<p>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.

<h4>Geometry Path Strings</h4>
<p>
The <b>GoJS</b> <a href="../api/symbols/Geometry.html" target="api">Geometry</a> class controls the "shape" of a <a href="../api/symbols/Shape.html" target="api">Shape</a>,
whereas the <a href="../api/symbols/Shape.html#fill" target="api">Shape.fill</a> and <a href="../api/symbols/Shape.html#stroke" target="api">Shape.stroke</a> and other shape properties control the colors and appearance of the shape.
For common shape figures, there are predefined geometries that can be used by setting <a href="../api/symbols/Shape.html#figure" target="api">Shape.figure</a>.
However one can also define custom geometries.
</p>
<p>
One can construct any Geometry by allocating and initializing a <a href="../api/symbols/Geometry.html" target="api">Geometry</a> of at least one <a href="../api/symbols/PathFigure.html" target="api">PathFigure</a> holding some <a href="../api/symbols/PathSegment.html" target="api">PathSegment</a>s.
But you may find that using the string representation of a Geometry is easier to write and save in a database.
Use the static method <a href="../api/symbols/Geometry.html#parse" target="api">Geometry.parse</a> or the <a href="../api/symbols/Shape.html#geometryString" target="api">Shape.geometryString</a> property to transform a geometry path string into a <a href="../api/symbols/Geometry.html" target="api">Geometry</a> object.
