Incomplete display in Curve mode

Recommended Posts

Hi,

I am having some display issue when rendering a chart in curve mode: The line isn't painted in some cases. It seems the scale of the Y-axis is not well adjusted to draw the inferior part of the line.

Here is a simplified example that shows my problem:

import java.awt.Dimension;

import javax.swing.JFrame;

import com.softwarefx.chartfx.desktop.Chart;
import com.softwarefx.chartfx.desktop.Gallery;

public class Example {

  public static void main(String[] args) {
  Chart c = new Chart();
  double vals[] = { 0, 0, 0, 0, 0, 134.5, 269, 404 };
  c.getData().setPoints(vals.length);
  for(int i = 0; i < vals.length; i++) {
  c.getData().set(0, i, vals);
  }
  c.getData().setSeries(1);
  c.setGallery(Gallery.CURVE);

  JFrame frame = new JFrame();
  frame.getContentPane().add©;
  frame.setSize(new Dimension(800, 600));
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.setVisible(true);
  }
}

In this example, the line between points 4 and 5 is not drawn on screen since inferior to the minimum (although the y-axis is left to adjust according to values).

Is there a way to make sure the curve line is always completely displayed on screen without having to force the minimum (since my values change dynamically)?

Thanks for your help,

Shady
