## Sync charts

With [Apexcharts](https://apexcharts.com) you can sync (tooltip, zoom) several charts together by providing a group and id to each charts. This works in Shiny and Markdown. Here an example where we create two charts, tooltip will be displayed on both charts when you hover one, and if you zoom on one, the other one will be synced :

```{r example-1, eval=FALSE}
apex(
  data = tail(economics, 150), 
  mapping = aes(x = date, y = pce),
  type = "line"
) %>% 
  ax_chart(
    group = "economics", id = "pce" # <- define common group and unique id
  )

apex(
  data = tail(economics, 150), 
  mapping = aes(x = date, y = psavert),
  type = "line"
) %>% 
  ax_chart(
    group = "economics", id = "psavert" # <- define common group and unique id
  )
```


```{r run-example-1, echo=FALSE, ref.label="example-1"}

```



## Brush chart

Create a brush chart to navigate into a synced chart : use the chart below to navigate in the chart above.

```{r example-2, eval=FALSE}
apex(
  data = economics, 
  mapping = aes(x = date, y = psavert),
  type = "line"
) %>% 
  ax_chart(
    id = "target-chart", # <-- define target id here
    toolbar = list(
      autoSelected = "pan",
      show = FALSE
    )
  )

apex(
  data = economics, 
  mapping = aes(x = date, y = psavert),
  type = "line", 
  height = "130px"
) %>% 
  ax_chart(
    brush = list(
      target = "target-chart", # <-- use target id here
      enabled = TRUE
    ),
    offsetY = -20,
    selection = list(
      enabled = TRUE, # <-- enable selection and define starting range
      xaxis = list(
        min = format_date(economics$date[1]),
        max = format_date(economics$date[100])
      )
    )
  ) %>% 
  ax_xaxis(labels = list(show = FALSE)) %>% 
  ax_yaxis(labels = list(show = FALSE))
```


```{r run-example-2, echo=FALSE, ref.label="example-2"}

```
