## ni-scale-legend

> A custom element that provides a scale legend.

Use it to visualize and change the axis modes of a graph, chart or intensity graph element.

It provides a list with all the axes of the graphs.

Each axis in the list has two buttons - one to turn on/off the autoscaling for that axis and
the other one sets the scale range to the data range (without changing the autoScale mode)

Example:
```html
<ni-cartesian-graph graph-ref="g1" value="[[2, 3, 5, 7, 11, 13, 17, 19],
                          [0, 1, 1, 2, 3, 5, 8, 13]]">
    <ni-cartesian-axis show label="Index" axis-position="bottom"></ni-cartesian-axis>
    <ni-cartesian-axis show label="Value" axis-position="left"></ni-cartesian-axis>
    <ni-cartesian-plot show label="Prime Numbers">
        <ni-cartesian-plot-renderer line-width="2" line-stroke="red">
        </ni-cartesian-plot-renderer>
    </ni-cartesian-plot>
    <ni-cartesian-plot show label="Fibonacci Numbers">
        <ni-cartesian-plot-renderer line-width="2" line-stroke="blue">
        </ni-cartesian-plot-renderer>
    </ni-cartesian-plot>
</ni-cartesian-graph>

<ni-scale-legend graph-ref="g1" mode="pan"></ni-scale-legend>
