title: gnuplot highlighting points when with lines
body: <p>I have 4 points I would like to plot using gnuplot, but with lines. The problem is, I can't find how to highlight these 4 points on the drawn line. I would like for the plot to be a line through the points, but that these points are also clearly marked. An <a href="http://www.excel-easy.com/examples/images/line-chart/line-chart.png" rel="noreferrer">example</a> generated by excel. What I know is either drawing only points, or only a line with no highlighted points. Is a combination possible in gnuplot?</p>
