<code class="function">SetDrawBrokenLines</code> determines how to plot lines with
missing data points. By default, PHPlot will
act as if the point does not exist, connecting the points before and after
the missing datum in the usual way. Use SetDrawBrokenLines to leave a gap
between the points before and after missing data instead.
    </p><p>
This only applies to 'lines', 'linepoints', and 'squared' plot types.

True to break the lines at missing data points. False to connect the
lines around missing data.
          </p></dd></dl></div></div><div class="refsect1"><a id="idp1377953668"></a><h2>Notes</h2><p>
The default is to ignore missing data and connect lines around missing points.
    </p><p>
A missing data point is indicated by an empty string in the corresponding
position for the dependent variable value in the data array.
This is the Y value for vertical plots, or X value for horizontal plots.
