So 100k of data (100 Hz data update frequency, total time 1000 sec or 16 min) rendered as a line with a "visual update frequency" of 0.5 sec would be ok? If you mean that the 100k data points will be drawed within 0.5 secs. Then yes i think this would be ok for me. I'm not sure tho i would have to ...

Hi Paradox, Thanks for replying i'm going to give you the best explanation on those questions as possible. - What type of dataset and renderer are you using? From your post, I assume that the dataset might by an XYSeriesCollection or a TimeSeriesCollection. Indeed it's a XYSeriesCollection. Not a Ti...

Hi there, First of all thanks for reading trough my post. I already read the topic http://www.jfree.org/phpBB2/viewtopic.php?f=3&t=18592 . And i know they have similar problem and they solved it they say but i can't get the Fast classes implemented into my application and like the creator says. he h...

Dear paradoxoff, I'm very pleased of your effort to help me. But the only thing your telling me is saying what could be the problem. But i need a solution to solve this problem. what can i do about the .NaN double values. How can i get my auto range to work like intented? About the black dot series....

Yes i got 2 datasets, the black dot serie is a clone of the red line serie. I created this so i know where the point being drawn is. I set the draw shape boolean to true. this doesn't solve anything. double.NaN: i wouldn't think this is the problem? I only add doubles to the series. I even check bef...

I'm using XYSeries in a XYSeriesCollection and a XYLineAndShapeRenderer. I find it strange too. For the Y-axis it does it fine when i make it auto range trough user interaction is just goes from 0-3000 for examples if the highest value is 3000 in the data set. But for the X-axis it won't do it prope...

Hi, I wrote a java Swing application which draws a graph with incoming data through serialport connection. The first image shows the chart with a fixed X-axis range programmed in the software going from 0-5000. it has been set with the following piece of code: NumberAxis xAxis = (NumberAxis) plot.ge...

This example overrides the renderer's getItemShape() method to return a distinct Shape for a specific point. This example overrides the renderer's getItemPaint() method to return a distinct Paint for a specific point. Thanks for the reply. I also found those two examples but it wasn't really what i...

Hi there, in my chart i'm drawing the same graph all the time going forward and backward all the time. on my x-as the values go from 0-5000 and going back from 5000-0. The chart will draw the line almost identical the entire time. For me it's important that i can follow where the line is drawing. so...

Hi, First of all thanks for reading my post. I have an java swing application where I have panel with a chart on it. This chart made from the library JFreeChart displays a dynamic XYLineChart. My application gets data over a COM port. this data comes in approx. every 20ms. I save a time stamp for ev...
