Input+Selection+Range Details

Element Details: Input+Selection+Range

Available in: Logi Info

Source code name: InputSelection.Range

Introduced in: v11.3.049

InputSelection.Range enables the chart to be used as an input element, enabling the user to draw a rectangular region, thus selecting a pair of x and/or y axis values.

Set the max and min axis ID attributes to IDs which will be used to access users’ drawn regions. For example, to get the minimum x-value selected, set MinXaxisID=”myMinX”, then use @Request.myMinX~ to reference the selection.

Validation.Required is available so a message is displayed when the page is submitted without a chart item selected. However, the Validation's Class attribute does not apply.

These values are supported for SelectionType:

"Area" lets the user select ranges for both the X and Y axes by drawing a rectangular region.

"AreaXAxis" is the same as "Area", except the Y-axis region fills the chart. Only the X-axis is selected by the user.

"AreaYAxis" is the same as "Area", except the X-axis region fills the chart. Only the Y-axis is selected by the user.

Description

ChangeFlagElementID

UserDefined

ChangeFlagElementID helps Process Tasks know when an input value has been changed by the user. For example, a Process may only UPDATE rows when the user actually changed something, and otherwise skip the UPDATE. Set ChangeFlagElementID to the ID of an InputHidden element. Then, if the user changes this input element, the hidden element's value will become "True". You can test for this value in a Procedure.If. When using ChangeFlagElementID with an Input element that's under a DataTable, be sure to put the InputHidden element under a DataTableColumn. Process input from individual rows under a Procedure.RunDataTableRows. ChangeFlagElementID relies on the Javascript "onchange" event, so you will not be able to use your own "onchange" EventHandler with ChangeFlagElementID.

DisableClearSelection

True

False

Set to True to prevent the user from clearing the selected range. Clearing is accomplished by clicking outside the region.
