MLR3中的Expand_range参数用于可视化QDA

因此，我试图使用R中的MLR3VIZ包装来使R. Vizualisation（通过Plot_learner_prediction）中的MLR3VIZ包装进行验证，但是每次我尝试通过Expand_Range属性扩展预测范围时，都没有任何发生。

pl = plot_learner_prediction(learner, task, expand_range = 3)

当我添加或更改Expand_Range参数时，什么都不会发生。有人知道如何处理这个论点吗？我研究了文档 https://mlr3viz.mlr-org.com/reference> /plot_learner_prediction.html ，但这并没有真正的帮助。

已经非常感谢！

so I am trying to vizualize the prediction of an QDA-learner using the mlr3viz-package in R. The vizualisation (via plot_learner_prediction) works fine, however everytime I try to expand the range of the predictions via the expand_range attribute nothing happens.

pl = plot_learner_prediction(learner, task, expand_range = 3)

Nothing happens when I add or change the expand_range argument. Does anyone know how to handle this argument? I had a look into the documentation https://mlr3viz.mlr-org.com/reference/plot_learner_prediction.html but it doesn't really help me.

Thanks a lot already!
