Hello,

I have created a saneky diagram using the ggalluvial package. I would like the y-axis to have a scale from 0 - x number of children but haven't been able to work out how to do this. Any help would be much appreciated.

I have created an example dataset (below) and this is the code I have used to generate the plot (image below):

#load libraries

```
library(ggalluvial)
```

#load data and check uploaded correctly

```
data <- read.csv("file_location/gal_example.csv", header = T)
head(data)
```

#change order of levels

```
levels(data$result)
data$result<-factor(data$result, level = c('3','2','1','0'), order = TRUE)
levels(data$result)
```

#create plot

```
plot <- ggplot(data, aes(x = as.factor(year), stratum = result, alluvium = as.factor(id), fill = result, label = result)) + geom_flow() + geom_stratum(alpha = .5) + theme(legend.position = "none") + theme_minimal() + scale_x_discrete(name = "Year") + scale_y_discrete(name = "Number of Children")
plot
```

This is the data contained in the gal_example.csv file:

(so for example I have 26 children here and would be looking for a scale of 0 - 30 on the y axis of the above graph).
