tikzposter 环境中的 pgfplots 问题

Question

更新：我想在 TikZposter 中包含一些 pgfplots，但似乎遇到了一些问题。我之前在读取文件时遇到了问题，但根据 @percusse 的建议，我将数据移到了节点之外，这样就成功了。但是，现在我得到的图看起来很糟糕。

我正在处理的代码如下：

\documentclass{a0poster}

\usepackage{fancytikzposter} 
\usepackage{tikz,pgfplots}
\usepackage{pgfplotstable}
\usepackage{filecontents}
\pgfplotsset{compat=newest}

\addbibresource{mybibfile.bib}
\usepackage[hidelinks]{hyperref}

\setmargin{2.7}
\definecolor{mycol}{HTML}{116699} 
\definecolor{myblue}{HTML}{003E2F} 
\setfirstcolor{myblue}% default 116699
\usepackage[margin=\margin cm, paperwidth=84.1cm, paperheight=118.9cm]{geometry}

情节看起来很奇怪。我做错了什么？谢谢

我建议改用tikzposter部分基于fancytikzposter包的类。前者不存在同样的问题。

\documentclass[a0paper]{tikzposter}
\usetheme{Rays}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\pgfplotsset{compat=1.13}

\pgfplotstableread{

27  570 570
54  3098    5020
81  29578   36476
108 51040   57860
135 62493   65508
162 100736  107670
189 117150  122174
}\objnomQoS
\pgfplotstableread{
