php - 散点图在 x 轴上重复相同的值

Question

我正在使用 ajax 调用绘制散点图。有些值在 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 轴上年份的值是重复的(2015 年和 2016 年)。散点图为 2015 年和 2016 年绘制了 2 个点。 我想显示具有不同 y 轴值的单个 x 轴值。

输出的图表应该是这样的——

感谢任何帮助。谢谢。

行有 2015 年和 2016 年的两个条目。

    "rows":
        [{"c":[{"v":"2006","f":null},{"v":"0","f":"$0"}]},{"c":
