在iOS中的工具提示中添加不属于图表的x和y轴的其他数据 [英] Add additional data to tooltip in iOS which does not belongs to x&y-axis of graph

问题描述

我按照此演示绘制了柱形图. ( https://www.highcharts.com/ios/demo/column-rotated -标签).

I followed this demo to draw Column charts. (https://www.highcharts.com/ios/demo/column-rotated-labels).

我面临的问题是:我可以轻松地在工具提示中显示x轴和y轴信息.但是我无法从其他数组(假设数组用于描述项目所需的数量)将其他信息放入工具提示中.

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).

我试图这样做；

tooltip.pointFormat = [NSString stringWithFormat:@速度:{point.y:.2f} 剩余数量:％@，RemainingQtyArray]; 它将在工具提示中打印整个数组. tooltip.pointFormat = [NSString stringWithFormat:@速度:{point.y:.2f} 剩余数量:％@，RemainingQtyArray [i ++]]; 它将打印数组中的最后一项. 因此，我该如何放置其他信息，以便当任何人点击图形时，它也会显示此信息.

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.

想要这样的工具提示.

推荐答案

在 Fiddle 演示中进行检查JS

Check this Fiddle demo in JS

JS方式的工具提示

 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>'
    },

以JS方式进行系列数据

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'},
    ],

通过 doc 我将其转换为ios.

Through doc I convert into ios.

对于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}";

用于iOS系列数据

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];
