TChart serializable problem

Post by rubby » Sun Sep 22, 2013 7:28 am

hello,

I see that TChart implements Serializable.

Does it support to save TChart to a file and restore it form the file?

I mean:
if i have an instance
TChart chart = ...;
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("chart.dat"));
out.writeObject(chart);

//in another place

ObjectInputStream in = new ObjectInputStream(new FileInputStream("chart.dat"));
TChart chart2 = (TChart)in.readObject();

In this way, i can get the original TChart.
I have tried this.
but it fail.
Do you know how to solve this? thanks.

Hi rubby,

Yes, this is possible using TeeChart native template files (.tej in Java). You'll find more specific information in Tutorial 9. Exporting and Importing Charts. Tutorials can be found at the Docs folder in TeeChart's installation.

Hello,

Thanks.

But when I try one example of TeeChart for Swing, its path is All features-->Chart styples --> Bar --> Negative Stacked.
In the poped edit dialog, I export its template as xml format,

Some errors happen,

java.lang.NullPointerException
at com.steema.teechart.Aspect.getTextSmooth(Aspect.java:234)

Hi,

I've just run TeeChart.Features.jar from TeeChart Java Suite with SourceCode v3.2013.0517. I went to the "Negative Stacked" example, opened the editor, navigated to the "Export\Template" tab. Checked the "XML Format" checkbox and pressed "Save" button.
Find attached the xml generated. It looks correct.

Do you see any difference between what we are doing?

Hello, Yeray

I did not run it by the TeeChart.Features.jar.
I put the releated example code into netbeans, and run the example from netbeans.
in the output window of nebeans, some errors display.

I think even there is error, the TeeChart.Features.jar has no place to show it, because the error will be catched.

Thanks.

Hi,

Although I get a correct xml file, I get many errors with the Suite with Sources v3.2013.0517. Find the errors attached (I attached a text file because the string is too long for a post).
However, I don't get any error with the actual sources we have here, so they shouldn't appear in the next version.

yes. I encount similar errors too.
Because of them,
when i export TChart and import them then, it fails or some properties are not effected.

    }
}
1. tej xml problem
I store the Tchart to c:\\tt23.xml and c:\\tt23.tej. (Stored Chart.png)
But when i load c:\\tt23.xml, the X axix label is not "MyXLabel-2". (xml loaded.png)
when i load c:\\tt23.tej, the "Stored chart" does not showed. Nothing changed (tej loaded.png)

What's more, there are some errors in the IDE outp0ut. My IDE is netbeans.

2. i want to know how to calculate the correct position of label item. so "MyXLabel-1" and "MyXLabel-2" can be presented correctly.
"bottom.getLabels().getItems().add((double) 0, "MyXLabel-1");" // in fact i want to add "MyXLabel-1" as the first label


Thanks.

Re: TChart serializable problem

Hello rubby,

We've made some tests with the Swing features demo shipped with the installation, concretely with the example at "All features\Welcome!\Exporting\Native binary format".
- With NetBeans, create a "new project from existing sources" and use the features demo project at "Examples\Swing\Features\src\features"
- Open the project properties and make it use the TeeChart.Swing.jar at the Libraries menu.
- Change TemplateDemo.java with the following:

Code: Select all

    protected void initChart() {
        super.initChart();
        copyChart = new TChart();
        
        chart1.addSeries(new Bar());
        chart1.getSeries(0).add(1, 10);
        chart1.getSeries(0).add(2, 15);
        chart1.getSeries(0).setTitle("A series");

        chart1.addSeries(new Bar());
        chart1.getSeries(1).add(1, 20);
        chart1.getSeries(1).add(2, 35);
        chart1.getSeries(1).setTitle("Bseries");

        chart1.setText("Stored chart");
        chart1.getSeries(0).setTitle("StoreA");
        chart1.getSeries(1).setTitle("StoreB");
        Axis bottom = chart1.getAxes().getBottom();
        System.out.println(bottom.getLabels().getItems().size());
        bottom.getLabels().getItems().add((double) 0, "MyXLabel-1");
        bottom.getLabels().getItems().add((double) 1, "MyXLabel-2");
    }
It seems to work without problems:

It also shows the same good result if I change the code for the "run button" to use a tej file instead of a memory stream:

Code: Select all

    public void actionPerformed(ActionEvent ae) {
        Object source = ae.getSource();
        if (source == editButton) {
            ChartEditor.editChart(chart1.getChart());
        } else if (source == editButton2) {
            ChartEditor.editChart(copyChart.getChart());

        } else if (source == runButton) {            
            try {
                chart1.getExport().getTemplate().toFile("C:\\tmp\\serialiseTest.tej");
            } catch (FileNotFoundException ex) {
                Logger.getLogger(TemplateDemo.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IOException ex) {
                Logger.getLogger(TemplateDemo.class.getName()).log(Level.SEVERE, null, ex);
            }
            try {
                copyChart.setChart(copyChart.getImport().getTemplate().fromFile("C:\\tmp\\serialiseTest.tej"));
            } catch (FileNotFoundException ex) {
                Logger.getLogger(TemplateDemo.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IOException ex) {
                Logger.getLogger(TemplateDemo.class.getName()).log(Level.SEVERE, null, ex);
            } catch (ClassNotFoundException ex) {
                Logger.getLogger(TemplateDemo.class.getName()).log(Level.SEVERE, null, ex);
            }

            copyChart.refreshControl();
        }
    }
So, try adding the copyChart.refreshControl(); call after importing the tej file.
Also please check your project is referencing the correct jar and not a TeeChart.Swing.jar from a previous version.

Re: TChart serializable problem

Post by rubby » Tue Jan 21, 2014 3:37 pm

Hello, Yeray,

thank you sincerely for your reply.

1. I am sure that my project is referencing the correct jar, TeeChart.Swing.jar from directory TeeChartJavaSrc_3.2013.1219.
So it is the latest version. I have checked this several times.

2. your test is using the example at "All features\Welcome!\Exporting\Native binary format".
But "MyXLabel-1" is still not showed corrected. only "MyXLabel-2" is showed.

3. Yes, I believe there is no error in your test. I also try your test immediately. But one test may be not enough.
Could you please spend some time on my test example and tell me what's wrong with it?
I think my test example uses the correct export and import methods provided with TeeChart.

After my example started, I click operation--> save.
Then click operation--> load, the saved tchart will not presented correctly.
I am confused with this problem for several months.

thanks again for your time and reply.

Hello,

In your sample code you are adding data at X 1 and 2:

Code: Select all

chart1.addSeries(new Bar());
chart1.getSeries(0).add(1, 10);
chart1.getSeries(0).add(2, 15);
chart1.getSeries(0).setTitle("A series");
..and you are adding the labels at 0 and 1. At 0 there is no data and so no label appears. There are other ways to paint labels at all locations if required.

Code: Select all

bottom.getLabels().getItems().add((double) 0, "MyXLabel-1");
bottom.getLabels().getItems().add((double) 1, "MyXLabel-2");
Alternatively there are different approaches to adding labels.

For example you could add them with the data:

Code: Select all

com.steema.teechart.styles.Bar bar = new com.steema.teechart.styles.Bar(chart1.getChart());

bar.clear();

bar.add(0, 123, "ABC", Color.RED);
bar.add(1, 456, "DEF", Color.BLUE);
bar.add(2, 321, "GHI", Color.GREEN);
bar.add(3, 321, "JKL", Color.YELLOW);
chart1.getSeries(0).setTitle("A series");
will give the following output:
JavaExport1.jpg
TeeChart Java template export 1
JavaExport1.jpg (136 KiB) Viewed 32046 times
or you can override the default labels as you have done (here applying the index to two of the points that have been added):

Code: Select all

com.steema.teechart.styles.Bar bar = new com.steema.teechart.styles.Bar(chart1.getChart());

bar.clear();

bar.add(0, 123, "ABC", Color.RED);
bar.add(1, 456, "DEF", Color.BLUE);
bar.add(2, 321, "GHI", Color.GREEN);
bar.add(3, 321, "JKL", Color.YELLOW);
chart1.getSeries(0).setTitle("A series");
    
chart1.getAxes().getBottom().getLabels().getItems().add((double) 0, "MyXLabel-1");
chart1.getAxes().getBottom().getLabels().getItems().add((double) 1, "MyXLabel-2");
That will give the following output:
JavaExport2.jpg
TeeChart Java template export 2
JavaExport2.jpg (132.88 KiB) Viewed 32041 times
I hope that may be of help.
