<p>Flot supports selections through the selection plugin.
|
| 20 |
You can enable rectangular selection |
| 21 |
or one-dimensional selection if the user should only be able to |
| 22 |
select on one axis. Try left-click and drag on the plot above |
| 23 |
where selection on the x axis is enabled.</p>
|
| 24 |
|
| 25 |
<p>You selected: <span id="selection"></span></p> |
| 26 |
|
| 27 |
<p>The plot command returns a plot object you can use to control
|
| 28 |
the selection. Click the buttons below.</p>
|
| 29 |
|
| 30 |
<p><input id="clearSelection" type="button" value="Clear selection" /> |
| 31 |
<input id="setSelection" type="button" value="Select year 1994" /></p> |
| 32 |
|
| 33 |
<p>Selections are really useful for zooming. Just replot the
|
| 34 |
chart with min and max values for the axes set to the values |
| 35 |
in the "plotselected" event triggered. Enable the checkbox |
| 36 |
below and select a region again.</p>
|
| 37 |
|
| 38 |
<p><input id="zoom" type="checkbox">Zoom to selection.</input></p> |
