                    }
                },

                    bar: { groupWidth: "90%" }
                  };
        var chart = new google.charts.Bar(document.getElementById('top_x_div'));
        chart.draw(data, options);
};

您需要在vAxis选项上设置viewWindow。

vAxis: {
    viewWindow: {
        min: 0
    }
}
