TdxChartEmptyPointsDisplayMode Enum

Enumerates available empty series point display modes.

#Declaration

Delphi
TdxChartEmptyPointsDisplayMode = (
    Default,
    Zero,
    Gap
);

#Members

Name Description
Default

Default. The default empty point display mode corresponds to the Gap option.

Zero

The Chart control interprets a Null value in the bound dataset or a Null Variant value in a series point collection in unbound mode as a zero value.

Gap

The Chart control interprets a Null value in the bound dataset or a Null Variant value in a series point collection in unbound mode as a gap between series points rather than a point.

#Remarks

Different empty point display modes allow you to change how a Chart control interprets Null (in the bound dataset) and Null Variant (in a series point collection) values.

Note

TdxChartEmptyPointsDisplayMode is a scoped enumeration type. Use the type name together with a scope resolution token (. in Delphi or :: in C++Builder) followed by an enumeration value to refer to this value. For example, use TdxChartEmptyPointsDisplayMode.Zero (in Delphi) or TdxChartEmptyPointsDisplayMode::Zero (in C++Builder) to refer to the Zero value in code.

#Direct TdxChartEmptyPointsDisplayMode Type References

The EmptyPointsDisplayMode property of XY and simple series classes references the TdxChartEmptyPointsDisplayMode type.
