+
+Consider a dataset like [["February", 34], ["March", 20], ...]. This plugin
+allows you to plot such a dataset directly.
+
+To enable it, you must specify mode: "categories" on the axis with the textual
+labels, e.g.
+
+        $.plot("#placeholder", data, { xaxis: { mode: "categories" } });
+
+By default, the labels are ordered as they are met in the data series. If you
+need a different ordering, you can specify "categories" on the axis options
+and list the categories there:
+
+        xaxis: {
+                mode: "categories",
+                categories: ["February", "March", "April"]
+        }
+
+If you need to customize the distances between the categories, you can specify
+"categories" as an object mapping labels to values
+
+        xaxis: {
+                mode: "categories",
+                categories: { "February": 1, "March": 3, "April": 4 }
+        }
+
+If you don't specify all categories, the remaining categories will be numbered
+from the max value plus 1 (with a spacing of 1 between each).
+
+Internally, the plugin works by transforming the input data through an auto-
+generated mapping where the first category becomes 0, the second 1, etc.
+Hence, a point like ["February", 34] becomes [0, 34] internally in Flot (this
+is visible in hover and click events that return numbers rather than the
+category labels). The plugin also overrides the tick generator to spit out the
+categories as ticks instead of the values.
+
+If you need to map a value back to its label, the mapping is always accessible
+as "categories" on the axis object, e.g. plot.getAxes().xaxis.categories.
