### getLogBase() {#getLogBase}
```
public double getLogBase()
```


Gets the logarithmic base for a logarithmic axis.

 **Remarks:** 

The property is not supported by MS Office 2016 new charts.

Valid range of a floating point value is greater than or equal to 2 and less than or equal to 1000. The property has effect only if [getType()](../../com.aspose.words/axisscaling/\#getType) / [setType(int)](../../com.aspose.words/axisscaling/\#setType-int) is set to [AxisScaleType.LOGARITHMIC](../../com.aspose.words/axisscaletype/\#LOGARITHMIC).

Setting this property sets the [getType()](../../com.aspose.words/axisscaling/\#getType) / [setType(int)](../../com.aspose.words/axisscaling/\#setType-int) property to [AxisScaleType.LOGARITHMIC](../../com.aspose.words/axisscaletype/\#LOGARITHMIC).

 **Examples:**
