TdxChartRange.VisibleMin Property

Specifies the minimum visible series value or argument within the currently available diagram area, depending on the current axis.

Declaration

property VisibleMin: Variant read; write;

Property Value

Type	Description
Variant	The minimum visible series value or argument within the currently available diagram area, depending on the current axis.

Remarks

Range.VisibleMin and Range.VisibleMax properties of the axis of arguments (X-Axis) and the axis of values (Y-Axis) specify the minimum and maximum currently visible arguments and values. If Range.VisibleMin and Range.VisibleMax properties are unspecified, the visible diagram area corresponds to the zoom factor of 100%.

Examples: Resize the Visible Diagram Area

You can use Range.VisibleMin and Range.VisibleMax properties to reduce the range of the currently visible axis scale, that is, zoom the diagram along the current axis.

The Axis of Arguments

VisibleMin	VisibleMax	Example[1]
Unspecified (equivalent to -4)[2]	Unspecified (equivalent to 6)[3]
-1[4]	3[4]

The Axis of Values

VisibleMin	VisibleMax	Example[5]
Unspecified (equivalent to -5)[2]	Unspecified (equivalent to 6)[3]
-3[6]	4[6]

Default Value and Limitations

The VisibleMin property has no default value. If the VisibleMin property is unspecified, the minimum visible value is the difference between WholeMin and ActualSideMarginMin property values.

The VisibleMin property value cannot be less than the difference between WholeMin and ActualSideMarginMin property values.

Footnotes

1. This example demonstrates different VisibleMin and VisibleMax property values for the axis of arguments of the same XY diagram under the following conditions:

   • WholeMin and WholeMax properties are set to -3 and 5, respectively.
   • The AutoSideMargins property is set to False.
   • SideMarginMin and SideMarginMax properties are set to 1.

2. The unspecified VisibleMin property defines the minimum visible value as the difference between WholeMin and ActualSideMarginMin property values.

3. The unspecified VisibleMax property defines the maximum visible value as the sum of WholeMax and ActualSideMarginMax property values.

4. The visible portion of the scale on the axis of arguments is less than the available scale range along the axis of arguments. The XY diagram is zoomed in and centered along the axis of arguments.

5. This example demonstrates different VisibleMin and VisibleMax property values for the axis of values of the same XY diagram under the following conditions:

   • WholeMin and WholeMax properties are set to -4 and 5, respectively.
   • The AutoSideMargins property is set to False.
   • SideMarginMin and SideMarginMax properties are set to 1.

6. The visible portion of the scale on the axis of arguments is less than the available scale range along the axis of values. The XY diagram is zoomed in and centered along the axis of values.
