II drew a 3D line chart using jfree.chart3d in the Orson Charts library using java. How can I get the data between two points selected with the mouse on the line chart I drew?

I searched deeply but get no getDataset() or similar methods in the library. I try to get the line plot at the clicked point with the mouse but found no such method. Any help would be appreciated. There are solutions on 2D charts but I have not come across such a solution for jfree.chart3d library

I try to read the dataSet among the line charts selected by mouse. First mouse click defines the start point of the sub-line, and second mouse click defines the end point of the sub-line of the line selected by mouse. I tried to read the dataSet as follows. But I get "getRenderer() is undefined for type Plot3D" error. Here are my questions:

1.How can I highlight the selected line plot, so that to create awareness to the user that he/she has chosen the right plot among other plots?

2.How can I get the selected line plot's dataSet?

3.How Can I obtain the sub-dataSet between two mouse clicks on the selected line plot?

There is a stackoverflow issue about that. Here is the link:

There are unresolved compilation problems in the download (java 1.8 compatability)
Here are the errors:

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
	The return types are incompatible for the inherited methods ColorScale.getRange(), AbstractColorScale.getRange()
	Type mismatch: cannot convert from org.jfree.data.Range to com.orsoncharts.Range
	The method percent(double) is undefined for the type Range

I think this is also causing the constructor to choke in the demo:
The constructor GradientColorScale(Range, Color, Color) is undefined

I use JFreeChart quite a bit and would like to now add 3d charts... thus hoping this project is active and well maintained :-) Cheers!

I am trying to figure out how to setup the following surface chart. Data is fft data
VectorvFrequencies; // y axis lables (frequency)
double[] dSingleRow; // each value is a frequency level
Vector<double[]> vAllRows; // each row is another time sample
Date is read in from a stream that is fft'ing a file, in csv it might look like:
Time, 100Hz, 200Hz, 300Hz....
1, -90, -89.4, -89...
2, -89.9, -88, -89.1...
...

I have attached a sample plot produced by gnuplot

Hi,

and here is another thing I wasn't able to achieve so far: Combine a SurfaceChart with a XYZLineChart in one chart.

Usage: My GPXEditor should show a gpx track (XYZLineChart) on top of the SRTM height data (SurfaceChart).

Again I'm failing to add a screenshot of how things should look like here :-( But hopefully, the idea is clear.

Any hints are appreciated!

Hi,

I was trying to change to format of the tick label using NumberAxis3D.setTickLabelFormatter - with no results. No matter what I set here the format is always the same.

When checking, how the formatter is used in the library I get

Usages of NumberAxis3D.getTickLabelFormatter [no occurrences]                

so it seems that this feature isn't used at all?

Hi,

first of all thanks for the great library!

I'm currently trying to switch from jzy3d because of better support for zoom & export in orson-charts. While converting my code I have run into something I wasn't able to achieve: I would want to hide the x-y grid lines that are drawn on the surface chart. (Probably something simple to fix but I can't seem to find the option...).

Will attach an image to cleare show what I mean - once I don't get any error when trying to add an attachment.

Thanks for any hints,
Thomas

Reported in the forum at jfree.org, the XYZSeries class has no method to remove items. It is also missing the event notification mechanism.

Hello and thanks for sharing this 3d Chart library :-)

In method axisChanged() of xyzPlot (line 682) we have :

public void axisChanged(Axis3DChangeEvent event) {
        this.yAxis.configureAsYAxis(this);
        fireChangeEvent(event.requiresWorldUpdate());
}

Shouldn't it be :

public void axisChanged(Axis3DChangeEvent event) {
    	if(xAxis == event.getAxis()) 
    		xAxis.configureAsXAxis(this);
    	if(yAxis == event.getAxis()) 
    		yAxis.configureAsYAxis(this);
    	if(zAxis == event.getAxis()) 
    		zAxis.configureAsZAxis(this);
        fireChangeEvent(event.requiresWorldUpdate());
}

This is actually what I've done and it solved bad axis range.
