Re: Bug in Y Axis if I use AutoRange for X axis
regarding axisY.setFixedAutoRange(1); I played around with it if I start with a value of 445 at the beginning, the value will be displayed on the top, the lower value is 444 if the value decreases to 421 the plot is not visible any more We have a terminology problem here! In JFreeChart, a "plot" is...

Re: Bug in Y Axis if I use AutoRange for X axis
Now I tried axisY.setFixedAutoRange(1); this removed the xxE1 Values but now the plot is on the top and only the half width of the plot is visible (see screenshot) If you change the fixed-auto-range of the y-axis this should not effect the width of the plot (or the x-axis, i.e. the date) in any way...

Re: Bug in Y Axis if I use AutoRange for X axis
Hi Martin, I can not set a fixed Autorange for the Y axis because I am getting my data dynamically from a MySQL database, sometimes I have a value of 20 °C and sometimes a value of 450 Watt so if I set the range fixed to 500 I will see the plot for the temperature (of course in a different chart) a...

Re: Bug in Y Axis if I use AutoRange for X axis
Are you mixing up axes? The domain-axis is for x-values and the range-axis is for y-values. In your code you are setting the auto-range feature for x-axis (time) and this seems to work fine (I don't know the data, though). For the y-axis you are not settings anything, so I guess the auto-range featu...

Re: JFreeChart at GitHub
Hi David!
So what is the further plan? Do all modifications go to github from now on?
Should we put Sourceforge repo in read-only mode? Are we able to do this?
Or are you planing to sync those repos somehow?
Thank's for keeping us informed.

Re: Servlet Invoked Multiple Times For Each Request
This is off-topic, as JFreeChart is definitely not the component, triggering any Servlet request. The example you linked to, looks good for me. My guess is, that the HTML/JSP-page is somehow triggering the double request. What, if you enter the Image-URL in the browser? Does it still fire two reques...

Re: PolarPlot: Plots different after v1.0.13
Glad to hear it's working now! Removing rangeAxis.setInverted(true); fixed the problem I was having. So would say the current behavior with setInverted(true) is buggy? Or is it just not what you'd expect? If you'd call it a bug please describe the problem and expected behavior in more detail and fil...

Re: PolarPlot: Plots different after v1.0.13
Hi! Why are you using your own renderer? What is actually different to JFreeChart's DefaultPolarItemRenderer? Did you try the DefaultPolarItemRenderer? If yes, is there also a difference between the two JFreeChart versions? Your chart's do not contain any labeling and you did not set any explicit ra...

Limitations of DateTickUnit and suggestion for improvement
Hi all! I have a chart that uses a DateAxis . I can configure the DateAxis to only show ticks I want with the DateTickUnit class. Now, I want to create my tick labels with a user-defined format. I can set the formatter on construction time of my DateTickUnit objects. Unfortunately I have to pass an ...

Re: Why are not all the Bars in my Barchart red?
BarRenderer.setDefaultShadowsVisible(false)
Or the corresponding method if you are using a different renderer.

How did you zoom? Zoom the generated PNG?
You should create a PNG with higher resolution or zoom in your application.
