Error with X-axis and Dates #3

Closed jdtanner closed 6 years ago

jdtanner commented 6 years ago

Hello,

Using the following code:

library(qicharts2) Test <- read.csv('/home/jdtanner/Documents/Test.csv',head=TRUE,sep=",",stringsAsFactors = FALSE) Test$Date <- as.Date(Test$Date,"%d/%m/%y") qic(Date, Incidents, chart='run',data=Test, title='Incident QIC', ylab='Incident Count', xlab='Date',decimals=0,x.format="%d/%m/%y",x.angle=45)

With the following data in Test.csv:

Date,Incidents 27/11/17,241 26/11/17,228 25/11/17,286 24/11/17,285 23/11/17,267 22/11/17,293 21/11/17,298 20/11/17,217 19/11/17,313 18/11/17,327 17/11/17,262 16/11/17,294 15/11/17,289 14/11/17,274 13/11/17,205 12/11/17,290 11/11/17,303 10/11/17,262 09/11/17,288 08/11/17,245 07/11/17,246 06/11/17,233 05/11/17,288 04/11/17,309 03/11/17,279 02/11/17,265 01/11/17, 31/10/17,273 30/10/17,249 29/10/17,310 28/10/17,306 27/10/17,295 26/10/17,271 25/10/17,299

Yields a graph (as attached) with an incorrect x-axis. The final date value on the x-axis should be the latest date, but it is one day out; this is the same for all of the data.

Any ideas? John rplot

Fixed. Please test and report. The bug seemed to be triggered when dates changed from summer to winter time.
