Re: very weird frame updating issue

Yep

that was it,

Java event handlers must execute in a somewhat restrictive way. the charts would not update until the event handler was finished. I wrapped the instantiation of the chart and the subsequent data updates into a threat and it worked beautifully.

thanks.

Re: very weird frame updating issue

also, note that it's not just the charts that don't display, but also some of the other panels that hold various JLabels and JTextFields. basically, it just a blank frame.
this seems to suggest this is a java issue not a JFreeChart one. Hopefully someone ran into this before and has a way around it.

Re: Advice needed

Here check these out You should be able to use the overlaid example as your skeleton http://www.java2s.com/Code/Java/Chart/JFreeChartOverlaidBarChartDemo.htm Then you just need to replace the bar graph with an area data series and renderer as you can see here. http://www.java2s.com/Code/Java/Chart/J...

Re: Advice needed

Hi Yes you can create this graph. You just need to use two different data renderers. Use an area fill for the data series with the shaded in region, and use a standard line renderer for the other data sets. Your domain axis (x-axis) will likely need to be set up as a category plot since it not reall...

Re: Plots with large values (10^15+)

Hi everyone This was a great threat as I too have run into a similar issue. I am using Jfreechart version 1.0.16. I am trying to plot scatter chart with data in which the domain axis (X-axis) can have very large values; larger than 2^32, thus exceeding the capacity of float primitives. At first I wa...
