I'm using phploc tool during build process which geterates an XML in it's own format:

<?xml version="1.0" encoding="UTF-8"?>
<phploc>
  <directories>30</directories>
  <files>71</files>
  <loc>2655</loc>
  <nclocClasses>1237</nclocClasses>
  <cloc>1403</cloc>
  <ncloc>1252</ncloc>
  <ccn>43</ccn>
  <ccnMethods>37</ccnMethods>
  <interfaces>0</interfaces>
  <classes>52</classes>
  <abstractClasses>1</abstractClasses>
  <concreteClasses>51</concreteClasses>
  <anonymousFunctions>0</anonymousFunctions>
  <functions>0</functions>
  <methods>95</methods>
  <publicMethods>85</publicMethods>
  <nonPublicMethods>10</nonPublicMethods>
  <nonStaticMethods>95</nonStaticMethods>
  <staticMethods>0</staticMethods>
  <constants>9</constants>
  <classConstants>4</classConstants>
  <globalConstants>5</globalConstants>
  <testClasses>9</testClasses>
  <testMethods>31</testMethods>
  <ccnByLoc>0.034345047923323</ccnByLoc>
  <ccnByNom>1.3894736842105</ccnByNom>
  <nclocByNoc>23.788461538462</nclocByNoc>
  <nclocByNom>13.021052631579</nclocByNom>
  <namespaces>0</namespaces>
</phploc>

Then I apply XSLT:

 <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:template match="/phploc">
          <build>
               <statisticValue key="directories" value="{directories}"/>
               <statisticValue key="files" value="{files}"/>
               <statisticValue key="loc" value="{loc}"/>
               <statisticValue key="nclocClasses" value="{nclocClasses}"/>
               <statisticValue key="cloc" value="{cloc}"/>
               <statisticValue key="ncloc" value="{ncloc}"/>
               <statisticValue key="ccn" value="{ccn}"/>
               <statisticValue key="ccnMethods" value="{ccnMethods}"/>
               <statisticValue key="interfaces" value="{interfaces}"/>
               <statisticValue key="classes" value="{classes}"/>
               <statisticValue key="abstractClasses" value="{abstractClasses}"/>
               <statisticValue key="concreteClasses" value="{concreteClasses}"/>
               <statisticValue key="anonymousFunctions" value="{anonymousFunctions}"/>
               <statisticValue key="functions" value="{functions}"/>
               <statisticValue key="methods" value="{methods}"/>
               <statisticValue key="publicMethods" value="{publicMethods}"/>
               <statisticValue key="nonPublicMethods" value="{nonPublicMethods}"/>
               <statisticValue key="nonStaticMethods" value="{nonStaticMethods}"/>
               <statisticValue key="staticMethods" value="{staticMethods}"/>
               <statisticValue key="constants" value="{constants}"/>
               <statisticValue key="classConstants" value="{classConstants}"/>
               <statisticValue key="globalConstants" value="{globalConstants}"/>
               <statisticValue key="testClasses" value="{testClasses}"/>
               <statisticValue key="testMethods" value="{testMethods}"/>
               <statisticValue key="namespaces" value="{namespaces}"/>
               <!--
               <ccnByLoc>0.043478260869565</ccnByLoc> 
               <ccnByNom>1.3894736842105</ccnByNom> 
               <nclocByNoc>26</nclocByNoc> 
               <nclocByNom>14.231578947368</nclocByNom> 
               -->
          </build>
     </xsl:template>
</xsl:stylesheet> 

And get D:\TeamCity\buildAgent\work\2ced091824a6e6f3\teamcity-info.xml (but it's written in one line)

<?xml version="1.0" encoding="UTF-8"?>
<build>

     <statisticValue key="files" value="71" />

     <statisticValue key="ncloc" value="1252" />
     <statisticValue key="ccn" value="43" />
     <statisticValue key="ccnMethods" value="37" />
     <statisticValue key="interfaces" value="0" />
     <statisticValue key="classes" value="52" />
     <statisticValue key="abstractClasses" value="1" />
     <statisticValue key="concreteClasses" value="51" />

     <statisticValue key="testClasses" value="9" />
     <statisticValue key="testMethods" value="31" />
     <statisticValue key="namespaces" value="0" />
</build>

So question is why there is no additional charts at *Project* / *Build Configuration* / Statistics page?

Also teamcity-info.xml doesn't appears in artifacts.

Using TeamCity Enterprise 6.0 EAP (build 15400)
