R visual using bupaR only displaying 16 out of 120k cases

[T_von_Axt]

Hello,

I am trying ot use bupaR for some process mining, but after I generate the eventlog with bupaR, the visuals created with the other libraries (e.g. diagrammeR) only show maximum 16 cases out of 120k.

I've read in documentation that powerBI supports up to 150k cases in R visuals. 

Could someone please point to me what I am doing wrong?

my dataset contains the following columns:

ContractId	Status	LastUpdate	Project	Contract Type	Index

the R script I am using is the following:

# The following code to create a dataframe and remove duplicated rows is always executed and acts as a preamble for your script: 

# dataset <- data.frame(CONTRACTID)
# dataset <- unique(dataset)

# Paste or type your script code here:
library(bupaR)
library(DiagrammeR)
Query1 <- dataset
Query1$LASTUPDATE <- as.POSIXct(Query1$LASTUPDATE, tz="GMT", format = c("%Y-%m-$d %H:%M:%S"))
x <- Query1 %>%
    eventlog(
        activity_id="STATUS",
        case_id="CONTRACTID",
        resource_id="PROJECT",
        activity_instance_id="INDEX",
        lifecycle_id="CONTRACTTYPE",
        timestamp="LASTUPDATE"
    ) %>% filter_endpoints(start_activities= "Draft", end_activities= "Expired")
y <- process_map(x, render=FALSE)
export_graph(y, "result.png", file_type = "png")

This is the visual being generated:

Thank you in advance for the help.
