Line and XYBar
I have three timeseries being display on a plot. I want two of them to be displayed as lines and the other as bars. I have tried setting the renderers like this XYItemRenderer[] renderers = getRenderes(); xyPlot.setRenderers(renderers); where the method getRenderes() has this code public XYItemRende...

Change color in a timeseries
I am plotting a time series line and would like to change its color depending on the value that I am plotting. For instance, if my values are negative I'd like it to be red, otherwise blue. How can I do that? With the renderer?
Thanks!
Thanks!

Time series gap
I am plotting 5-minute intraday stock data. I am using a TimeSeries like this new TimeSeries("Close",Minute.class); I use the Minute class (if not a good idea, please, let me know). When I display several days of data it shows up with a gap (actually a straight line) in between the minutes for which...

Never mind, I figured it out. There is a constructor to indicate the type of time data to pass to the class like this
Code: Select all
new TimeSeries("Price",Minute.class);

Error in timeseries
I am feeding a time series with data from intra-day, 5-minute futures. The data goes from 8:00 am to 3:10 pm. I pull the data from a database and try to add to the time series like this TimeSeries close = new TimeSeries("Close"); Connection conn = this.getConnection(); String sql = "SELECT * FROM fi...

Time in Dynamic Chart
In the project we are working on, we use artificial intelligence to predict movements at time + 1. In other words, whatever data we have at 8:00 am will be used to predict what we will have at 9:00 am (people who works with stocks may be very familiar with this). Anyway, we have a dynamic chart disp...

Dynamic Chart question
Is there anyway to start adding values to a dynamic chart from left to right instead of right to left as it is in all the examples?
Thanks!
Thanks!

Linear Regression Slope Graph
I need to create a Linear Regression Slope plot. My client wants the line to change color (from green to red and vice versa) when it changes directions. How do I do that? Any ideas?

This question is for blutfink. How did you make your x axis come out like that? With all the values less than 0 showing up on the tick labels and the vertical lines for those values also there? See, I have a log plot with values between 0.001 and 1 and I only get those two values on my plot and noth...

Log plot scale
I have a log-log plot and on my X axis I have a the scale set from 0.001 to 1. Now, I only see these two numbers and nothing else in between. My client would like to see some other markers (0.01, 0.1, etc). How can I make it do that?
Thanks!
Thanks!
