<h3 dir="auto">Bug summary</h3>
<p dir="auto">When using symlog scale for an axis, a false warning is initially generated - independant of the data to plot - as soon as the mouse is moved over the axes.</p>
<h3 dir="auto">Code for reproduction</h3>
<div class="highlight highlight-source-python notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="import matplotlib.pyplot as plt

ax = plt.figure().add_subplot()
ax.set_yscale('symlog')

plt.show()"><pre class="notranslate"><span class="pl-k">import</span> <span class="pl-s1">matplotlib</span>.<span class="pl-s1">pyplot</span> <span class="pl-k">as</span> <span class="pl-s1">plt</span>

<span class="pl-s1">ax</span> <span class="pl-c1">=</span> <span class="pl-s1">plt</span>.<span class="pl-en">figure</span>().<span class="pl-en">add_subplot</span>()
<span class="pl-s1">ax</span>.<span class="pl-en">set_yscale</span>(<span class="pl-s">'symlog'</span>)

<span class="pl-s1">plt</span>.<span class="pl-en">show</span>()</pre></div>
<h3 dir="auto">Actual outcome</h3>
<p dir="auto">UserWarning: All values for SymLogScale are below linthresh, making it effectively linear. You likely should lower the value of linthresh.</p>
<h3 dir="auto">Expected outcome</h3>
<p dir="auto">"Nothing"</p>
<h3 dir="auto">Additional information</h3>
<p dir="auto">... maybe related to TkAgg?</p>
