<h3>Example 3 - Scatter Plot</h3>
<p>This example uses the same data set as example 1, but using the <code>Scatter</code>
plot type to show the correlation betweent CameraTemperature and AmbientTemperature.
The first tag specified on the command line is the independent variable (plotted
along the X axis), and the rest are the dependent variables (Y axis). Note that
the legend doesn't appear in this plot because there is only one dependent
variable, so instead the Y-axis is labelled with its name.</p>
<p>The plot <code>Style</code>
has been changed to <code>Marker</code> to show markers for the data points
instead of connecting them with lines, and <code>Fill</code> has been added to
show filled markers instead of outlines. The fill is partially transparent with a
default opacity of 20%, but this has been changed to 10% via the <code>Marks</code>
setting so points which occur few times in the dataset will show a noticably lighter
color.</p>

strings of numbers, the <code>Split</code> setting of the
<a href="ExifTool.html#Plot">API Plot option</a> must be used to split the values into
separate lines in the plot. Here is an example of the first Accelerometer value in the
file:</p>
<pre><span class='blk'>> </span>exiftool test.mp4 -ee -accelerometer -s2 --a
<span class='blk'>Accelerometer: +0.12 +0.96 -0.09</span></pre>
<p>And this command was used to generate the following plot:</p>
<pre>exiftool test.mp4 -w plot4.svg -ee -accelerometer -plot -api plot="split,legend=30 107" \
-api plot="title=Accelerometer Readings,ylabel=G Force,xlabel=Sample Number"
</pre>

<h3>Example 5 - Multi Plots</h3>
<p>This example demonstrates the <code>Multi</code> setting to draw multiple
<code>Histogram</code> plots in 2 columns. The <a href="ExifTool.html#Filter">API Filter</a>
