# A Gauge chart with non-zero maximum and minimum values

Here's a straight-forward Gauge chart that shows how you can use a non-zero minimum value. It also uses the `colorsRanges` property to add the red, yellow, green, yellow and red bars around the Gauge. It's also adjustable by way of a small snippet of custom code (that's shown below in the code). By doing this instead of using the built-in adjusting, the movement of the needle can be animated using the `grow()` effect.

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.gauge.js"></script>

Put this where you want the chart to show up:

    <canvas id="cvs" width="350" height="350">
        [No canvas support]
    </canvas>

This is the code that generates the chart - it should be placed AFTER the canvas tag(s):
