Lucee5.3.8 CFChart URL禁用

Question

来自查询标记的Lucee CFChart类型饼：

<cfchart chartheight="600" chartwidth="800" showborder="true" title="Levels">
<cfchartseries query="#layout.querymap[layout.QueryName]#" type="pie" itemcolumn="Title" valuecolumn="Amount" />
</cfchart>

创建此HTML：

<map id="chart_8" name="chart_8">
<area shape="poly" coords="211,170,225,147,242,126,262,108,284,93,307,80,333,71,359,66,386,64,386,263,386,263" title="84000" alt="" href="#?series=0&category=xxxx&value=84000.0"/>

我只想要静态图像；没有href链接，没有区域标签，没有地图标签。

空url属性不起作用；文档搜索是徒劳的。

Answer 1

使用source属性cfchart。它将在指定的变量中存储生成图像的src属性。

<cfchart source="myChartImage" ...>
  <cfchartseries ...>
</cfchart>

<cfdump var="#myChartImage#">

使用您的示例，myChartImage将是一个值为/lucee/graph.cfm?img=f09a50705458509f66c5f37628f0bdea&type=png的字符串。

如果要将生成的图表映像存储为实际文件而不调用/lucee/graph.cfm，则需要使用getAsBinary属性通过cfhttp请求URI，并以字节数组的形式检索数据。然后，您可以将其写入磁盘，或将其编码为base64或十六进制等。

Answer 2

@亚历克斯-谢谢！这会产生我想要的裸img标记：

<cfchart chartheight="600" chartwidth="800" showborder="true" title="Levels" source="imagesource">
<cfchartseries query="#layout.querymap[layout.QueryName]#" type="pie" itemcolumn="Title" valuecolumn="DonationAmount" />
</cfchart><cfoutput>
<img src="#imagesource#">
</cfoutput>
