<h2>Memory Graph Menu </h2>
<p>The <strong>Memory Graph</strong> menu is available whenever a <span
class="code">.npi</span> data file is opened that contains memory usage trace
data. Use it to modify how the graph is calculated, view memory statistics, and
control how the memory information is displayed. </p>
