LogAxis setRange() function sends me into memory error

Below is code that sends me into a memory error. I tried calling a simple setRange() function for the LogAxis class. It is important to note that I have never gotten a memory error like this before when working with any sort of axis, except this one. Here is the error: Exception in thread "AWT-Event...

Ok, I've tried playing around with LogAxis. I'm not sure if anyone else is running into the problems I have with it. Right now, everytime I manually call setRange() or setRangeWithMargins(). I don't know if any other method is affected. I always run into an out of memory for heap error. I have never...

Which version of JFree is LogAxis on? It seems to be experimental in mine. Is there any particular reason why a new LogAxis class was created and some things seem to be different from LogarithmicAxis?

Reference/Legend box INSIDE the plot?

Hi There. Is it possible to add a box/reference/legend frame on the plot itself and not as a legend item below the plot? If there is a quick fix for this, how can I do it? Thanks. Example of a chart I have on a different charting API is given below. Notice the mean/stddev/etc box in the upper left o...

Small Fractions on Log Charts

I am having problems in displaying negative exponent values for very small fractions on my Logarithmic Axis. 1, 10, 100.... all display correctly. I run into problems when I try to display 1/10, 1/100, etc. I want these to display as: 1e-1, 1e-2, 1e-3, etc. Is there a function I need to call to hand...

multiple colors on one series on line chart

Lets say I just have a single line chart with values: {-5, -4, -3, -2, -1, 0, 1 , 2, 3, 4, 5}. I just want ONE single line to appear on my plot, but all data points corresponding to negative numbers have 1 color, the data point corresponding to 0 has another color, and all positive data points have ...

chart NumberAxis problem

I'm getting a weird error on my NumberAxis. Lets say if all the numbers in the input dataset are the same, and I try to standardize my NumberAxis, then this happens. What am I doing wrong, and how can I fix it? In this case, the input to the dataset is a List of Double values all equal to 100. Numbe...

Adding permanent/anchor horizontal lines on chart

Hi. How do I add permanent horizontal lines on a chart? For example, if I want a solid horizontal line where Y=3 and Y=-3, where the X-value doesn't have any bearing. The lines also would not have a separate legend from all the other series lines. How do I do this?

Thanks ahead.

Chart X and/or Y-axis

For some of the charts I am creating, when the values become very small (i.e. xxxE-9, xxxE-12) the scaling on the charts vanishes. Boxes/lines/etc are plotted correctly in the picture, the axis labels vanish. Is there some way in jfreechart to make the domain/number axis and/or the renderer handle r...

Overlay multiple box plots?

Hi There. I am pretty new to JFreeChart, and would need some help in something I have to implement. In a nutshell, I have to create a chart with multiple box-and-whisker plots overlayed on a single X and Y axis. The only demo I've seen so far of a box plot is: JFreeChartBoxAndWhiskerDemo.htm This do...
