所有的KDJ都是这样么？

[JhonnyR]

对的，我的KDJ也是
一直报这样一个错：[Unknown process name] Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem.

运行一会就崩了

[Aaron]

可能是lua脚本语言与oc语言基本类型转换错误。最好提供给我一个稳定重现的demo来排查。

@MarcWeigert 您好，demo我准备好了，麻烦了，谢谢哈
GGCharts-KDJerror.zip

[Aaron]

改好了, 更新最新代码就可以了。如果线吗发直接把 kdj.lua替换了就好。

[zhoutl]

@MarcWeigert 好的，麻烦了

[Aaron]

问题关了吧。

[zhoutl]

@MarcWeigert 刚更新了kdj.lua，clean，并删除工程，重新编译打包 ，还是报一样的问题，然后用发你的demo工程试了下，也是一样的，

最新的kdj 用你的demo 没出现问题了啊

[zhoutl]

你好像只做了判断 ，没做其他处理，可能是忘了没有提交上来吧

我自己修改了，现在可以了

   if (d == 0) then
    rsvArray[i] = {rsv = 50}
    else
    rsvArray[i] = {rsv = (aryList[i][getCloseMethod] - funcLLV(i)) / (funcHHV(i) - funcLLV(i)) * 100}

    end

@MarcWeigert 是在d =0时候没有做 rsvArray[I]=50;
