# ===== for hyperSpec object ===============================================

labels(chondro)
labels(label_expr2text(chondro))

## Not run: \donttest{
# without `label_expr2text` labels with expressions are distorted or not plotted at all:

chondro[1:10,,] %>% qplotspc %>% ggplotly
}
## End(Not run)
# If function `label_expr2text` is applied:
chondro[1:10,,] %>% label_expr2text  %>% qplotspc %>% ggplotly


# ===== for ggplot2 object =================================================

chondro[1:10,,] %>% qplotspc %>% label_expr2text %>% ggplotly


# ===== for plotly object ==================================================

chondro[1:10,,]  %>% qplotspc %>%  ggplotly %>% label_expr2text
## Not run: \donttest{
## Does not work with newer version of `plotly`:
chondro[1:10,,]  %>% qplotspc %>%  ggplotly %>% plotly_build %>% label_expr2text
}
## End(Not run)
