The red box is something I took on internet…when you have “string” values to will able to show on the dash use that. In fact I dont know why.

I want to use this kind of block to show the 3 different values of this attribute by the time. Something like that…

The type of graph you’re building cannot be done using the built-in Time Series Block. It can, however, be done using the Custom Chart Block. Here’s an example:

The currentStatus attribute is a string, just like your example.

Here is the Vega configuration:

{
  "$schema": "https://vega.github.io/schema/vega-lite/v2.json",
  "width": {{block.width}},
  "height": {{block.height}},
  "autosize": {
    "type": "fit",
    "contains": "padding"
  },
	"data": {
    "name": "time-series-0"
  },
	"mark": {
    "type": "bar"
  },
  "config": {
    "axis": {
      "labels": false,
      "domain": false,
      "ticks": false,
      "grid": false
    },
    "view": {
    	"fill": "transparent",
      "stroke": "transparent"
    },
    "scale": {
      "bandPaddingInner": 0
    }
  },
  "encoding": {
    "x": {
      "field": "time",
      "type": "ordinal",
      "axis": null
    },
    "y": {
      "field": "value",
      "type": "ordinal",
      "scale": {
        "domain": []
      },
      "axis": null
    },
    "color": {
      "field": "value", "type": "ordinal",
      "legend": null,
      "scale": {
        "domain": ["alarm","cutting","notCutting","stopped"],
        "range": ["#BD0000","#8DB319","#29ABE2","#B3B3B3"]
      }
    }
  }
}

You’ll need to change the domain and range properties to match your string values and desired colors. Hopefully this helps point you in the right direction!
