How change objects color at visu

[admin]

Use this, make sure that all lower/upper limit objects are defined and they all follow the naming scheme as you've posted.

Code:

$(function() {
  $('.color-by-value').each(function(_, el) {
    var addr = $(el).data('object');
    if (addr) {
      grp.listen(addr, function(obj) {
        var value = obj.value;
        var name = obj.name;
        var color = 'green';
        var lname = name.replace('ACTUAL_TEMP', 'LOWER_LIMIT');
        var uname = name.replace('ACTUAL_TEMP', 'UPPER_LIMIT');
        var llimit = grp.getvalue(lname);
        var ulimit = grp.getvalue(uname);

        if (value < llimit) {
          color = 'blue';
        }
        else if (value > ulimit) {
          color = 'red';
        }

        $(el).css('color', color);
      });
    }
  });
});
