java - How to avoid negative values with JFreeChart fixed auto range -

I have a Geoffrey Chat Line plot that is dynamically with a data point for every move of my algorithm Update is Because the number of data points can be very large, I have used the method on the domain axis. This restricts the graph to display recent iterations (200 in my case).

It works well in 200 iterations beforehand. The problem is that, unless there are up to 200 iterations, negative values ​​are included in the axis (for example, after 50 iterations, ranges from -150 to 50). Negative iterations do not make sense. I would like to start the axis rather than negative values ​​at zero. How can I get it?

I do not think the pivot starts from 0 to 200 (the right-hand part of the plot is left empty until the plot fills it) or it's 0 to 1 (So ​​that the plot is always spread across the entire width of the chart)

I have tried:

• Calling does not play well with setFixedAutoRange.
• Calling does not matter.

Any thoughts?

It seems that you are looking for a solution in which the GeFree chart is manually Instead of setting it is configured to do for you.

I can not help with it ....

  while (production data) {/ p> 
 you can do something like this (for pseudo-code Sorry for):  
  this.produceData (); If (! Subdata buttons.Selected ()) {domainAxis.setRange ((calculated & lt; 200)? 0: count-200), counting; } And {domainAxis.setRange (0, count); }}  
 
 If I wanted to convert to a Pearl-encode word, then I would write it like this, just smile hard to read it: p 
 
  While (ProductData) {this.produceData (); DomainAxis.setRange ((((calculations & lt; 200) || All data buttons. Systèd ())? 0: count-200, counting); }
