The Visualization Selector
The Visualization Selector lets you switch between Ad Hoc view types, allowing you to choose the best way to represent your information in the Ad Hoc view, including:
•  Table, which displays values corresponding to the rows and columns in the data source. 
•  Crosstab, which compares one or more values across multiple sets of related fields. 
•  Column, which compares values displayed as columns. 
•  Bar, which compares values displayed as bars. 
•  Line, which compares values displayed as points connected by lines. 
•  Area, which compares values displayed as shaded areas. 
•  Spider, which compares three or more values on a series of spokes. Spider charts can use columns, lines, or areas to display values. 
•  Dual and MultiAxis, which display values using two or more measures. 
•  Time Series, which compares time intervals displayed as points connected by lines. The Time Series chart type is only available for nonOLAP charts. 
•  Scatter, which compares values as individual points arrayed across both axes of a chart. 
•  Bubble, which compares three measures displayed as circles of varying sizes arrayed across both axes of a chart. 
•  Pie, which compares values displayed as slices of a circular graph. 
•  Range, which displays values as heat and tree maps. Only the Heat Map chart is available for OLAP data sources. 
•  Gauges, which displays values as a radial or arc gauge, based on a defined minimum and maximum measure setting. 

JasperReports Server has limited support for scatter charts created in some older versions. You can use the Ad Hoc views for those scatter charts to generate new reports, but you can't edit them. 
To select a new visualization type:
1.  In the Ad Hoc Editor tool bar, click the icon to display the Select Visualization Type window. 

Select Visualization Type Window 
2.  Click the type of visualization you want to apply to your report. The selected visualization type is outlined in blue. The Visualization Selector displays a description of the selected visualization and the number of fields and measures it uses. 
3.  Click Apply and Close to use the visualization type. 
The following table describes the available visualization types, and rules (if any) affecting their use:

Description 


Data Grid 
Data grids display values from the data source in columns and rows as either individual or aggregate values.  
Crosstab. Compares one or more measures across multiple sets of related fields.  
Table. Displays values corresponding to the columns and rows in the data source. 

Column and Bar 
Column charts compare values displayed as columns and bars.  

Column. Multiple measures of a group are depicted as individual columns. 


Stacked Column. Multiple measures of a group are depicted as portions of a single column whose size reflects the aggregate value of the group. 


Percent Column. Multiple measures of a group are depicted as portions of a single column of fixed size. 


Spider Column. Multiple measures of a group are depicted as portions of individual "columns" along a spoked chart. 


Bar. Multiple measures of a group are depicted as individual bars. 


Stacked Bar. Multiple measures of a group are depicted as portions of a single bar whose size reflects the aggregate value of the group. 


Percent Bar. Multiple measures of a group are depicted as portions of a single bar of fixed size. 

Line and Area 
Line charts compare values displayed as points connected by lines.  

Line. Displays data points connected with straight lines. 


Spline. Displays data points connected with a fitted curve. 


Spider Line. Displays data points connected with straight lines on a spoked chart. 


Area. Displays data points connected with a straight line and a color below the line; groups are displayed as transparent overlays. 


Stacked Area. Displays data points connected with a straight line and a solid color below the line; groups are displayed as solid areas arranged vertically, one on top of another. 


Percent Area. Displays data points connected with a straight line and a solid color below the line; groups are displayed as portions of an area of fixed sized, and arranged vertically one on top of the another. 


Area Spline. Displays data points connected with a fitted curve and a color below the line; groups are displayed as transparent overlays. 


Spider Area. Displays data points connected with straight lines and a solid color between the line and the center of a spoked chart; groups are displayed as transparent overlays. 

Dual and MultiAxis 
Dual and multiaxis charts compare two or more measures, using multiple charting types or multiple axes.  

Column Line. Displays leftmost measures as columns, last measure as a line.



Stacked Column Line. Displays leftmost measures as stacked bars, last measure as a line.



Column Spline. Displays leftmost measures as columns, last measure as a spline.



Stacked Column Spline. Displays leftmost measures as stacked columns, last measure as a line.



MultiAxis Line. Displays each measure as a separate axis line.



MultiAxis Spline. Displays each measure as a separate axis spline.



MultiAxis Column. Displays each measure as a separate axis column.


Time Series 
Time Series charts illustrate data points at successive time intervals.  

Line. Displays date and time data points connected with straight lines.



Spline. Displays date and time data points connected with a fitted curve.



Area. Displays date and time data points connected with a straight line and a color below the line; groups are displayed as transparent overlays.



Area Spline. Displays date and time data points connected with a fitted curve and a color below the line; groups are displayed as transparent overlays.


Scatter 
Shows the correlation between two or three measures.  

Scatter. Displays first measure as the xaxis, the second measure as the yaxis. Other fields and dimensions in the column group become data points.


Bubble. Displays first measure as the xaxis, the second measure as the yaxis, and the third measure determines the size of the disk.


Pie 
Pie charts display values as slices of a circular graph. 


Pie. Multiple measures of a group are displayed as sectors of a circle. 


Dual Pie. Multiple measures of a group are displayed as sectors of concentric circles.


SemiPie. Multiple measures of a group are displayed as sectors of a halfcircle.  
Range 
Range charts display values as heat maps. 

Heat Map. Individual values represented as colors. NonOLAP:
OLAP:


Time Series Heat Map. Individual values across dates/times represented as colors.


Dual Measure Tree Map. Displays data as colorcoded rectangles; the size of each rectangle is proportional to the first measure and the color represents the second measure.


Tree Map. Displays data as rectangles; the size of each rectangle is proportional to the measure of the data it represents. The tree map displays nested rectangles when you have more than one field; the parent rectangle represents the leftmost measure while the nested rectangles represent the current level of aggregation. Click on a parent rectangle to drill down to the nest rectangles.


Parent Tree Map. Displays data as nested rectangles; the size of each rectangle is proportional to the measure of the data it represents. The nested rectangles represent the current level of aggregation while the larger rectangle represents the parent level in the hierarchy. Click on a parent rectangle to drill down to the nest rectangles.


Gauges 
Gauges display values as a portion of a radial or arc gauge. 

Gauge. Displays a single data value as a portion of a circle; the length of the circle is the data's numeric value proportional to the maximum size defined for the measure.


Multilevel Gauge. Displays one or more data values as concentric circles; each circle represents a measure and the length of the circle is the data's numeric value proportional to the maximum size defined for the measures.


Arc Gauge. Displays a single data value as a portion of a semicircular arc; the length of the arc is the data's value proportional to the maximum size defined for the measure.
