    public void setLabelHeight(int height) {
        utils.setLabelHeight(this, height);
    }
    public int getLabelHeight() {
        return utils.getLabelHeight();
    }
    public void setLabelDistance(int distance) {
        utils.setLabelDistance(this, distance);
    }
    public int getLabelDistance() {
        return utils.getLabelDistance();
    }
    public boolean isLabelVisual() {
        return utils.isLabelVisual();
    }
    public void setLabelVisual(boolean enable) {
        utils.setLabelVisual(this, enable);
    }
    public int getLabelOrientation() {
        return utils.getLabelOrientation();
    }
    public void setLabelOrientation(int orientation) {
        utils.setLabelOrientation(this, orientation);
    }
    public int getLabelTextColor() {

    }
    public void setLabelBackgroundColor(int backgroundColor) {
        utils.setLabelBackgroundColor(this, backgroundColor);
    }
    public String getLabelText() {
        return utils.getLabelText();
    }
    public void setLabelText(String text) {
        utils.setLabelText(this, text);
    }
    public int getLabelTextSize() {
        return utils.getLabelTextSize();
    }
    public void setLabelTextSize(int textSize) {
        utils.setLabelTextSize(this, textSize);
