Re: How to implement Linear-Logarithmic axis (split axis)?

Hello Omri, This class is part of the JFreeChartCustom module in the Glotaran project currently hosted on kenai.com . Specifically it is implemented in the LinLogAxis.java class. For the number formatting I use a custom class: LinLogFormat.java . Please note that I cannot guarantee that the current ...

Re: problem with jfree library..

It seems to me you are missing the JCommon library. Much of the JFreeChart code depends on this library and it will not compile without.

Re: Zoom problem

The problem is that you are using a CategoryPlot which uses the CategoryAxis (or CategoryAxis3D in your case) for it's domain axis, and this class does not support zooming. You can only zoom in on the range axis because this uses the NumberAxis class, which does support zooming. So what you are expe...

Re: Zoom problem

It's not that people don't read your post, or don't want to reply, but without some reproducible example code nobody will be able to have any idea what the problem in your particular case might be. And then what should they write? Please refer to: [*] How to Ask a Question About JFreeChart - READ TH...

Re: zoom in another window

Your question is a bit unclear: Do you want to retrieve some information from tab 1 in order to create the chart in tab 2 (like for instance the Chart title). This you could do by simple calling getChart().getTitle().getText() for instance, and then you could even append the zoom range to the title ...

Re: zoom in another window

Maybe you could give us an example of how you are trying to implement this? Just a few lines of code can be helpful to see how far along you are. Basically, when you zoom, at some point methods like zoomRangeAxis and zoomDomainAxis (don't pin me down on the exact names, I did not look it up) are cal...

Re: plot graph extracting data from text file

You have 2 completely independent problems here: 1) Read values from a text file, interpret them as Java native variables (Integers, Doubles, etc) and put them into a format that can be converted into JFreeChart's internal data structure. ( how to do this? ) 2) Use JFreeChart to plot the converted d...

Re: How to put the Label of my TickLabels in exponential format

You should not be formatting the number before you add them to the chart, you Axis class should be formatting them. If you do not like the default formatting you can override the default numberformat by callling the axis setNUmberFormatOverride method, like this: NumberAxis xAxis = new NumberAxis();...

Re: How to implement Linear-Logarithmic axis (split axis)?

I guess it's time for me to finally get back at this post from a few years ago. From the lack of responses I guess that something like a Linear-Logarithmic axis is not the most popular of features. However, in the particular branch of science I'm involved in - analysis of time-resolved spectroscopy ...

Re: Setting unveven intervals in chart range axis

You would have to create your own implementation of ValuesAxis in order to achieve this. I assume you want the axis space between 1 and 2 to be the same as between 25 and 50, right? I am working on something that would come close to this kind of functionality. It will be a linear-logarithmic axis, w...

Re: Proposing 3d lib for extending Jfree capabilities

This looks amazing! It would be truly great if this library could be integrated into JFreeChart.

Any progress?

Did you ever write that renderer or did you find an alternative solution? I'm currently looking into plotting a 512*512=262144 points XYPlot using XYBlockRenderer and in the near future even 1024x1024=1M points. The draw times are already several seconds on a fast CPU whereas I would like it to be <...

thanks!

Thank you for pointing that out, I'm not fammiliar with the official Java-Language Standard so I didn't know it was a bogus warning. :)

I guess I will just suppress the warning using the

Code: Select all

-J-Dorg.netbeans.ProxyClassLoader.level=1000
command line switch, as pointed out in the link I gave earlier.
