+
+ <p>Flot supports selections. You can enable
+ rectangular selection
+ or one-dimensional selection if the user should only be able to
+ select on one axis. Try left-clicking and drag on the plot above
+ where selection on the x axis is enabled.</p>
+
+ <p>You selected: <span id="selection"></span></p>
+
+ <p>The plot command returns a Plot object you can use to control
+ the selection. Try clicking the buttons below.</p>
+
+ <p><input id="clearSelection" type="button" value="Clear selection" />
+ <input id="setSelection" type="button" value="Select year 1994" /></p>
+
+ <p>Selections are really useful for zooming. Just replot the
+ chart with min and max values for the axes set to the values
+ in the "plotselected" event triggered. Try enabling the checkbox
+ below and select a region again.</p>
+
+ <p><input id="zoom" type="checkbox">Zoom to selection.</input></p>
