Need some help upgrading from an ancient version (0.6.1)

[Shark812]

Sorry guys to bother, I'm writing because I'm having some issue upgrading from the version 0.6.1 (de.blox:graphview).

This is an example of one Android layout:

        <de.blox.graphview.GraphView
        android:id="@+id/graph"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="@dimen/activity_margin"
        app:hasClickableChildren="true"
        app:horizontalPanEnabled="false"
        app:lineColor="@android:color/white"
        app:lineThickness="8dp"
        app:useMaxSize="true"
        app:verticalPanEnabled="false"
        app:zoomEnabled="false" />

or this is an activity that is actually working:

        zoom.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (isZoom) {
                graphView.zoomTo(1.0f, true);
                graphView.setZoomEnabled(false);
                graphView.setVerticalPanEnabled(false);
                graphView.setHorizontalPanEnabled(false);
                //zoom.setBackgroundResource(R.drawable.zoom_in);
                isZoom = false;
            } else {
                graphView.zoomTo(2.0f, true);
                graphView.setZoomEnabled(true);
                graphView.setVerticalPanEnabled(true);
                graphView.setHorizontalPanEnabled(true);
                isZoom = true;
                //zoom.setBackgroundResource(R.drawable.zoom_out);
            }
        }
    });

I tried updating the library but I'm struggling with all the changes, can you guys just face me in the right direction?
Thanks for the great work!
