雷达图怎么设置数据为倒序显示 about ios-echarts

[Pluto-Y]

@hjqiaho 你可以显示的时候通过formatter来进行调整

[hjqiaho]

@Pluto-Y 是像这样吗 具体formatter的值怎么写呢
NSMutableDictionary *trigger = [NSMutableDictionary dictionary];
[trigger setObject:@"axis" forKey:@"trigger"];
[trigger setObject:@"{b}
{a0}:{c0}" forKey:@"formatter"];

NSDictionary *radar = @{
                        @"legend":legend,
                        @"polar":polararray,
                        @"series":seriesarray,
                        @"tooltip":trigger,
                        @"title":[NSDictionary dictionaryWithObject:@"各科能力雷达图" forKey:@"text"]

你用的是哪一个版本你的iOS-Echarts，你用radar来设置option吗？还是怎么样？能贴一些关于你option的代码吗

[hjqiaho]

NSArray *templist = list[@"list"];
NSMutableArray *indicatortemp = [NSMutableArray array];
NSMutableArray *radarvalue = [NSMutableArray array];
for (int i = 0; i<templist.count; i++) {
NSDictionary *tempblank = @{@"max":@(-10),@"min":@(0),@"text":templist[i][@"blankName"]};
NSInteger rank = [[NSString stringWithFormat:@"%@",templist[i][@"rank"]] integerValue];
[indicatortemp addObject:tempblank];
[radarvalue addObject:@(-rank)];
}
NSArray *legenddata = @[@"学科排名"];
NSDictionary *legend = [NSDictionary dictionaryWithObjectsAndKeys:@"vertical",@"orient",@"right",@"x",@"bottom",@"y",legenddata,@"data",nil];
NSArray *polararray = @[ @{@"radius": @"80%",@"indicator":indicatortemp,@"scale":@(YES)},];
NSArray *seriesarray = @[@{@"name": @"各学科排名",@"sort":@"descending",@"type": @"radar",@"data":@[
@{@"name":@"学科排名",
@"value":radarvalue}
]}
];
NSMutableDictionary *trigger = [NSMutableDictionary dictionary];
[trigger setObject:@"axis" forKey:@"trigger"];
[trigger setObject:@"{b}
{c}:{c0}" forKey:@"formatter"];

NSDictionary *radar = @{
                        @"legend":legend,
                        @"polar":polararray,
                        @"series":seriesarray,
                        @"tooltip":trigger,
                        @"title":[NSDictionary dictionaryWithObject:@"各科能力雷达图" forKey:@"text"]
                        
                        };
PYOption *option = [RMMapper objectWithClass:[PYOption class] fromDictionary:radar];
[_kEchartView setOption:option];
[_kEchartView loadEcharts];

就是这段代码 版本就是前几天在这个git下载的

@hjqiaho 可以修改这下面的，应该是c0或者c前面加一个负号试试，建议使用原声属性来进行设置，你这种方式如果设置了多余的属性是不会有提示的，具体的demo看github上的demo

[trigger setObject:@"{b}{c}:{c0}" forKey:@"formatter"];

[hjqiaho]

加上负号就不返回数值或文字了 直接显示 {-c}
有没有直接倒序显示的方法？

[hjqiaho]

[label setObject:@"(function(params) {return -params.value;})" forKey:@"formatter"];

这么写解决了
