Java 更改折线图Apache POI的颜色
我已经使用ApachePOI生成了一个折线图。我需要更改图表中的默认颜色。我可以使用RGB代码定义每行的特定颜色吗 我的代码如下Java 更改折线图Apache POI的颜色,java,excel,charts,apache-poi,Java,Excel,Charts,Apache Poi,我已经使用ApachePOI生成了一个折线图。我需要更改图表中的默认颜色。我可以使用RGB代码定义每行的特定颜色吗 我的代码如下 Drawing drawing = sheet4.createDrawingPatriarch(); ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 1, 1, 17, 22); Chart chart = drawing.createChart(anchor); ChartLegend legend =

我一直是完整示例的朋友。然后其他人可以复制这个,而不需要猜测Excel
工作表的外观
下面的完整示例不会创建Office Open XML格式(*.xlsx
)的新Excel
工作簿,其中包含一些示例数据和折线图
第一个代码部分创建一个折线图,apachepoi
version3.17
根据默认值创建折线图
然后在第二部分代码中,我定制了图表。代码部分被注释,以显示它们应该做什么。之后,自定义图表也与OpenOffice兼容。apachepoi
默认图表与OpenOffice
/Libreoffice
Calc
不兼容。至少最新版本3.17
为了定制,需要了解内部低级对象apachepoi
用作基本对象的相关知识。这些都包含在。不幸的是,没有更多的API
docpublic可用。因此,必须下载ooxml-schemas-1.3-sources.jar
,然后自己做javadoc
才能获得文档
还应该知道,Office Open XML格式(*.xlsx
)的文件只是ZIP
归档文件。因此,您可以将其解压缩并查看/xl/charts/chart1.xml
。如果在apache poi
创建图表后执行此操作,并在Excel
中完成所需更改后重新保存XML,然后将该XML与XML进行比较,则将看到所需的XML更改
