A connected scatterplot is really close from a scatterplot, except that dots are linked one to each other with lines. This means that the values of your X axis must be ordered to make this type of

representation useful. Thus, connected scatter plot are often used for time series where the X axis represents time. If you want to fill the area under the line you will get an area chart. If you don’t

find the customization you need, don’t hesitate to visit the scatterplot section or the line chart section that have many tips in common.
