Version: 3.2.0 Build id: I20060602-1317 The option of chart sometimes works ok, but sometimes it has the following error:
chart/org.eclipse.birt.chart.engine/src/org/eclipse/birt/chart/computation/withaxes/AutoScale.java
{
			throw new ChartException( ChartEnginePlugin.ID,
					ChartException.GENERATION,
					"exception.unknown.axis.type.tick.computations", 
					Messages.getResourceBundle( rtc.getULocale( ) ) );
		}
		if ( !bCategoryScale
				&& ( iType & NUMERICAL ) == NUMERICAL
				&& ( iType & LINEAR ) == LINEAR )
		{
			double dMax = asDouble( oMaximum ).doubleValue( );
			double dMin = asDouble( oMinimum ).doubleValue( );
			double dStep = asDouble( oStep ).doubleValue( );
			dTickGap = Math.min( Math.abs( dStep / ( dMax - dMin ) * dLength ),
					dLength )
					* iDirection;
		}
		else
		{
			dTickGap = dLength / ( nTicks - 1 ) * iDirection;
		}
		double d = dStart + dTickGap;
		final double[] da = new double[nTicks];
		for ( int i = 1; i < nTicks - 1; i++, d += dTickGap )
		{
			da[i] = d;
		}
		da[0] = dStart;
		da[nTicks - 1] = dEnd;
		setTickCordinates( null );
