title: how can I manage a scatterChar in the javaFX from scene builder?
body: <p>I know how to manage the <code>scatter chart</code> inside the <code>start method</code>, but I want to use a <code>fxml</code> file containing a scatter chart and then I want to use a controller to control that. I used <code>Scenebuilder</code> for this purpose, but I don't know how I can add category axis to the <code>scatterChar</code>, I found the numeric Axis, but I didn't see any category axis to add.There is a horizontal category axis in the scene builder that is with the scatter chart, but I don't know, how I can add some values to it. Is that possible inside the scene builder, or I must do it in the controller?</p>
