values' decimal places not consistent

[babygal]

qreal u, fYval ;
        fYval = 0.000;
        for( int i=0; i<=10; i++)
                     {
                         painter->drawLine(QPointF(yAxisX - 3, fYpos), QPointF(yAxisX, fYpos));
 
                         painter->drawText(QPointF(chartOuterMargin, fYpos), QString("%1").arg(fYval,0,'g',3));
                         fYval += u;
                         fYpos -= fStepYpos;
                                             }

qreal u, fYval ;
        fYval = 0.000;
        for( int i=0; i<=10; i++)
                     {
                         painter->drawLine(QPointF(yAxisX - 3, fYpos), QPointF(yAxisX, fYpos));

                         painter->drawText(QPointF(chartOuterMargin, fYpos), QString("%1").arg(fYval,0,'g',3));
                         fYval += u;
                         fYpos -= fStepYpos;
                                             }

fYval values' decimal places displayed (from code line : drawText) are inconsistent, e.g :

fYval: 0.005
fYval: 0.01
fYval: 0.015
fYval: 0.02
fYval: 0.025
fYval: 0.03
fYval: 0.035
fYval: 0.04
fYval: 0.045
fYval: 0.05
fYval: 0.055

How to make the decimal places of fYval consistent? In this case I want it to be :
fYval: 0.005
fYval: 0.010
fYval: 0.015
fYval: 0.020
fYval: 0.025
fYval: 0.030
fYval: 0.035
fYval: 0.040
fYval: 0.045
fYval: 0.050
fYval: 0.055

Use this

QString("%1").arg(fYval, 0, 'f', 3);

QString("%1").arg(fYval, 0, 'f', 3);
