Editing charting scheme property mappings

In the Edit Charting Schemes window, each charting scheme in the navigation tree contains a list of the entity and link types that the schema defines. To map from a schema property type to a property of an Analyst's Notebook chart item, you add an entry for the chart item property to the list in the relevant entity or link type.

For example, to control the label of an Analyst's Notebook chart item that contains an i2 Analyze entity record of type Person, you add the Label chart item property to the Properties list for the Person entity type. You can also edit the Default entity (or link) type to control how chart item properties are populated when the charting scheme doesn't contain configuration for a particular type.

Before you begin

The full list of chart item properties that you can populate through the mappings in a charting scheme is as follows:

  • Label

  • Date

  • Time

  • Description of date & time

  • Description

  • Source reference

  • Source type

When you edit the mapping for a chart item property, you create an ordered list of schema property types and other sources whose values are eventually combined to form the chart item property value. You also have the option to add a prefix or a suffix (often a space or some other punctuation) to the value from each source in the list.

The label for an entity or link type that you defined in the labeling scheme is available for use in all chart item properties for that type in the charting scheme, but it's typical to use it specifically for the Label property.

Default labels for links

A common application for a charting scheme is to provide a label that uses some fixed text for chart links, when those links contain i2 Analyze records for which the charting scheme has no explicit label configuration.

Dates and times for timeline analysis

The Date and Time chart item properties are essential to creating and using timeline charts in Analyst's Notebook. To participate in a timeline chart, a chart item must have values for its Date and Time properties. You can provide those values by use a charting scheme to map the values of i2 Analyze record properties to them.

Procedure

To map a schema property type to a chart item property:

  1. In Schema Designer, open the i2 Analyze schema whose charting schemes you want to edit.

  2. From the application window, click File > Edit Charting Schemes to open the Edit Charting Schemes window.

  3. Expand the charting scheme that you want to edit, and then find the entity or link type from the schema that you want to create a mapping for. (Alternatively, select the Default type in either category.)

  4. Right-click the Properties entry under your selected entity or link type, and then click Insert Chart Item Property Type.

    The Add Chart Item Property Type dialog appears.

  5. From the list in the dialog, select the chart item property that you want to map to and click OK. The list of available properties gets shorter as you add more mappings.

    Schema Designer displays a list of the sources whose values will populate the chart item property. For a new mapping, the list starts empty. You can use the Insert button to add sources to the list.

  6. Add sources to the list, and if necessary put them in the order that you want them to appear in chart item property values.

  7. Click OK to confirm your changes, save the schema, and then redeploy it to the i2 Analyze server.

Results

When the mapping is complete, the items on an Analyst's Notebook chart that uses this charting scheme will have their properties populated from data in the i2 Analyze records that they contain.
