<code class="function">SetPrecisionY</code> sets the desired numeric precision
for Y tick and data labels, and also enables 'data' mode formatting
of those labels with <a class="xref" href="SetYLabelType.html" title="SetYLabelType"><span class="refentrytitle">SetYLabelType</span></a>.

This function is retained for compatibility, but use of
<a class="xref" href="SetYLabelType.html" title="SetYLabelType"><span class="refentrytitle">SetYLabelType</span></a> is preferred.

The desired numeric precision.
This is the number of decimal positions to output.
          </p></dd></dl></div></div><div class="refsect1"><a id="idp1378710548"></a><h2>Notes</h2><p>
Setting numeric precision with this function automatically enables 'data'
mode formatting as if <code class="literal">SetYLabelType('data')</code> was called.
    </p><p>
The default is to format numbers with 1 decimal position, but only
if 'data' mode formatting is selected.
    </p><p>
This function applies to both Y tick labels and Y data labels.
(Y data labels are data value labels within the plot area for vertical plots,
or axis data labels for horizontal plots.
See <a class="xref" href="conc-labels.html" title="3.6. Labels">Section 3.6, &#8220;Labels&#8221;</a> for more on labels.)
Using 'data' format for Y axis data labels only makes sense
when your data array contains numeric data in the label position.
    </p><p>
See <a class="xref" href="SetPrecisionX.html" title="SetPrecisionX"><span class="refentrytitle">SetPrecisionX</span></a> for X tick and data labels.
    </p><p>
This function also affects pie chart labels, for backward compatibility.
When drawing a pie chart, if <a class="xref" href="SetPieLabelType.html" title="SetPieLabelType"><span class="refentrytitle">SetPieLabelType</span></a> was not called,
and <code class="function">SetPrecisionY</code> was called, then the precision set
with <code class="function">SetPrecisionY</code> is used when formatting pie chart
labels.
    </p></div><div class="refsect1"><a id="idp1378714852"></a><h2>History</h2><p>
Starting with PHPlot-5.0.6, using <code class="code">SetPrecisionY($n)</code>
is exactly the same as calling <code class="code">SetYLabelType('data', $n)</code>.
