duplicate C-chart limits

johnmackintosh opened this issue · 1 comments

Some limits for c charts that occur after the final identified run are being duplicated for each date point, resulting in a sawtooth pattern /shading.
P charts appear to work correctly

line 466 might need another

centres <- centres[centres[, .I[start_date == max(start_date)], by = c(".datecol",".grpvar")]$V1]
