I'm working with jfreechart-fx. I created a scroll panel and I have a ChartViewer (not a ChartPanel) inside of it. Inside the chart, I plot data using a CombinedDomainXYPlot. I add some data to the combined plot at runtime:
XYPlot subplot;
for (int i=0; i<10; i++){
dataset = .....
subplot = new XYPlot(dataset, null, rangeAxis1, renderer);
myCombinedPlot.add(subplot)
}
String panel_title = "bla bla";
myChartViewer.setChart(new JFreeChart(panel_title, JFreeChart.DEFAULT_TITLE_FONT, myCombinedPlot, false));
Now, when I drag and drop on my graph, I see that the default operation of mouse is the zoom on the signal. How do I disable this default function? I tried the following, but it doesn't work:
myChartViewer.getCanvas().setRangeZoomable(false);
myChartViewer.getCanvas().setDomainZoomable(false);
This behavior is controlled by an instance of ZoomHandlerFX installed by the ChartViewer constructor. To eliminate zooming entirely, simply remove the handler.
ChartViewer chartViewer = new ChartViewer(chart);
ChartCanvas canvas = chartViewer.getCanvas();
canvas.removeMouseHandler(canvas.getMouseHandler("zoom"));
If you later need to restore the handler, invoke addMouseHandler() like this:
canvas.addMouseHandler(new ZoomHandlerFX("zoom", chartViewer));

I have been using java 17 and I'm unable to add icons into the map as a layer. please help me.

I want to add a font-awesome icon to the map
Currently, your code is attempting to use an Icon as a Geometry in your feature. I'm guessing that's what isn't working since you don't say.
If you want to use an Icon to display the location of a Feature then you will need two things.
A valid geometry in your feature, probably a point (since an Icon is normally a point)
A valid Style to be used by the Renderer to draw your feature(s) on the map. Currently, you are asking for the line in your feature to be drawn using a yellow line (style5 = SLD.createLineStyle(Color.YELLOW, 2f);)
I can't really help with step 1, since I don't know where your fighter jet currently is.
For step 2 I suggest you look at the SLD resources to give you some clues of how the styling system works before going on the manual to see how GeoTools implements that.
Since you are trying to add an Icon I suggest you'd need something like:
List<GraphicalSymbol> symbols = new ArrayList<>();
symbols.add(sf.externalGraphic(svg, "svg", null)); // svg preferred
symbols.add(sf.externalGraphic(png, "png", null)); // png preferred
symbols.add(sf.mark(ff.literal("circle"), fill, stroke)); // simple circle backup plan
Expression opacity = null; // use default
Expression size = ff.literal(10);
Expression rotation = null; // use default
AnchorPoint anchor = null; // use default
Displacement displacement = null; // use default
// define a point symbolizer of a small circle
Graphic city = sf.graphic(symbols, opacity, size, rotation, anchor, displacement);
PointSymbolizer pointSymbolizer =
sf.pointSymbolizer("point", ff.property("the_geom"), null, null, city);
rule1.symbolizers().add(pointSymbolizer);
featureTypeStyle.rules().add(rule1);
But that assumes that you can convert your FontAwesomeIcon into a static representation that the renderer can draw (png, svg). If it doesn't work like that (I don't use JavaFX) then you may need to add a new MarkFactory to handle them.
I have the following LineChart in my FXML file:
<LineChart fx:id="line_chart">
<xAxis><CategoryAxis label="Time" /></xAxis>
<yAxis><NumberAxis label="Price" /></yAxis>
</LineChart>
In my controller file, I populate my series like the following code:
XYChart.Series<String,Number> series = new XYChart.Series<>();
DateFormat df = new SimpleDateFormat("yyyy/MM/dd");
for(int i = 0; i < lineChart_DATA.size(); i++)
series.getData().add(new XYChart.Data(df.format(lineChart_DATA.get(i).date),
lineChart_DATA.get(i).balance));
series.setName(GUISet.type);
line_chart.getData().add(series);
line_chart.setTitle("Title");
When I run my program, the X-axis only displays the last string value. I noticed that by running a second time the same code, the X-axis displays correctly.
Did I miss something in my code ?
I dont know if it is a specific bug or maybe I did not use LineChart properly but by disabling the animation of the LineChart, I was able to solve my issue.
line_chart.setAnimated(false);
I'm currently developing an android app for reading out multiple sensor values via Bluetooth and display them in a graph. When I stumbled upon jjoe64's GraphViewLibrary, I knew this would fit my purposes perfectly. But now I'm kind of stuck. Basically, I wrote a little function that would generate and display the values of three sensors in 3 different graphs one under the other. This works just fine when the activity is started first, all three graphs a nicely rendered and displayed. But when I want to update the graphs with different values using the resetData()-method to render the new values in each graph, only the last of the three graphs is updated. Obviously, because it's the last graph generated using this rather simple function. My question is: Is there any other elegant way to use a function like mine for generating and updating all three graphs one after the other? I already tried to set the GraphView variable back to null and different combinations of removing and adding the view. Passing the function a individual GraphView-variable like graphView1, graphView2... does also not work.
Here is the function:
private GraphView graphView;
private GraphViewSeries graphViewSerie;
private Boolean graphExisting = false;
...
public void makeGraphs (float[] valueArray, String heading, int graphId) {
String graphNumber = "graph"+graphId;
int resId = getResources().getIdentifier(graphNumber,"id", getPackageName());
LinearLayout layout = (LinearLayout) findViewById(resId);
int numElements = valueArray.length;
GraphViewData[] data = new GraphViewData[numElements];
for (int c = 0; c<numElements; c++) {
data[c] = new GraphViewData(c+1, valueArray[c]);
Log.i(tag, "GraphView Graph"+graphId+": ["+(c+1)+"] ["+valueArray[c]+"].");
}
if (!graphExisting) {
// init temperature series data
graphView = new LineGraphView(
this // context
, heading // heading
);
graphViewSerie = new GraphViewSeries(data);
graphView.addSeries(graphViewSerie);
((LineGraphView) graphView).setDrawBackground(true);
graphView.getGraphViewStyle().setNumHorizontalLabels(numElements);
graphView.getGraphViewStyle().setNumVerticalLabels(5);
graphView.getGraphViewStyle().setTextSize(10);
layout.addView(graphView);
}
else {
//graphViewSerie = new GraphViewSeries(data);
//graphViewSerie.resetData(data);
graphViewSerie.resetData(new GraphViewData[] {
new GraphViewData(1, 1.2f)
, new GraphViewData(2, 1.4f)
, new GraphViewData(2.5, 1.5f) // another frequency
, new GraphViewData(3, 1.7f)
, new GraphViewData(4, 1.3f)
, new GraphViewData(5, 1.0f)
});
}
And this is the function-call depending on an previously generated array (which is being monitored to be filled with the right values):
makeGraphs(graphData[0], "TempHistory", 1);
makeGraphs(graphData[1], "AirHistory", 2);
makeGraphs(graphData[2], "SensHistory", 3);
graphExisting = true;
Any help and / or any feedback in general is greatly appreciated! Lots of thanks in advance!
EDIT / UPDATE:
Thanks to jjoe64's answer I was able to modify the function to work properly. I was clearly having a mistake in my thinking, since I thought I'd also be changing a GraphViewSeries-object I would handle my function as additional parameter (which I tried before). Of course this does not work. However, with this minor Improvements I managed to make this work using a Graphviewseries Array. To give people struggling with a similar problem an idea of what I had to change, here the quick-and-dirty draft of the solution.
I just changed
private GraphViewSeries graphViewSerie;
to
private GraphViewSeries graphViewSerie[] = new GraphViewSeries[3];
and access the right Series using the already given parameter graphId within the function (if-clause) like this:
int graphIndex = graphId - 1;
graphViewSerie[graphIndex] = new GraphViewSeries(data);
In the else-clause I'm updating the series likewise by calling
graphViewSerie[graphIndex].resetData(data);
So, once again many thanks for your support, jjoe64. I'm sorry I wasn't able to update the question earlier, but I did not find time for it.
of course it is not working correct, because you save always the latest graphseries-object in the member graphViewSerie.
First you have to store the 3 different graphviewseries (maybe via array or map) and then you have to access the correct graphviewseries-object in the else clause.
I've ran into a weird problem with getCharBoundaries, I could not figure out what coordinate space the coordinates returned from the function was in. What ever I tried I could not get it to match up with what I expected.
So I made a new project and and added simple code to highlight the last charater in a textfield, and all of a sudden it worked fine. I then tried to copy over the TextField that had been causing me problems, into the new project. And now the same weird offset appeared 50px on the x axis. Everything else was spot on.
So after some headscracthing comparing the two TextFields, I simply can not see a difference in their properties or transformation.
So I was hoping that someone might now what property might affect the coordinates returned by getCharBoundaries.
I am using Flash CS4.
I've just had exactly the same problem and thought I'd help out by offering what my findings are. With a help from this thread, I tried to find everything that wasn't 'default' about the textfield I was using. I found that when I had switched my TextFormatAlign (or 'align' in the IDE) and TextFieldAutoSize properties to 'LEFT' as opposed to 'CENTER', it solved the problem.
A little late in the game perhaps, but worth knowing for anyone running into the same problem. This was the only thread I could find that raised the right flag...
Well the getCharBoundaries returns the boundaries in the textfield coordinate system. Where the origin is topleft corner of the textfield.
getCharBoundaries does not take into consideration the scrolling. you need to check if there are scrollbars on its parent (textarea) and if so relocate. One quick way of doing it is using localtoglobal and globaltolocal. Use the first to translate from the textfield coordinate system to the application coordinate system and then use the second to translate from the app coordinate system to the coordinate system of the parent of the textfield which is the textarea. I'm fine tuning a my method to get char boundaries i will publish it today on my blog

Works For Me(tm) (Flex Builder AS3 project):
[Embed(systemFont="Segoe UI", fontWeight="bold", fontName="emb",
mimeType="application/x-font")]
private var EmbeddedFont:Class;
public function ScratchAs3()
{
stage.scaleMode = 'noScale';
stage.align = 'tl';
var m:Matrix = new Matrix(.8, .1, -.1, 1.1, 26, 78);
var t:TextField = new TextField();
t.autoSize = 'left';
t.wordWrap = false;
t.embedFonts = true;
t.defaultTextFormat = new TextFormat("emb", 100, 0, true);
t.transform.matrix = m;
t.text = "TEST STRING.";
addChild(t);
var r:Rectangle = t.getCharBoundaries(8);
var tl:Point = m.transformPoint(r.topLeft);
var tr:Point = m.transformPoint(new Point(r.right, r.top));
var bl:Point = m.transformPoint(new Point(r.left, r.bottom));
var br:Point = m.transformPoint(r.bottomRight);
graphics.beginFill(0xFF, .6);
graphics.moveTo(tl.x, tl.y);
graphics.lineTo(tr.x, tr.y);
graphics.lineTo(br.x, br.y);
graphics.lineTo(bl.x, bl.y);
graphics.lineTo(tl.x, tl.y);
}
To literally answer your question, it returns the coordinates in the TextField's coordinate system, not it's parent, and it is affected by DisplayObject.transform.matrix, which is the backing for the .x, .y, .scaleX, .scaleY, .width, .height, and .rotation properties.
What ever it was the solution was simple to add a new TextField, never found out what property screwed everything up.
The first answer is correct in most cases. However if your field is parented to another movie clip it may still return the wrong y coordinate. try this code:
//if this doesn't work:
myTextFormat = new TextFormat();
myTextFormat.align = TextFormatAlign.LEFT;
myFieldsParent.myField.autoSize = TextFieldAutoSize.LEFT;
myFieldsParent.myField.setTextFormat( myTextFormat);
//try this:
var x = myFieldsParent.myField.getCharBoundaries(o).x;
var y = myFieldsParent.myField.getCharBoundaries(o).y;
var myPoint:Point = new Point(myField.getCharBoundaries(o).x,myField.getCharBoundaries(o).y);
var pt:Point = new Point(myFieldsParent.myField.getCharBoundaries(o).x, myFieldsParent.myField.getCharBoundaries(o).y);
pt = myFieldsParent.myField.localToGlobal(pt);
//pt is the variable containing the coordinates of the char in the stage's coordinate space. You may still need to offset it with a fixed value but it should be constant.
I didn't test this code as I have adapted this example from code that is embedded into my project so I apologize if I'm missing something...
I am creating a chart using mxml. The mxml tags only create a chart with a horizontal axis and vertical axis.
My result event handler has actionscript code that loops through the xml result set and creates all the series (line series and stacked bar). This part of the code works fine.
Now I need to use the functionfill function to set individual colors to each series. All the examples I have found call the functionfill from within an MXML tag, like so:
<mx:ColumnSeries id="salesGoalSeries"
xField="Name"
yField="SalesGoal"
fillFunction="myFillFunction"
displayName="Sales Goal">
I am having trouble calling functionfill from actionscript.
A portion of the code that build the data series is below:
if (node.attribute("ConfidenceStatus")=="Backlog"
|| node.attribute("ConfidenceStatus")=="Billings") {
// Create the new column series and set its properties.
var localSeries:ColumnSeries = new ColumnSeries();
localSeries.dataProvider = dataArray;
localSeries.yField = node.attribute("ConfidenceStatus");
localSeries.xField = "TimebyDay";
localSeries.displayName = node.attribute("ConfidenceStatus");
localSeries.setStyle("showDataEffect", ChangeEffect);
localSeries.fillFunction(setSeriesColor(xxx));
// Back up the current series on the chart.
var currentSeries:Array = chart.series;
// Add the new series to the current Array of series.
currentSeries.push(localSeries);
//Add Array of series to columnset
colSet.series.push(localSeries);
//assign columnset to chart
chart.series = [colSet];
My setSeriesColor function is:
private function setSeriesColor(element:ChartItem, index:Number):IFill {
var c:SolidColor = new SolidColor(0x00CC00);
var item:ColumnSeriesItem = ColumnSeriesItem(element);
//will put in logic here
return c;
}
What parameters do I put in the line localSeries.fillFunction(setSeriesColor(xxx)) ?
I tried localSeries as the first argument but I get an implicit coercion error telling me localSeries can't be cast as ChartItem.
How do I call the function correctly?
localSeries.fillFunction = setSeriesColor;
The code you have right now is actually CALLING setSeriesColor the way you have it set up. You only want it to refer to a reference of the function, not calling it, so just send it "setSeriesColor" as a variable.
