How can I print the content of a dictionary of dictionaries?

labels is a dictionary of dictionaries :

{"1":{"id":"1","image":"1-0.png","name":"","xMax":"4802","xMin":"4770","yMax":"156","yMin":"141"},"2":{"id":"2","image":"1-0.png","name":"","xMax":"4895","xMin":"4810","yMax":"157","yMin":"141"},"3":{"id":"3","image":"1-0.png","name":"","xMax":"4923","xMin":"4903","yMax":"156","yMin":"145"},"4":{"id":"4","image":"1-0.png","name":"","xMax":"4956","xMin":"4931","yMax":"156","yMin":"145"}}

what I want is :

for (i = 0; i < labels.length; i++){
    drawLabels(
      labels[i].id,
      labels[i].xMin,
      labels[i].xMax,
      labels[i].yMin,
      labels[i].yMax
    );
  }

I have 4 dictionaries in the main dictionary so I want their content used 1 by 1 but labels.length isn't working not even the way I'm accessing my dictionary elements below.

How can I fix my code to do so?

labels isn't an array.

You should do it like this : 

for (let i in labels){
    if(labels.hasOwnProperty(i)) {
        drawLabels(
            labels[i].id,
            labels[i].xMin,
            labels[i].xMax,
            labels[i].yMin,
            labels[i].yMax
        );
     }
}
