I am setting the min, max and interval parameters but when i do that, chart gets distorted. 

I am using the following code to setup the chart; when i remove the min and maximum, i see the indicator without problem. Can hou help me, what i am missing? 

 IGFinancialPriceSeries *financialPriceSeries = (IGFinancialPriceSeries *)[infraChart addSeriesForType:[IGFinancialPriceSeries class] usingKey:@"financialPriceCandlestickSeries" withDataSource:source firstAxisKey:@"xAxis" secondAxisKey:@"yAxis"];

        financialPriceSeries.xAxis.labelsVisible = financialPriceSeries.yAxis.labelsVisible = NO;

        financialPriceSeries.displayType = IGPriceDisplayTypeCandlestick;

        financialPriceSeries.outline = [[IGBrush alloc] initWithColor:[[UIColor alloc] initWithWhite:0.5 alpha:1.0]];

        financialPriceSeries.transitionDuration = 1.0;

        financialPriceSeries.xAxis.majorStroke =  [[IGBrush alloc] initWithColor:[INVColor getColorFromHex:@"dbdbdb"]];

        financialPriceSeries.yAxis.majorStroke = financialPriceSeries.xAxis.minorStroke;

        financialPriceSeries.brush = [[IGBrush alloc]initWithColor:[INVColor getColorFromHex:@"009343"]];

        financialPriceSeries.negativeBrush = [[IGBrush alloc]initWithColor:[INVColor getColorFromHex:@"fd4040"]];

        financialPriceSeries.outline = [[IGBrush alloc] initWithColor:[UIColor clearColor]];

        financialPriceSeries.dataSource = source;

        financialPriceSeries.xAxis.labelsVisible = NO;

And then 

 IGSlowStochasticOscillatorIndicator *financialIndicator = (IGSlowStochasticOscillatorIndicator*) [infraChart addSeriesForType:[IGSlowStochasticOscillatorIndicator class] usingKey:@"financialIndicator" withDataSource:source firstAxisKey:@"xAxisIndicator" secondAxisKey:@"yAxisIndicator"];

                financialIndicator.xAxis.labelsVisible = financialIndicator.yAxis.labelsVisible = YES;

                financialIndicator.thickness = 3.0f;

                financialIndicator.transitionDuration = 1.0;

                financialIndicator.negativeBrush = [[IGBrush alloc] initWithColor:negativeColor];

                financialIndicator.brush = financialIndicator.negativeBrush;

                financialIndicator.xAxis.minorStroke = [[IGBrush alloc]initWithColor:[INVColor getColorFromHex:@"dbdbdb"]];

                financialIndicator.yAxis.minorStroke = financialIndicator.xAxis.majorStroke;

                financialIndicator.trendLineBrush = [[IGBrush alloc] initWithColor:trendlineColor];

                financialIndicator.trendLineThickness = 2;

                financialIndicator.xAxis.majorStrokeThickness = .5;

                financialIndicator.yAxis.majorStrokeThickness = .5;

                financialIndicator.xAxis.minorStrokeThickness = .5;

                financialIndicator.yAxis.minorStrokeThickness = .5;

                financialIndicator.xAxis.strokeThickness = .5;

                financialIndicator.yAxis.strokeThickness = .5;

                financialIndicator.yAxis.minimum = minVal;

                financialIndicator.yAxis.maximum = maxVal;

                financialIndicator.yAxis.interval = step;

                financialIndicator.xAxis.labelsVisible = NO;
