hi, oops, sorry, i pasted the wrong code segment. sorry about that; this is what i have for that particular graph that i am after: BasicStroke stroke = new BasicStroke(3f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND); XYAreaRenderer2 xyrenderer = new XYAreaRenderer2(); xyrenderer.setSeriesPaint(0, Color.blue); xyrenderer.setStroke(stroke, true ); xyrenderer.setSeriesStroke(0, stroke, true); // System.out.println(BasicStroke.JOIN_ROUND + "," + BasicStroke.CAP_BUTT); // System.out.println( ((BasicStroke)(xyrenderer.getSeriesStroke(0))).getEndCap() ); plot.setRenderer(xyrenderer); thank you in advance ... ... |

Hi If anyone would have suggestions on how I can customize my tooltip text on my timeseries chart, it would be great. I am now showing the date (x-axis info) and the y-axis number. Instead I want to show an event number and the y-axis number. The event number is kind of like a counter. How do I pass this event ... |
I would like to make a graph that display the points in different colors depending on value. Is that possible.

I have been subclassing the ... |

I made a TimeSeriesChart with several series in a series collection. Now I'm tring to work with one plot and two different types of Renderers (XYAreaRenderer, XYItemRenderer) to show areas in the background and two lines in the front.

Hi all, iam a little confused how to set marking Points on lines. My Problem is that i have special values at my TimeSeries, as example y:=3 x:=03.07.2006 is a special point and should be marked, with a point or something else. the next point y:=2 x:=04.07.2006 is not a special-point - so it shouldnt get a mark. Now i've done ... |

Hello, I am trying to create a TimeSeriesChart. on the x-axis it's a daily values, while on the y-axis a simple floats values. my dataset does not contains weekend and holidays, but the line chart I get all the range of dates between the first and the last day on the dataset for example : (22/10/06, 560.5) (23/10/06, 570.5) (24/10/06, 565) ... |
Hi, I have a chart created with ChartFactory.createTimeSeriesChart() with the tooltip argument at true. The tooltips of the first dataset displays perfectly. Then i add another axis for a second dataset with a standardXYItemRenderer. I set the tooltipGenerator of the renderer to show the X and Y values, but the tooltips give me a strange number for the X (the date). ... |
Hi all. I'd like to create custom item labels for TimeSeriesChart by extending StandardXYItemLabelGenerator and overriding generateLabel method but my generateLabel method isn't called during chart creation. getItemLabelGenerator(int series, int item) shows that myStandardXYItemLabelGenerator is propperly set for each item. So what am I doing wrong / missing ? Why generateLabel() in myStandardXYItemLabelGenerator isn't called ? Code: Select all static class ... |
You can use the NumberAxis class of JFreeChart with NumberFormat for Y axis to format the values as desired and also DateAxis class of JFreeChart with SimpleDateFormat to format the value of X axis Let's take an example below: 2/ private void buildRangeAxis(JFreeChart chart) { XYPlot plot = chart.getXYPlot(); ValueAxis valueAxis = plot.getRangeAxis(); if (valueAxis instanceof NumberAxis) { NumberAxis axis = ... |
Hi all. I need to create a TimeSeriesChart to have on the x-axis a full minute time interval separated by seconds. This view will be refreshed every second. So at every second the view must move on the left and refresh its plot. I'm a newbie regarding the jfreechart, so in any case every help would be really appreciated. PS: if ... |

Hello, I am using a TimeSeriesChart. The sampling period of my data is eighth a second. And so I would like my domainAxis to be sampled each eighth a second. For example, when I use timeAxis.java2DToValue(), I want to get an eighth a second x value and not a millisecond x value. I thank about some possibilities : - to define ... |
Hi, I am using a dynamic TimeSeriesChart Whenever I update the chart with timeSeries.addOrUpdate(second, y); the chart grabs focus even when the window is in the background. So it makes it impossible to use any other program when the chart is updating. However if I minimize the chart this behavior stops. Is there a way of disabling the focus grab for ... |
I am using the ChartUtilities class to write my chart as a JPEG image. No matter what I set the width to, the last x value keeps getting clipped on the right side. Is there anyway to put a margin or padding around the chart, title, and axis to prevent this overflow? Thanks. |

I am seeing a problem where if a point is graphed on the right or lower border of my time series chart then the tooltip is not generated. The hotspot for the tooltip is not even graphed. I've looked in the source code a little and I noticed that in XYPlot these points are not considered visible so since processVisibleItemsOnly on ... |

I'm displaying some data in a time series chart. I display variable amounts of data, sometimes graph contains data for one hour, sometimes 24h. Behavior of ticks varies, graphs for longer periods are ok but graphs for a shorter time display wrong ticks. I'm using the "auto ticks" (by default) which alters the number of ticks and the "resolution" based on ... |

Hi all! I have the requirement to visualize special measurement values. Those values have timestamps that only consist of partial date/time information like "01:00" (no day). For an explanation of partial date/time see the Joda Time project. The values are calculated by building the diurnal variation (i hope that's the correct English word). Easiest way to explain this is probably an ... |

Greetings, I've been working on a project for a while now and generated a TimeSeriesChart with multiple series. These series get added and removed during the runtime.

If a renderer renders a data item of a series, and the paint for the series has not yet been specified, the renderer will ask a "drawing supplier" for the next paint (check AbstractRenderer.lookupSeriesPaint(int series) which is calling the abstract method getDrawingSupplier()). A renderer extending AbstractXYItemRenderer will return the DrawingSupplier of the XYPlot (see AbstractXYItemRenderer.getDrawingSupplier()) . By default, an XYPlot uses ... |
Sweepee, I don't know the JFreeChart... but I presume the TimeSeries.add method accepts a date, and time, or a datetime... check the API doco for it. ...also, It's not obvious where you're retrieving date/time's from the DB ... so are you sure you're retrieving a datetime (or a date and a time)... and not just a date?
