I want to specify and get the date of absolute calender of 7days selected to title each 7 graphs even though I get no response and a graph has no data. Therefore I want to know which date user picked on Dashboard Time filter.

Or if there is a way to make the x-axis and y-axis invisible when the graph has nothing to show. For example the graph under below has no values, but the x and y axis have been still shown.

I'm not sure you can access current time filter values outside of the `data` section, but you could hide the axis. The easiest way would probably be to set all `...Opacity` values to 0 using a signal -- so if there is no data (you can use `data('...')` expression for that, set it to `0`, otherwise set it to `1`. (see [axis](https://vega.github.io/vega/docs/axes/) docs):

```auto
"axes": [
  {
    "orient": "bottom",
    "scale": "x",
    "encode": {
      "domain": {
        "update": {
          "strokeOpacity": {"signal": "length(data('my-data-source')) == 0 ? 0 : 1"}
      },
...

```
