Perforce JViews Gantt Sample: Resource and Load Charts

Description

This sample shows how to use an IlvResourceDataChart to display the load for resources selected in an IlvScheduleChart.

How to Use the Sample

• At the top of the sample window, an IlvScheduleChart object shows the resources and reservations. Select a resource in the Name column and see the load for the selected resource at the bottom of the user interface. The resource load changes when you drag or delete a reservation for a resource or resources. You can make multiple selections by dragging the mouse over the table or by Ctrl/Shift-clicking resources.
• At the bottom of the sample window, an IlvResourceDataChart object displays the load for the selected resource. For a given time interval, the load of the resource is calculated by counting the number of concurrent activities that have reserved the resource. The vertical scale of the IlvResourceDataChart object indicates the number of concurrent activities. When only one resource is selected, the IlvResourceDataChart object displays the load for that resource. When multiple resources are selected, the IlvResourceDataChart object displays the cumulative load of the selected resources. The cumulative load is obtained by adding the load of each selected resource. The cumulative load is shown in a stacked manner so that you can distinguish the contribution of each individual resource by the color assigned to it.

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, resource-load-chart.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Perforce JViews.

Then, go to the installation directory of the sample and type:

ant run
