How to add data labels to a radar chart

[maxlc]

Hi,

Hope everything's going fine for you.

I'm currently working with the fmsb package to build a radarchart.

I've made a dataframe like this one to be able to draw the chart :

spyder_data <- data.frame(DuelsAeriensOff = c(20, 0, DuelsAeriensOff),
                   DuelsAeriensOffGagnes = c(1, 0, DuelsAeriensOffGagnes),
                   ButTirs16  = c(0.2, 0, ButTirs16),
                   TirsBloques = c(1, 0, TirsBloques),
                   ConversionPasses16 = c(0.2, 0, ConversionPasses16),
                   PassesMatch16 = c(20, 0, PassesMatch16),
                   PassesReussies16 = c(1, 0, PassesReussies16),
                   DangerositePassesCles = c(0.2, 0, DangerositePassesCles),
                   PartCentresSurface = c(1, 0, PartCentresSurface),
                   DistancePassesSurface = c(20, 0, DistancePassesSurface),
                   row.names = c("max", "min", "value"))

and I'm drawing the radarchart with the fonction like this :

radarchart(spyder_data,
           vlabels = labels,
           vlcex = 0.5,
           cglcol = "grey",
           cglty = 1,
           pcol = c(scales::alpha("orange", 1)),
           pfcol = c(scales::alpha("orange", 0.4)),
           plwd = 2
           )

Everything is going fine and I'm obtaining this chart :

But I would like to add data labels next to my oranges chart's points, who are contain in the third column of my spyder_data dataframe.

I searched for hours this afternoon but I didn't find anything... except maybe using the function text() but I don't know how to do it since it's a specific chart.

If anyone have an idea about my issue, I would be very grateful. Have a good evening.

have you tested the example code you shared ?

Error in data.frame(DuelsAeriensOff = c(20, 0, DuelsAeriensOff), DuelsAeriensOffGagnes = c(1,  : 
  object 'DuelsAeriensOff' not found

Of course I did, if I didn’t I would not have the graph. You may have this error because DuelAeriensOff is calculated before in my script !

Im afraid this makes it harder to help you. Also the third column of labels you want to add, seems absent.

My dataframe is looking like that

Is there no way to use the line "value" as data label to get the values next to the points on the graph ?
