Two different series in single chart view
posted

Hi,

I am using two different series in single IGChartView. 

1) is IGColumnSeries and  2) is IGStackedColumnSeries.

Now problem is i couldn't apply two different series in single chart view. When i applied, it displayed some unnecessary white space between y-axis and its label. I have taken same axis for both series and set different keys for both of axis.

Is there any way to do this ?

Thanks..

    The chart is capable of displaying multiple category series side by side. Here's a small example with a stacked column and column series. This code snippet assumes that you have an array called _data with objects that have value1 and value2 properties for stacked data, value property for column data and labelString property for the labels on the x axis. You should see that there is no extra space in the axes and the columns are displayed side by side.

    - (void)viewDidLoad

    {

        NSArray *fields = @[@"value1", @"value2"];

        _chartView = [[IGChartView alloc]initWithFrame:self.view.frame];

        _categorySourceHelper = [[IGCategorySeriesDataSourceHelper alloc]initWithData:_data andValuePath:@"value"];

        _stackedChartDataSourceHelper = [[IGStackedSeriesDataSourceHelper alloc]initWithData:_data fields:fields labelPath:@"labelString"];

        IGColumnSeries *series = (IGColumnSeries*)[_chartView addSeriesForType:[IGColumnSeries class] usingKey:@"series" withDataSource:_categorySourceHelper firstAxisKey:@"xAxis" secondAxisKey:@"yAxis"];

        IGStackedColumnSeries *stackedSeries = (IGStackedColumnSeries*)[_chartView addStackedSeriesForType:[IGStackedColumnSeries class] usingKey:@"stackedSeries" withDataSource:_stackedChartDataSourceHelper firstAxisKey:@"xAxis" secondAxisKey:@"yAxis"];

        [self.view addSubview:_chartView];

    }
