title: pointplot not showing line when palette is set
body: <p>when I use any palette in <code>sns.pointplot()</code> the line is not showing no matter if I set <code>join=True</code>, or choose any linestyle, the points have palette colors, but they are not connected. Should it be like that? Or is there other parameter I can set to connect the points? The line can be one color.</p>
