Flot supports selections through the selection plugin. You can enable
|
|
rectangular selection or one-dimensional selection if the user should
|
|
only be able to select on one axis. Try left-click 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. Click the buttons below.
|
|
</p>
|
|
|
|
<p>
|
|
<button id="clearSelection">Clear selection</button>
|
|
<button id="setSelection">Select year 1994</button>
|
|
</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. Enable the checkbox below and select a region again.
|
|
</p>
|

<p>
|
|
<label><input id="zoom" type="checkbox" />Zoom to selection.</label>
