Visible Property (ChartTextAppearance)

Indicates whether the chart text label is displayed.
Syntax
'Declaration
 
Public Property Visible As Boolean
public bool Visible {get; set;}
Remarks

Ensure this property has been set to True or this chart text label will not be displayed. Other reasons why chart text labels may not appear on a chart include:

This ChartTextAppearance object may not have been added to the ChartTextCollection property (named ChartText) of the correct chart control.
The values assigned to Row and Column do not identify a graphical chart element, or these identify a graphical chart element outside the current viewport (due to scaling and/or scrolling.)
Setting HorizontalAlign (often on bar charts) or VerticalAlign (often on column charts) to an inappropriate alignment. When the underlying bar or column comes into contact with a near or far axis, rendering the label could cause it to appear outside the grid (region between axes). In these cases the label will be clipped, and the appropriate alignment property should be adjusted to make the chart text label visible.
When the format string set in ItemFormatString is unrecognized or does not apply to the current chart type, a partial or empty label may render. For instance, applying the <DATA_VALUE_Z> keyword that is applicable in a bubble chart context to chart text appearing on a two-dimensional line chart (having only X and Y data values) will cause an empty string to be rendered.
A chart text label may be temporarily concealed by highlighting if the label appears inside a graphical element and the highlight is opaque.
The FontColor is the same, or close to, the background color of the chart.

Multiple ChartTextAppearance objects can apply to the same graphical chart element (identified by the same ( row, column)) and be alternated by toggling their Visible properties such that only one piece of chart text is displayed at once.
