data. The data markers used are bar, area, and line. Data guidelines for combination graphs are: ■ Combination graphs require at least two sets of data or else the graph cannot show different marker types. ■ Combination graphs require at least two groups of data or else the graph cannot render an area marker or a line marker.

24.3.5 Funnel Graph Data Requirements

A funnel graph is a visual representation of data related to steps in a process. As the value for a given step or slice of the funnel approaches the quota for that slice, the slice fills. A funnel renders a three-dimensional chart that represents target and actual values, and levels by color. A funnel graph displays data where the target is considered to be 100. Therefore, if the actual value is 50 and target is 200, then 25 of the slice will be filled. Data guidelines for funnel graphs are: ■ Funnel graphs require two series or sets of data. These two sets of data serve as the target and actual data values. Threshold values appear in the graph legend. Another variation of the funnel graph requires only one set of data, where the data values shown are percentages of the total values. To produce this type of funnel Note: When you look at a bubble graph, you can identify groups of data by examining tooltips on the markers. However, identifying groups is not as important as looking more at the overall pattern of the data markers. 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.
