echarts柱状图x轴字体显示不全问题

this.chart = echarts.init(document.getElementById(id));
              this.chart.showLoading();
              this.chart.setOption({
                  title: {
                      text: '产品线统计',
                      textStyle: {
                          fontSize:18,

              });
              this.chart.hideLoading()
          }
