Where possible, a configured report is displayed in graphical format in the Chart window. You can create a chart for any report that contains no more than one dimension. Multidimensional charts are not currently supported.
Notes
 By default, Hour of Day is the default Xaxis.
 Long chart labels can be truncated. You can change labels in the Options screen.
Event Data in Charts
This table describes the event data in charts:
Event data  Description 

Zero filling  Zerofilling is used to prevent reporting gaps. Report data can be reported as a set of
zeros (0 ) if a timebased dimension is added to the report and data is not
available for some displayed time segments. For null dimension values that are zerofilled, two
dashes ( ) are inserted in the report. Counts of these values are reported as
0 
Events and timestamps  Hits are evaluated against the set of current set of events at the time of evaluation. If hits are spooled or otherwise not processed immediately, there can be effects in reporting if changes are made to eventrelated objects in the interim. A message is reported in the Portal. 
Summary calculations  Total and average values are calculated only if the event is configured to display count or
sum data. These summary calculations are not available for other event data types or added functions
(for example, same day average). The displayed calculations are based on the data available in the
detail table, which reflects the currently displayed report.

Effect of Xaxis dimensions
By default, labels for dimensions on each axis are empty. For display purposes, chart labels for lengthy dimensional values can be trimmed.
Charts
 Bar Graphs
 Each first xaxis dimension value becomes a major unit on the xaxis. On charts, no second xaxis dimension is permitted.
 Each event gets a bar within the minor unit.
 The height of the bar is the count, sum, and so on.
 Line/Shaded Area Graphs  Each dimension segment of each event gets a separate line.
 Pie  You cannot have Xaxis dimensions on a pie graph.
Tables
 The first Xaxis dimension becomes the first column. Each dimension value gets a row.
 The second Xaxis dimension becomes the second column. Each dimension value gets a row for each dimension value in the first Xaxis dimension.
 The Yaxis dimension is listed next.
 Each event gets a column. Events are listed in the order in which they are added to the report.
 Each row must have the total value for that dimension combination.
 The first row must be the total value for all the dimensional values.
Example
For example, you have a Price event that is stored like this in the DB:
Member Type  Credit Card  Product  Price 

Bronze  Amex  Plane  72 
Bronze  Disc  Plane  63 
Gold  Amex  Car  24 
Gold  Visa  Boat  73 
Gold  Visa  Car  32 
Silver  Amex  Boat  43 
If you add events to the report, set the Data Count to be Sum, and make Member Type and Credit Card the Xaxis dimensions, the table then looks like:
Member Type  Credit Card  Price 

Bronze  Amex  72 
Bronze  Disc  63 
Gold  Amex  24 
Gold  Visa  105 
Silver  Amex  43 
There are only 2 Gold rows where there were 3 in the database. This is because the 2 Gold+Visa rows in the DB get combined (73+32=105) since there is no longer the Product type to differentiate them.
Now let us say you have another event that tracks the Insurance. It looks like the following.
Member Type  Credit Card  Product  Insurance 

Bronze  Amex  Plane  25 
Bronze  Visa  Car  15 
Gold  Amex  Car  15 
Gold  Disc  Boat  20 
Gold  Visa  Plane  25 
Silver  Visa  Car  15 
If you add this event to the report, you would get this table:
Member Type  Credit Card  Price  Insurance 

Bronze  Amex  72  25 
Bronze  Disc  63   
Bronze  Visa    15 
Gold  Amex  24  15 
Gold  Disc    20 
Gold  Visa  105  25 
Silver  Amex  43   
Silver  Visa    15 
There are more rows than what is displayed in the first scenario. This is because the Insurance event had different Credit Card values for each Member Type than the Price Event. So the report table is like the union of 2 data tables.
Effect of Yaxis dimensions
Adding a dimension to the Yaxis can be used to create a stacked data report. Multiple Yaxis dimensions are not charted.
If you add a Yaxis dimension that contains many values, do not position the chart legend to be on top, which can corrupt the display. If the report contains many items, some values can not be displayed in the Legend.
Charts
 Bar Graphs  you get stacked bars, with each element of the stack being the dimension segment.
 Line/Shaded Area Graphs  Each dimension segment gets a line.
 Pie  The dimension values make up the slices of the pie.
Tables
The Yaxis dimension values each get a column after the Xaxis dimensions.
Example
For example, assume that you set Member Type as the first Xaxis dimension, Credit Card as the second Xaxis dimension, and Product as the Yaxis dimension. You would get the following table:
Member Type  Credit Card  Boat  Car  Plane 

Bronze  Amex      72 
Bronze  Disc      63 
Gold  Amex    24   
Gold  Visa  73     
Gold  Visa    32   
Silver  Amex  43
