There is such a piece in the cfnindex body.

<script class="code" type="text/javascript">
    //<![CDATA[
    $(document).ready(function () {
        $.jqplot._noToImageButton = true;
        var graph = ...

That's graphall the original data.
Well, from a raster Canvas, of course, it is impossible to read anything after the graph has already been rendered.

It can be seen that the graph is built by the jqplot component. You need to tweak its API by injecting your userscript into the page, for example.
