The markers you used in Excel & python for the line chart to specify the points. You didn't talk about it in R. Thanks.

Hi Roman, thanks for reaching out! You can include points on the line chart with ggplot. It's rather a hack that adds points on the chart, but I think it looks quite alright. Here is an example code which add the points to the line chart: combo <- ggplot(df_kdnuggets, aes(x = Year, y = Participants, Python.Users)) + geom_bar(aes(y = df_kdnuggets$Participants), stat = "identity", fill = "black") + geom_line(aes(y = df_kdnuggets$Python.Users*max(df_kdnuggets$Participants)), stat = "identity", color = "red", size = 2) + geom_point(aes(y=df_kdnuggets$Python.Users*max(df_kdnuggets$Participants)), stat = "identity", color = "red", size = 5) + scale_y_continuous(sec.axis = sec_axis(~./max(df_kdnuggets$Participants)*100, name = "Python Users in %")) + ggtitle("KD Nuggets Survey Python Users (2012 - 2019)") Hope this helps! Best, 365 Eli
