This sample uses <a href="../intro/graduatedPanels.html">Graduated Panels</a> and <code>Panel.alignmentFocusName</code> to line up thermometer scales.
|
|
</p>
|
|
<p>
|
|
The thermometers are resizable, with two types. For the first two (default), resizing the thermometer reduces
|
|
or increases the range of the values. For the second two (<code>type: "scaling"</code>), resizing
|
|
the thermometer keeps the range, and scales the thermometer.
