    <p>You can also have a glance at <a href="http://www.ndepend.com/Metrics.aspx" rel="nofollow noreferrer">NDepend documentation about code metrics</a>. <em>Disclaimer: I am one of the developer of the tool NDepend.</em></p> <p>With the <a href="http://www.ndepend.com/Features.aspx#CQL" rel="nofollow noreferrer">Code Rule and Query over LINQ (CQLinq)</a> facility, it is possible to ask for code metric evolution/trending across two different snapshots in time of the code base. For example there is a default rule proposed: <a href="http://www.ndepend.com/DefaultRules/webframe.html?Q_Avoid_making_complex_methods_even_more_complex_%28Source_CC%29.html" rel="nofollow noreferrer">Avoid making complex methods even more complex</a> illustrated by the screenshot below:</p> <p><img src="https://i.stack.imgur.com/KLEnk.png" alt="Avoid making complex methods even more complex"></p> <p>Several metric trending rules are proposed like:</p> <ul> <li><a href="http://www.crap4j.org/" rel="nofollow noreferrer">Avoid decreasing code coverage by[enter link description here]<a href="http://www.crap4j.org/" rel="nofollow noreferrer">5</a> tests of types</a></li> <li><a href="http://www.ndepend.com/DefaultRules/webframe.html?Q_Types_that_used_to_be_100__covered_but_not_anymore.html" rel="nofollow noreferrer">Types that used to be 100% covered but not anymore</a></li> <li>and also, since you mentioned Crap4J the metric C.R.A.P can be written with CQLinq, and the query could be easily tweaked to see the trending in <a href="http://www.ndepend.com/DefaultRules/webframe.html?Q_C.R.A.P_method_code_metric.html" rel="nofollow noreferrer">C.R.A.P metric</a>. </li> </ul> <p>Concerning the visualization of code metric, NDepend lets visualize code metrics values through an <a href="http://www.ndepend.com/Doc_Treemap.aspx" rel="nofollow noreferrer">interactive treemap</a>: </p> <p><img src="https://i.stack.imgur.com/DFIcR.png" alt="Code Metric viualized through Treemap"></p>

    1. COThanks for the suggestion but as I said in the question, most of the code I'm concerned with is C++. I've seen jealousy-inducing demos of NDepend. I do appreciate the tip to look at their metrics documentation.

    2. COThen why not using CppDepend? http://www.cppdepend.com/ The C++ version of NDepend?

    3. COI hadn't noticed it existed. The only mention is down in the bottom right corner of the home page "below the fold" and NDepend is advertised heavily as a .Net tool. I will certainly give it a trial. I also suggest you talk to the marketing folks about getting a mention on the website banner to say you also do C++ and Java - I wonder how many others missed the C++ link. Thanks

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
