<p>Hi Jorge,</p>
<p>to my experience PyQtGraph might fit your needs best.<br />It is fast, it's easy to realize interactions between GUI and Backend (in both directions!) and it uses many<br />concepts that are commin in the Qt/PyQt world. You can easily deliver it as subpackage of your own project (~2.5 MB, MIT/X11 license) [1] </p>
<p>I recently started to use plotly too, but not for GUI programming. Nice to use as well, better default styles and much better documented than PyQtGraph. <br />Otherwise it's probably harder to be used in a GUI and to realize GUI <-> Backend interactions, e.g. if you want to update your plot fast or react on mouse clicks (please correct me if I'm wrong).</p>
<p>I'd love to see QtCharts [3] as part of QGIS distributions, as it is probably closest to common Qt paradigms like Model/View programming.</p>
<p>Greetings,</p>
<p>Benjamin</p>

<p class="v1MsoNormal">Hi all,</p>
<p class="v1MsoNormal"> </p>
<p class="v1MsoNormal"><span>I want to create o plot chart as a widget in my plugin. I already used MatPlotLib in the past, but I don't know it is the best choice.</span></p>
<p class="v1MsoNormal"><span> </span></p>
<p class="v1MsoNormal"><span>I know some plugins use PyQtGraph and others PyQwt (I think it was deceased for Qt5)</span></p>
<p class="v1MsoNormal"><span> </span></p>
<p class="v1MsoNormal"><span>Some features I consider relevant:</span></p>
<p class="v1MsoNormal"><span> </span></p>
<p class="v1MsoNormal"><span>1) Works native in Qgis enviroment, no need to install anything.</span></p>
<p class="v1MsoNormal"><span>2) Fast</span></p>
<p class="v1MsoNormal"><span>3) Easy to code</span></p>
<p class="v1MsoNormal"><span>4) Will not be discontinued in the near future</span></p>
<p class="v1MsoNormal"><span> </span></p>
<p class="v1MsoNormal"><span>What is the library best option? </span></p>
