Cannot get my e paper to work

g.drawString() still has issue, I removed setFontVector(), the text still can not display on the right side of display. but the g.drawCircle() function works well.
When I changed the g.setRotation() from 1 to 0, the whole display is working, but text is 90 degree rotated.

 function(err){
        // (optional) fill the internal buffer for all pixels with color white,
        // without this the default color will be black
        display.g.clear(0xFF);
        // not optional - rotate the display x and y coordinates 90 degrees to the right
        display.g.setRotation(0);
        // from here it shows the normal usage
        // set color black for subsequent uses
        display.g.setColor(0x00);
        // set fontsize, see Graphics and Fonts modules for further options
        display.g.setFontVector(12);
        display.g.drawString('Hello World!', 0, 10);
        display.g.drawString('Hello World!', 0, 50);
         display.g.drawString('Hello World!', 0, 100);
         display.g.drawString('Hello World!', 0, 140);
        display.g.drawCircle(40,40,30);
         display.g.drawCircle(40,100,30);
        display.g.drawCircle(40,140,30);
