Nodes going out of the visible area

[sukhwinderkaur1389]

Hi On load of saved json , nodes going out of the visible area of drawflow.

Can you suggest some solution?

While I looked into the json - pos_x, pos_y are in -ve value.

how to allow only visible nodes only?

@gocarlos - Can you please look into this issue?

Before importing you can always transform the position of your nodes.

Or you can also look at going to the position once imported, for example with the function:

[jerosoler]

Is a function. You have call.

[sukhwinderkaur1389]

Didn't get you ? I have called it call editor object.

[jerosoler]

editor.import(YOUR_DATA)
editor.translate_to(YOUR_POS_X, YOUR_POS_Y)

Example of use:

    var id = document.getElementById("drawflow");
    const editor = new Drawflow(id);
    editor.translate_to = function(x,y, zoom){
      this.canvas_x = x;
      this.canvas_y = y;
      let storedZoom = zoom;
      this.zoom = 1;
      this.precanvas.style.transform = "translate("+this.canvas_x+"px, "+this.canvas_y+"px) scale("+this.zoom+")";
      this.zoom = storedZoom;
      this.zoom_last_value = 1;
      this.zoom_refresh();
    }
    editor.start();

@jerosoler - Thanks for reply.

Its working fine.

One of the concern is that some of nodes are fine, this effect that nodes as well and nodes are going out of window again.

Issue I noticed that while clicked on zoom in then saving json then nodes going out of window.

Can't we get the visible corner pos_x , pos_y and load the nodes from there?

You can loop through the json before importing and get the positions values.
