There are two ways you can add the Trend control to an InTouch window: using the ActiveX Controls wizard, or by adding a Graphic object containing the Trend control to your window.

In both cases, you can edit the properties of the control at runtime with scripting.

If you use the Trend control embedded within a graphic object, you can set the default properties of the control within the IDE with no scripting required.

To add the aaHistClientTrend control using the wizard

  1. In WindowMaker, select the Wizards button. The Wizard Selection dialog box appears.

  2. Select the aaHistClientTrend control.

  3. Click OK.

    The control appears in the window.

To add the Trend control using a graphic object

  1. In WindowMaker, create a new graphic, then open it for editing.

  2. Select Trend Control Trend Control button from the Toolbox, then click on the graphic to add the control.

  3. Save and close the new graphic.

  4. Drag the new graphic from the toolbox onto the canvas.

    The control appears in the window.

  5. To change the initial properties of the Trend control, right-click the control and select Properties... to display the Trend properties window. Select the Properties tab and set the starting property values as required.

    For more information about working with InTouch, refer to the System Platform documentation.
