php – 散点图在x轴上复制相同的值

我正在使用ajax调用绘制散点图.一些值在x轴上重复,而y轴值不同.示例 –

{
            "cols": [
                    {"id":"","label":"Sold Year","pattern":"","type":"string"},
                    {"id":"","label":"Unit Price","pattern":"","type":"number"}
                ],
            "rows": [{"c":[{"v":"2006","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2007","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2008","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2009","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2010","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2011","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2012","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2013","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2014","f":null},{"v":"0","f":"$0"}]},{"c":[{"v":"2015","f":null},{"v":"10700","f":"$10,700"}]},{"c":[{"v":"2015","f":null},{"v":"1280","f":"$1,280"}]},{"c":[{"v":"2016","f":null},{"v":"2500","f":"$2,500"}]},{"c":[{"v":"2016","f":null},{"v":"80500","f":"$80,500"}]},]}

在上面的示例中,x轴上的年份值是重复的(2015年和2016年).散点图为2015年和2015年提取了2个点.同样的2016年.

我想显示具有不同y轴值的单个x轴值.

图表输出应该像 –

任何帮助表示赞赏.谢谢.

解决方法:

行有2015年和2016年的两个条目.
