<div class="markdown_content"><p>I haven't found a way to change the direction of the error bars drawn in Gnuplot's key from horizontal to vertical. I think this feature is important because, e.g., it is confusing to have a key which shows horizontal error bars when only vertical error bars are present in a figure.</p> <p>The accepted answer from a web search is this: <a href="https://stackoverflow.com/questions/30218955/gnuplot-legend-errorbar-symbol-vertical" rel="nofollow">https://stackoverflow.com/questions/30218955/gnuplot-legend-errorbar-symbol-vertical</a>, which suggests a hack to manually draw the key using arrows and labels. This solution prevents using the many nice options already implemented for keys.</p> <p>Attached image shows an example plot with <code>yerrorbar</code> and <code>set key</code>, but the key draws only horizontal error bars.</p></div>
