<p>When a graph has been generated in Shiny, if the values change (via a reactive function), the graph is <em>not regenerated</em>, only the data is <em>updated</em>. If you have changed specific options in the graphic (such as maximum y axis value, charts title, …) these will not be updated. This behavior can be controlled with <code>auto_update</code> argument (available in <code><a href="../reference/apexchart.html">apexchart()</a></code> and <code><a href="../reference/apex.html">apex()</a></code>) :</p>
<p>By default, <code>auto_update</code> is <code>TRUE</code> :</p>

<p>If you want to re-create the whole chart, set the option to <code>FALSE</code>:</p>
<div class="sourceCode" id="cb3"><pre class="downlit sourceCode r">

<p>Be sure to use <code><a href="https://rdrr.io/pkg/shiny/man/isolate.html" class="external-link">shiny::isolate()</a></code> to block any reactivity in <code>renderApexchart</code> function and to set <code>auto_update</code> to FALSE to prevent updating twice. Then you can use in an observe function (or any reactive function) <code><a href="../reference/apexchartProxy.html">apexchartProxy()</a></code> with the output id to get the chart instance and <code><a href="../reference/ax_proxy_series.html">ax_proxy_series()</a></code> to update data.</p>
