Line Chart Dynamic Updating

[asdfasdf126]

I am trying to create a line graph that updates as it gets points. The problem I'm having is the graph will not update unless i am interacting with it. Either moving the graph or even tapping it. I'm out of ideas on how to remedy this problem and i have not been able to find anything that comes close to working.

LineChartData *data = self.chartView.data;

if(data != nil)
{
    LineChartDataSet *set = [data getDataSetByIndex:0];

    if(set == nil)
    {
        set = [[LineChartDataSet alloc] init];

        set.drawCirclesEnabled = false;
        set.drawValuesEnabled = false;
        [set setColor:UIColor.blackColor];
        set.lineWidth = 1.0;
        set.valueFont = [UIFont systemFontOfSize:9.f];
        set.drawCubicEnabled = true;

        NSArray *gradientColors = @[
                                    (id)[ChartColorTemplates colorFromString:@"#00ff0000"].CGColor,
                                    (id)[ChartColorTemplates colorFromString:@"#ffff0000"].CGColor
                                    ];
        CGGradientRef gradient = CGGradientCreateWithColors(nil, (CFArrayRef)gradientColors, nil);

        set.fillAlpha = 1.f;
        set.fill = [ChartFill fillWithLinearGradient:gradient angle:90.f];
        set.drawFilledEnabled = true;

        CGGradientRelease(gradient);

        [data addDataSet:set];
    }

    [self.chartView setVisibleXRangeMaximum:MAXVALUES];
    [self.chartView setVisibleXRangeMinimum:MAXVALUES];

    [data addXValue:[NSString stringWithFormat:@"%.f", xVal]];
    [data addEntry:[[ChartDataEntry alloc] initWithValue:yVal xIndex:xVal] dataSetIndex:0];

    int move = [[set entryForIndex:[set entryCount] - 1] xIndex];

    [self.chartView notifyDataSetChanged];
    [self.chartView moveViewToX:(move - MAXVALUES < 0)?0:move - MAXVALUES];
}
else
    self.chartView.data = [[LineChartData alloc] init];
