Charts are graphical representations of numerical data. Choose from the following chart types: Bar, Line, Combo, Radar, Scatter, Grid, Pie, Funnel, Block and Gauge Chart as well as Pivot Table and Straight Table. It is possible to switch between different representations of an existing chart, by changing the Chart Type in the Chart Properties: General page.
A brief introduction to chart types:
|Bar Chart||This is the most basic chart type. Each x-axis value corresponds to a bar. The bar height corresponds to its numerical y-axis value.|
The line chart is essentially defined in the same way as the bar chart. Instead of using bars the data can be presented as lines between value points, as value points only or as both lines and value points.
|Combo Chart||The combo chart allows the combination of the features of the bar chart with those of the line chart. One expression will be displayed by lines and/or symbols, the other as bars.|
|Radar Chart||The radar chart is a variant of the line chart where the x-axis is plotted in a circle around the chart, resulting in a projection reminiscent of a radar screen or a spider's web.|
|Scatter Chart||The scatter chart plots data points representing combinations of expressions, iterated over one or several dimensions. Both axes are continuous, representing one expression each.|
|Grid Chart||The grid chart is a variant of the scatter chart that plots dimension values on the axes and uses an expression to determine the plot symbol. It can also show a third dimension in the form of small pie charts as plot symbols.|
|Pie Chart||Shows the relation between single fields (primary dimension) and a single expression. A variant chart type is drawn when a secondary dimension is introduced. If more expressions than one are enabled in the Chart properties: Expressions page, the first in the expression list will be displayed. To switch expression use the Promote/Demote buttons in the Expressions property page.|
|Block Chart||The block chart shows the relation between expression values as blocks of varying area. It uses a single expression and up to three dimensions, with each dimension block further divided into sub-blocks. The total area of the block chart always equals 100% of the possible expression values. Sometimes a color function is used for creating a so called "heat chart".|
|Funnel Chart||The funnel chart is typically used for showing data in flows and processes. From a display standpoint it is related to the pie chart. The chart may be shown with either segment height/width or segment area proportional to data. It is also possible to draw the chart with equal segment heights/widths without regards to data points.|
|Gauge Chart||Gauge charts are used to display the value of a single expression, lacking dimensions.|
|Mekko Chart||Mekko charts present data using variable width bars. They can display up to three levels of data in a two-dimensional chart. Mekko charts are useful in such areas as market analysis.|
|Pivot Table||The pivot table presents dimensions and expressions
in table form. There is no formal limit to the number of dimensions or
A pivot table can be defined without expressions, generating a tree view for navigating the dimension levels.
|Straight Table||The straight table differs from the pivot table in that it can not display subtotals and that the grouping of dimensions is shown in record form so that each row of the table contains field and expression values.|
