JFreeChart AutoRange Doesn't Work on Multiple Series On The Same Plot

由 人盡茶涼 提交于 2021-01-28 06:34:23
问题 In this code I created 2 TimeSeries and added them to the same plot but the axis.setAutoRange(true) works only for the second series. Is there a way to make the AutoRange work on both of the TimeSeries? import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.ValueAxis; import org.jfree.chart.plot.XYPlot; import org.jfree.data.time.Millisecond; import org.jfree.data.time.TimeSeries; import org.jfree.data.time

JFreeChart advancing in time?

问题 I am making an application in which I need to show in a chart the real time of capturing a certain data And it "works" except that it doesn’t keep up with the real time, it keeps counting as if time has passed! I know that it is possibly linked to this dataset.advanceTime () but without it the graph becomes static and does not advance any more even if the real time passes package com.mycompany.moveplus; import java.awt.BorderLayout; import java.awt.Color; import java.awt.EventQueue; import

How to change/customize Crosshair Overlays for JFreeChart?

问题 I am trying to use a crosshair overlay for an XYPlot. This works quite well, though I would like to change the way the label is drawn. This is my current snippet: // add crosshair final CrosshairOverlay crosshairOverlay = new CrosshairOverlay(); final Crosshair xCrosshair = new Crosshair(Double.NaN, Color.DARK_GRAY, new BasicStroke(0f)); xCrosshair.setLabelBackgroundPaint(new Color(1f, 1f, 1f, 0f)); xCrosshair.setLabelOutlineVisible(false); xCrosshair.setLabelVisible(true); xCrosshair

问题 I want to connect X and Y coordinates by order which I inputed to make a circle . I found a program that draw X,Y coordinates in Java . Then I added my data of circle but program connected nearest X,Y coordinates not ordered X,Y . public Graph(final String title) { super(title); final XYSeries series = new XYSeries("Random Data"); series.add(2.000 , 0); series.add(0 , 2.000); series.add(-2.000 , 0); series.add(0 , -2.000); final XYSeriesCollection data = new XYSeriesCollection(series); final

In JFreeChart how to get the [x,y] values of a certain point on the chart?

问题 This question is related to my previous question [ How to display volume in the domain crosshair and set the crosshair programmatically? ], with the help of @trashgod, I got the answers for most of my questions, but one question is still unanswered, here I'll ask this question from a different angle. In my Swing app, there is a list of dates with some data, when I click on a certain date, I want my app to display a chart and points to that date when the image shows up, so I don't have to move

Delayed graph display when receiving data from BufferedReader

由 安稳与你 提交于 2021-01-05 11:26:09
问题 I have a very serious problem with JFreeChart . We wrote a program by C on the Tinker Board that takes the data from the ADXL355 sensor and displays it in shell. Then, with a program we wrote in Java, we received the data using a buffered reader and displayed it in graphs. There is no problem when we print the received data only in the output; but when we send the data to the graph for display, it is displayed with a delay of 30 seconds and this delay increases over time. We use JFrame form;

How can I integrate 2 different JFrames?

问题 I have a code ready that generates a CPU/Time chart (I changed another code according to my need). So far so good, but now I can't integrate it in a JFrame that is really mine and already stylized! Here is the code of the chart: /** @see https://stackoverflow.com/a/5048863/230513 */ public class Atol extends ApplicationFrame { private static final String TITLE = "Dynamic Series"; private static final String START = "Start"; private static final String STOP = "Stop"; private static final float
