Graph is not showing - javafx

Question

I have a program that inputs data into a table, computes other data, then graph it afterwards. The table and the data shows properly, but the linechart shows nothing. Im using JavaFXML application and scenebuilder.
PS: I'm new at JAVA.

Answer 1

One of your datapoints is giving a NaN x-value, which is causing the auto-range of the number axis to fail. You can see this if you provide a little logging in your button handling method:
for(int i=0; i<9; i++)
{
XYChart.Data<Number, Number> dataPoint = new XYChart.Data<>(Math.log10(s[i]), Math.log10(us[i]));
System.out.println("("+dataPoint.getXValue()+", "+dataPoint.getYValue()+")");
graph.getData().add(dataPoint);
}
You can fix the problem by checking the value before adding to the chart:
for(int i=0; i<9; i++)
{
XYChart.Data<Number, Number> dataPoint = new XYChart.Data<>(Math.log10(s[i]), Math.log10(us[i]));
System.out.println("("+dataPoint.getXValue()+", "+dataPoint.getYValue()+")");
if (Double.isFinite(dataPoint.getXValue().doubleValue())) {
graph.getData().add(dataPoint);
}
}
