# Enumeration: EmptyValueStyle

[Sheets](../modules/GC.Spread.Sheets).[Sparklines](../modules/GC.Spread.Sheets.Sparklines).EmptyValueStyle

Specifies how to show an empty value from a data series in the chart.

**`example`**
```javascript
//This example uses the EmptyValueStyle enumeration.
var data = new GC.Spread.Sheets.Range(1, 0, 8, 1);
var setting = new GC.Spread.Sheets.Sparklines.SparklineSetting
setting.options.showMarkers = true;
setting.options.lineWeight = 3;
setting.options.displayXAxis = true;
setting.options.showFirst = true;
setting.options.showLast = true;
setting.options.showLow = true;
setting.options.showHigh = true;
setting.options.showNegative = true;
setting.options.seriesColor = "Text 2 1";
setting.options.firstMarkerColor = "Text 2 3";
setting.options.negativeColor = "Accent 2 1";
setting.options.markersColor = "Accent 3 1";
setting.options.lowMarkerColor = "Accent 4 1";
setting.options.highMarkerColor = "Accent 6 1";
setting.options.lastMarkerColor = "Accent 6 6";
setting.options.axisColor = "Text 1 1";
setting.options.displayEmptyCellsAs =  GC.Spread.Sheets.Sparklines.EmptyValueStyle.Zero;
activeSheet.addSpan(13, 0, 4, 3, null);
activeSheet.setSparkline(13, 0, data, GC.Spread.Sheets.Sparklines.DataOrientation.vertical, GC.Spread.Sheets.Sparklines.SparklineType.line, setting);
activeSheet.setValue(1, 0, 1);
activeSheet.setValue(2, 0, -2);
activeSheet.setValue(3, 0, -1);
activeSheet.setValue(4, 0, 6);
activeSheet.setValue(5, 0, 4);
activeSheet.setValue(6, 0, -4);
activeSheet.setValue(7, 0, 3);
activeSheet.setValue(8, 0, 8);

## Enumeration members

### <a id="connect" name="connect"></a> connect

• **connect** = `2`

Fills gaps with a connecting element instead of leaving gaps for empty values in a data series.

___

### <a id="gaps" name="gaps"></a> gaps

• **gaps** = `0`

Leaves gaps for empty values in a data series, which results in a segmented line.

___

### <a id="zero" name="zero"></a> zero

• **zero** = `1`

Handles empty values in a data series as zero values, so that the line drops to zero for zero-value data points.
