Add additional data to tooltip in iOS which does not belongs to x&y-axis of graph


I followed this demo to draw Column charts. (<a href="https://www.highcharts.com/ios/demo/column-rotated-labels" rel="nofollow">https://www.highcharts.com/ios/demo/column-rotated-labels</a>).

What Issue I am facing is : I can easily show x-axis and y-axis information in tooltip. But I am not able to put additional information in tooltip from a different array (suppose array for depicting required qty for item).

I tried to do like this ;

tooltip.pointFormat = [NSString stringWithFormat:@"Velocity : {point.y:.2f} Remaining Quantity : %@",RemainingQtyArray]; It will print whole array in tooltip. tooltip.pointFormat = [NSString stringWithFormat:@"Velocity : {point.y:.2f} Remaining Quantity : %@",RemainingQtyArray[i++]]; It will print last item from array. So, how can i put additional info so that when anyone taps on graph, it will show this info too.

Check this <a href="http://jsfiddle.net/0sarjr1d/1" rel="nofollow">Fiddle</a> demo in JS

Tooltip in JS way

tooltip: { pointFormat: 'Population in 2017: <b>{point.y:.1f} millions</b><br>Extra One: <b>{point.data1}</b><br>Extra Two: <b>{point.data2}</b>' },

Series data in JS way

data: [ {name:'Shanghai', y:24.2,data1:'Aa',data2:'Ba'}, {name:'Beijing', y:20.2,data1:'Ab',data2:'Bb'}, {name:'Karachi', y:14.2,data1:'Ac',data2:'Bc'}, {name:'Shenzhen', y:13.2,data1:'Ad',data2:'Bd'}, ],

Through <a href="https://www.highcharts.com/ios/demo/column-rotated-labels" rel="nofollow">doc</a> I convert into ios.

For ios

HITooltip *tooltip = [[HITooltip alloc]init]; tooltip.pointFormat = @"Population in 2017: <b>{point.y:.1f} millions</b><br>Extra One: {point.data1}<br>Extra Two: {point.data2}";

For ios series data

column.data = [NSMutableArray arrayWithObjects: @{ @"name":@"Shanghai", @"y":@23.7, @"data1":@'Aa', @"data2":@'Ba' }, @{ @"name":@"Shanghai", @"y":@16.1, @"data1":@'Aa', @"data2":@'Ba' }, @{ @"name":@"Karachi", @"y":@14.2, @"data1":@'Aa', @"data2":@'Ba' }, @{ @"name":@"Shenzhen", @"y":@14, @"data1":@'Aa', @"data2":@'Ba' } , nil];
