Gnuplot log plot y-axis
<p>I have have a .txt file with some values as a function of iteration count. And I am trying to log plot it. I have managed to do this with the following code <code>plot 'solchange.txt' using 1:(log($2)) with lines</code></p>

<p>The x axis is perfect and the shape is perfect, but my y axis is weird. I want it to be say 10^-2 and 10^-3 and so on how can this be done?<a href="https://i.stack.imgur.com/1SSV7.png" rel="nofollow"><img src="https://i.stack.imgur.com/1SSV7.png" alt="enter image description here"></a></p>

<p>What does -16 even mean? My value stops at 10^-7</p>

<p>solchange.txt</p>
