    Hi, sorry that this post went unanswered for so long.

    Once you have an axis in the chart, moving its labels is only a matter of setting axis.labelsLocation property to one of predefined locations.

    For example, if you add two series with two distinct Y axis keys, your chart will have two Y axes. You can then take one of these axes and change its labelsLocation property.

    [_chart addSeriesForType:[IGColumnSeries class] usingKey:@"column" withDataSource:_dsh firstAxisKey:@"x" secondAxisKey:@"yLeft"];
    [_chart addSeriesForType:[IGLineSeries class] usingKey:@"line" withDataSource:_dsh firstAxisKey:@"x" secondAxisKey:@"yRight"];

    IGNumericYAxis *yRight = (IGNumericYAxis*)[_chart findAxisByKey:@"yRight"];
    yRight.labelsLocation = IGAxisLabelsLocationOutsideRight;
