The array property CrossHair defines the form and layout of the four available crosshairs. The parameter chIdx may assume a value from 1 to 4, values beyond this range are contrained to the nearest of the two borders (for example, assigning a value of 7 to chIdx will be in effect the assignment of a value of 4). The CrossHair property supports the following sub-properties:
| PosX: double; |
Position on x-axis. |
| PosY: double; |
Position on y-axis. |
| Color: TColor; |
Color of crosshair. |
| Layer: integer; |
Assigns a crosshair to a layer. By default, the crosshairs 1 to 4 are assigned to the chart layers 1 to 4. |
| Mode: TCrossHMode; |
Defines the layout of the crosshair:
chOff... crosshair is switched off
chHoriz... horizontal line
chVert... vertical line
chBoth... full crosshair
chCrossBox... small crosshair
chBox... square box
|
| LineType: TPenStyle; |
Defines the pen style for the crosshair. LineType may assume one of the following values:
psSolid (solid line)
psDot (dotted line)
psDash (dashed line)
psDashDot (dash-dot combinations)
psDashDotDot (series of dash-dot-dot combinations)
Note that the LineType will be effective only if LineWid is set to 1 |
| LineWid: integer; |
Defines the line width of the crosshair. Note that lines broader than 1 will always be drawn as solid line, even if LineType is set to some other value. |
| Hint 1: |
Please note that the visible crosshairs can be dragged by using the mouse if the property MouseAction is set to maDragCrossH. |
