Description

All data at once

Click this radio button to load all data immediately.

Data on demand

Click this radio button to load data on demand only. If this option is selected you need to specify what parameters will be used to control the on-demand loading.

Define input for parameters that should control loading

This is where you select what will affect the loading of data from the perspective of the on-demand data table. All columns and parameters available in the selected information link or connection data table are listed. Click to select the parameter in the list and click Define Input... to specify a condition that must be fulfilled for any data to be loaded.

Any required prompts or parameters that were specified upon the creation of an information link will be listed as Required parameters in this field. This means that you must specify input handling of these parameters to be able to load any on-demand data at all.

Define Input...

Opens the Define Input dialog where you can specify how the selected parameter will be connected to the on-demand data.

Clear Input

Removes the previously added input from the selected parameter.

Load automatically

Select this check box if the on-demand data should be loaded automatically each time the specified input conditions are changed. If the check box is cleared the visualization can be manually updated using the refresh icon, vis_refresh_i.png, in the visualization title bar.

A data table set to load automatically will switch to manual update if cyclic dependencies are detected in the analysis.

Allow caching

Select this check box to allow caching of data. This may speed up the process when loading new subsets of data. However, if the underlying data is updated during the current TIBCO Spotfire session you may end up with different results for a specific set of input values depending on whether or not the current selection is stored in the cache. You should always clear the check box if you know that the underlying data may be updated during your current session.
