The slices are defined

Pie Chart Slices by Attribute

In Orbit GIS, an object can hold several records or attributes per attribute set. Each slice of the pie chart is defined by the (first) value of an attribute.
Use this charting technique to graphically represent the value attribute according to the other chosen attribute values per object.

Field Comment
Attribute Select an attribute for the slice using the drop-down box. Invalid attributes of data type string or boolean aren't selectable
Color Choose a fill color from the color picker window for the slice or use auto color
Label Enter a label name for the slice or use auto label

Field Comment
Add a row Create a slice
Delete a row Delete a slice
Move the selected row up Move the selected slice one up in the legend display
Move the selected row down Move the selected slice one down in the legend display
Auto Color Give all slices at once automatically a color. See Auto Color
Auto Label Give all slices at once automatically a label, the attribute name
Clear Labels Clear all labels

Pie Chart Slices by Classification

In Orbit GIS, an object can hold several records or attributes per attribute set. Each record of an attribute set of an object can have one or more values. This means that one attribute record can have several values.
Use this charting technique to graphically represent the different values of one attribute per object.

Field Comment
Classify by Select an attribute which values will be represented in a pie chart
Classification box See classification in classes

Pie Size

Field Comment
Determine by Select an attribute which value will determine the actual pie size. If no attribute was selected the radius minum value will be the fixed pie chart size.
Radius minimum Enter the minimum radius of the pie chart.
Radius maximum Enter the maximum radius of the pie chart.
The pie chart size will be interpolated between radius maximum en minimum according to the attribute value.
Size Unit Select the size unit of entered radius. See size settings

The size can be determined by an attribute value :

  • choose the attribute that must determine the actual size,
  • define a minimal and maximal size of the pie chart in pixels on screen,
  • the pie chart size will be interpolated according to the attribute value.
    (You can also use meta-attributes such as row count (amount of records for this attribute))
