Hi, I'm sorry for the delay.

The problem is that you have to set the justification of the labels. What
I do in SG is the following:

  switch(the_axis){
    case 0:
     if(axis->labels_attr.angle == 90 ||
        axis->labels_attr.angle == 270)
                axis->labels_attr.justification = GTK_JUSTIFY_CENTER;
     if(axis->labels_attr.angle == 0)
                axis->labels_attr.justification = GTK_JUSTIFY_RIGHT;
     if(axis->labels_attr.angle == 180)
                axis->labels_attr.justification = GTK_JUSTIFY_LEFT;
     break;
    case 1:
     if(axis->labels_attr.angle == 90 ||
        axis->labels_attr.angle == 270)
                axis->labels_attr.justification = GTK_JUSTIFY_CENTER;
     if(axis->labels_attr.angle == 0)
                axis->labels_attr.justification = GTK_JUSTIFY_LEFT;
     if(axis->labels_attr.angle == 180)
                axis->labels_attr.justification = GTK_JUSTIFY_RIGHT;
     break;
    case 2:
     if(axis->labels_attr.angle == 0 ||
        axis->labels_attr.angle == 180)
                axis->labels_attr.justification = GTK_JUSTIFY_CENTER;
     if(axis->labels_attr.angle == 90)
                axis->labels_attr.justification = GTK_JUSTIFY_LEFT;
     if(axis->labels_attr.angle == 270)
                axis->labels_attr.justification = GTK_JUSTIFY_RIGHT;
     break;
    case 3:
     if(axis->labels_attr.angle == 0 ||
        axis->labels_attr.angle == 180)
                axis->labels_attr.justification = GTK_JUSTIFY_CENTER;
     if(axis->labels_attr.angle == 90)
                axis->labels_attr.justification = GTK_JUSTIFY_RIGHT;
     if(axis->labels_attr.angle == 270)
                axis->labels_attr.justification = GTK_JUSTIFY_LEFT;
  }

You can also play with axis->labels_offset (distance to the axis).

The titles position is in 
axis->title.x/y
 
I'm going to add methods to tha API to handle this.
