如何使用开源 Java API - JOFC 设置带有 Open Flash Chart 2 图形的图例？
我有一个在 JBoss5 下运行的 Seam 2.2 应用程序。 1.在此应用程序中，我使用 Java Open Flash Chart（一种 Java API）成功开发了一些图形对于 打开 Flash 图表。
现在我想添加 X 和 Y 图例就像这个。
嗯，我有一张图形，它是正确渲染，然后我尝试使用以下方法设置 X Label：
... Chart.setXLegend(new Text("图例 X"));
但它不是显示图例，而是破坏了一些东西，导致图形呈现完全空白。
这是图形正确渲染时生成的 JSon。
{"y_axis":{"min":388,"max":866,"steps":20},"title":{"text":"Gráfico de gasto mensal com Combustível"},"bg_colour":"#FFFFFF","is_decimal_separator_comma":0,"elements":[{"values":[{"tip":"R$:610.0\n05/2010","top":610},{"tip":"R$:488.0\n06/2010","top":488},{"tip":"R$:634.57\n07/2010","top":634.57},{"tip":"R$:766.0\n08/2010","top":766},{"tip":"R$:396.0\n09/2010","top":396},{"tip":"R$:610.0\n10/2010","top":610}],"type":"bar"}],"num_decimals":2,"is_fixed_num_decimals_forced":0,"x_axis":{"labels":{"labels":["05/2010","06/2010","07/2010","08/2010","09/2010","10/2010"]}},"is_thousand_separator_disabled":0}
我深入研究了它，结果发现每当我尝试添加 x 图例以及上面显示的代码片段时，JSon 实际上不是由 JOFC 生成的。
我在网上找不到太多关于 JOFC 的有用文档，而且 API 本身也没有很好的文档记录，所以我完全迷失在尝试添加这个简单的 x 标签上，这应该是最简单的部分:( 。对此有任何想法。
更新：
现在我刚刚下载了 JOFC 源代码，并将看一下。
I have a Seam 2.2 app running under JBoss5.1. In this application I have successfully developed some Graphics using Java Open Flash Chart, which is a Java API for Open Flash Chart.
Now I would like to add a X and Y legend like this one.
Well I have a graphic which is rendering properly and than I try to set X Label using:
...
chart.setXLegend(new Text("Legenda X"));
But than instead of showing the legend it corrupts something which causes the graphic to renders completely blank.
This is the generated JSon when the graphics renders correctly.
{"y_axis":{"min":388,"max":866,"steps":20},"title":{"text":"Gráfico de gasto mensal com Combustível"},"bg_colour":"#FFFFFF","is_decimal_separator_comma":0,"elements":[{"values":[{"tip":"R$:610.0\n05/2010","top":610},{"tip":"R$:488.0\n06/2010","top":488},{"tip":"R$:634.57\n07/2010","top":634.57},{"tip":"R$:766.0\n08/2010","top":766},{"tip":"R$:396.0\n09/2010","top":396},{"tip":"R$:610.0\n10/2010","top":610}],"type":"bar"}],"num_decimals":2,"is_fixed_num_decimals_forced":0,"x_axis":{"labels":{"labels":["05/2010","06/2010","07/2010","08/2010","09/2010","10/2010"]}},"is_thousand_separator_disabled":0}
I took a deeply look at it and turns out that whenever I try to add the x legend with the code fragment showed above the JSon is actually NOT generated by JOFC.
I could not find much useful documentation on JOFC on the web and the API itself is not very well documented, so I am completely lost on trying to add this simple x label, which should be the easiest part :( . Any Ideas on that.
An update:
Now I just have downloaded JOFC source code and will take a look at this.

JOFC 页面上似乎有一个未解决的问题：http://code .google.com/p/jofc2/issues/detail?id=29
它建议了一种调用该函数的解决方法，例如：
It looks like there's an open issue on the JOFC page: http://code.google.com/p/jofc2/issues/detail?id=29
It suggests a workaround of calling the function like:
我会尝试使用Open Flash Grapix，它更容易使用，并且只需在FlashVars上设置参数即可。
打开 Flash Grapix
I would try with Open Flash Grapix, it is easier to use, and just sets parameters on FlashVars.
