PowerBI R Plot discrepancy

[mattmagoo]

Hi Guys,

I'm trying to display the movement of an object on a radial graph. I've managed to successfully plot the points in R and using geom_path draw a line based on the order of the records in the dataset.

When I apply is to PowerBI I seem to lose the order of the data and it just plots from high to low. I've attached the graphs from R Studio and PowerBI to show the difference. I'm sure I'm just missing a tiny thing, but can't figure out what it is.

I have the following script:

p <- ggplot(dataset, aes(extension, radius))+ geom_point(aes(extension, radius)) + geom_path() + coord_polar() + xlim(0, pi*2)
print(p)

My data is sorted like this:

extension	radius
1.90311	28.9289
1.81148	31.1281
1.7757	33.2769
1.77657	34.3312
1.77657	34.6795
1.77675	34.6795
1.77657	34.3312
1.77657	34.3312
1.77727	34.3312
...

PowerBI vs R Studio
