constants ZoomOnFlyEnum
The ZoomOnFlyEnum type indicates the flags that can be combined to show the control's Zoom-OnFly view. The Zoom-OnFly view was provided to let you magnify a portion of the chart without affecting the chart's scale. The Zoom-OnFly view displays the item and its neighbors from the cursor, and additional information about the bar from the cursor.  The Chart.AllowZoomOnFly property indicates whether the Zoom-OnFly view is shown once the user presses the CTRL or SHIFT key over a bar. The ZoomOnFlyEnum type supports the following values:

NameValueDescription
exNoZoomOnFly0 (Default) The Zoom-OnFly view is not available.
exZoomOnFlyShift1 If this flag is present, the Zoom-OnFly view can be shown if pressing the SHIFT, not requiring the CTRL + SHIFT keys combination.
exZoomOnFlyCtrl2 If this flag is present, the Zoom-OnFly view can be shown if pressing the CTRL, not requiring the CTRL + SHIFT keys combination.
exAllowRefineOnFly8 Specifies whether the Zoom-OnFly view is visible when the user clicks the mouse. 
exAllowInfoOnFly16 Specifies whether the Zoom-OnFly view is visible when the user hovers the mouse.
exZoomOnFlyBarsOnly32 Specifies whether the Zoom-OnFly view is visible if the cursor hovers a bar, and show nothing, if there is no bar at the cursor position.
exZoomOnFly24 Specifies that the Zoom-OnFly view is visible when the user clicks or hovers the mouse on the chart area, while pressing the CTRL + SHIFT keys combination. For instance, if the Chart.AllowZoomOnFly property is exZoomOnFly + exZoomOnFlyShift ( 25 ), the view can be shown if the user presses the SHIFT, not requiring the CTRL + SHIFT keys combination.
exZoomOnFlyIncludeNeighborItems256 Specifies whether the Zoom-OnFly view displays the neighbors items ( previously visible item and next visible items ). For instance, if the Chart.AllowZoomOnFly property is exZoomOnFly + exZoomOnFlyIncludeNeighborItems ( 280 ), the view shows the previously and next visible item of the one from the cursor. In other words, the view can show up to 3 items including the item from the cursor, the previously visible item and the next visible items. The last two are shown only if they exists. Use this option to display more than one item in the view for better alignment of the bars based on their neighbors.
exZoomOnFlyIncludeSelectedItems768 Indicates that the view can show the item from the cursor, including the previously selected item and the next selected item. You can use this flag to show the current item among with any other selected item.  Use exZoomOnFly + exZoomOnFlyIncludeSelectedItems ( 793 ) option to include the next and previously selected items for a better comparing between selection and the item from the cursor. For instance, click or selects an item to be compared and next go to other item, and so the view will include these items. Use the SelectOnClick property to prevent selecting a row / item when clicking the chart portion of the control.
