+About
+-----
+
+Flot is a Javascript plotting library for jQuery. Read more at the
+website:
+
+  http://code.google.com/p/flot/
+
+Take a look at the examples linked from above, they should give a good
+impression of what Flot can do.
+  
+
+Installation
+------------
+
+Just include the Javascript file after you've included jQuery. Note that you
+need to download a version of Excanvas (I currently suggest you take
+the one on the Flot homepage as it contains a bugfix for drawing
+filled shapes) which is canvas emulation on Internet Explorer. And
+don't worry, the emulation is otherwise working fine.
+
+You can include the excanvas script like this:
+
+  <!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
+
+Also note that you need at least jQuery 1.2.1.
+
+
+Basic usage
+-----------
+
+Create a placeholder div to put the graph in:
+
+   <div id="placeholder"></div>
+
+You need to set the width and height of this div, otherwise the plot
+library doesn't know how to scale the graph. You can do it inline or
+with an external stylesheet.
+
+Then on document ready, run the plot function:
+
+  $.plot($("#placeholder"), data, options);
+
+Here, data is an array of data series and options is an object with
+settings if you want to customize the plot. Take a look at the
+examples for some ideas of what to put in or look at the reference
+in the file "API.txt".
+
+The plot function immediately draws the chart and then returns a Plot
+object with a couple of methods.
+
+
+What's with the name?
+---------------------
+
+Well, "Flot" is like "Plot".
+
+And if you look up "flot" in a Danish-to-English dictionary, some up
+the words that come up are "good-looking", "attractive", "stylish",
+"smart", "impressive", "extravagant". One of the main goals with Flot
+is pretty looks.
--- a/TODO
+++ b/TODO
+These are mostly ideas, that they're written down here is no guarantee
+that they'll ever be done. If you want something done, feel free to
+say why or come up with a patch. :-)
+
+support segmented lines
+  - put in null value to signify a break in the data set
+
+grid configuration
+  - how ticks look like
+  - (handling of 1/2 linewidth hack in grid?)
+
+selection
+  - user should be able to cancel selection with escape
+  - select points
+
+interactive zooming
+  - convenience zoom(x1, y1, x2, y2)? and zoomOut() (via zoom stack)?
+  - auto-zoom mode?
+  - auto-margin
+
+handling time data
+  - dataformat
+  - axis adjustment
+  - tick generation
+
+support for highlighting stuff
+  - lines
+  - points
+
+legend
+  - interactive auto-highlight of graph?
+
+interactive hot points
+  - fire event with value
+
+interactive hover over lines
+  - fire event with graph id

+       attractive look. Put in a placeholder, make sure you set its
+       dimensions (otherwise the plot library will barf) and call the
+       plot function with the data. The axes are automatically

+
+    <p>There are plenty of options you can set to control the precise
+    looks of your plot. You can control the axes, the legend, the
+    default graph type, the look of grid, etc.</p>
+
+    <p>The idea is that Flot goes to great lengths to provide <b>sensible
+    defaults</b> which you can then customize as needed for your
+    particular application. If you've found a use case where the
+    defaults can be improved, please don't hesitate to give your
+    feedback.</p>
