    Default JFreeChart XYLine

    Dear All,
    I am using JFreeChart to plot an XYLine using XYSeries.
    i.e:
    int i=0;
    XYSeries series=new XYSeries(temperature);
    series.add(i, Integer.parseInt(RTemp));

    instead of "i", I want to put a string such that the x-axis would display a string and y-axis would display an integer.
    so instead of :

    series.add(int, int);

    i want to have:
    series.add(string, int);

    How can i do it?
    Thank you

    I don't understand. XYSeries are supposed to be just that, with x and y numerical values. What sort of graph are you looking to create? Do you just want to change the X-axis display?

    That is, I want to display the patient's temperature (y-axis) at different times of the day and on different days(x-axis)

    See the following class to use as an alternative to an XYSeries:
    TimeSeries

    with the TimeSeries I managed to plot the date on the x-axis but not the date and time together. I converted the date i retrieve from the database into substrings:

    RDate=new String(RR.getString(2));
    n1=Integer.parseInt(RDate.substring(1,5));
    n2=Integer.parseInt(RDate.substring(6,8));
    n3=Integer.parseInt(RDate.substring(9,11));

    and then added it to the TimeSeries:

    s2.add(new Day(n1,n2,n3), Integer.parseInt(RTemp));

    Is there anything like TimeSeries or XYPlot that will allow me to plot (string s, int n)? so the x-axis arent values just names or strings and the y-axis are integers?
    Thank you very much for all the effort

    Try looking at setting the x-axis of the chart with a DateAxis. You can then work on getting the display you wish by setting the DateFormat for this object, formatting the said DateFormat the way you wish to display the data.

    I am trying to get an example on SymbolAxis. I think it may replace the date with a string on the X-axis. Do you know where i could find such examples? thank you
