javafx按钮点击后事件响应不完全

Question

给按钮绑定了一个生成javafx中折线图的时间，界面是通过fxml构建的所以时间也是用fxml绑定的。在第一次点击按钮之后，显示的图表并不完整，横坐标的值显示不完整，绑定的node也没有显示出来，再次点击之后才能显示。
如图，这是第一次点击：
再次点击过后：
用于构建折线图的数据没有变动过。
下面是这个方法的代码：
public void setChart(StockCondition sc1,StockCondition sc2){
Close.getData().clear();
log.getData().clear();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
DecimalFormat df2 = new DecimalFormat("######0.00000000");

    Name1.setText(sc1.getName());
    High1.setText(String.valueOf(sc1.getPeak()));
    Low1.setText(String.valueOf(sc1.getValley()));
    Log1.setText(df2.format(sc1.getProfit2()));
    Name2.setText(sc2.getName());
    High2.setText(String.valueOf(sc2.getPeak()));
    Low2.setText(String.valueOf(sc2.getValley()));
    Log2.setText(df2.format(sc2.getProfit2()));
