non-GMT DateTimes offset

Post by Saman » Wed May 21, 2014 9:18 am

Hi,

When you use DateTime as chart X axis, the graph is not align properly. It always shifts to right.

Can you please check and let me know how to get this right.

this is the code i used

Code: Select all

@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		
		
		LinearLayout group = (LinearLayout) findViewById(R.id.teeChart);
		chart = new TChart(this);
		group.addView(chart);
		
		
		chart.getPanel().setBorderRound(7);
		chart.getAspect().setView3D(false);
		
		
		//common graph settings
		chart.getLegend().setAlignment(LegendAlignment.BOTTOM);
		chart.getLegend().setLegendStyle(LegendStyle.SERIES);
		chart.getLegend().getFont().setSize(20);
		
		chart.getHeader().getFont().setSize(25);
		
		chart.getAxes().getLeft().getTitle().getFont().setSize(15);
		
		chart.getAxes().getLeft().getLabels().getFont().setSize(15);
		
		chart.getAxes().getBottom().getLabels().getFont().setSize(15);
		
		ThemesList.applyTheme(chart.getChart(), 1);
		
		try 
		{
			series = Series.createNewSeries(chart.getChart(), Line.class, null);

			series.getXValues().setDateTime(true);
			
			series.add(new DateTime(2014, 05, 16), 5);
			series.add(new DateTime(2014, 05, 17), 8);
			series.add(new DateTime(2014, 05, 18), 3);
			series.add(new DateTime(2014, 05, 19), 4);
			series.add(new DateTime(2014, 05, 20), 0);
			
			
			series.getMarks().setArrowLength(0);
			series.getMarks().getFont().setSize(15);
			
			chart.getAxes().getBottom().getLabels().setDateTimeFormat("dd MMM");
			
			chart.getAxes().getBottom().setIncrement(Utils.getDateTimeStep(DateTimeStep.ONEDAY));
			
		}
		catch (Exception e) 
		{
			e.printStackTrace();
		}
	}
Thanks
Saman

Hello Saman,

This sounds similar to this:
http://bugs.teechart.net/show_bug.cgi?id=420

Could you please show us how do you set your layout?
If you are sharing the LinearLayout for texts and the chart, can you please try using an independent LinearLayout without margins for the Chart?

Hi Yeray,

Following is the code I use.
I changed the layout to only have chart as follows, but still the issue is there.

Layout activity_main.xml

Code: Select all

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".Main" >

    <LinearLayout
        android:id="@+id/teeChart"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">
    </LinearLayout>
    
</RelativeLayout>
Activity class Main.java

Code: Select all

public class Main extends Activity {

	private TChart chart;
	private Series series;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		
		
		LinearLayout group = (LinearLayout) findViewById(R.id.teeChart);
		chart = new TChart(this);
		group.addView(chart);
		
		
		chart.getPanel().setBorderRound(7);
		chart.getAspect().setView3D(false);
		
		
		//common graph settings
		chart.getLegend().setAlignment(LegendAlignment.BOTTOM);
		chart.getLegend().setLegendStyle(LegendStyle.SERIES);
		chart.getLegend().getFont().setSize(20);
		
		chart.getHeader().getFont().setSize(25);
		
		chart.getAxes().getLeft().getTitle().getFont().setSize(15);
		
		chart.getAxes().getLeft().getLabels().getFont().setSize(15);
		
		chart.getAxes().getBottom().getLabels().getFont().setSize(15);
		
		ThemesList.applyTheme(chart.getChart(), 1);
		
		try 
		{
			series = Series.createNewSeries(chart.getChart(), Line.class, null);

			series.getXValues().setDateTime(true);
			
			series.add(new DateTime(2014, 05, 16), 5);
			series.add(new DateTime(2014, 05, 17), 8);
			series.add(new DateTime(2014, 05, 18), 3);
			series.add(new DateTime(2014, 05, 19), 4);
			series.add(new DateTime(2014, 05, 20), 0);
			
			
			series.getMarks().setArrowLength(0);
			series.getMarks().getFont().setSize(15);
			
			chart.getAxes().getBottom().getLabels().setDateTimeFormat("dd MMM");
			
			chart.getAxes().getBottom().setIncrement(Utils.getDateTimeStep(DateTimeStep.ONEDAY));
			
		}
		catch (Exception e) 
		{
			e.printStackTrace();
		}
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}
Hope this will help you to check the issue.

Thanks
Saman

Hi Yeray

I found the isuue. Your DateTime only works for GMT time zone. so from the code we have to change the default time zone to GMT

following code worked.

Code: Select all

DateTime dt = new DateTime(2014, 05, 16); 
dt.setTimeZone(TimeZone.getTimeZone("GMT"));
series.add(dt, 5);
dt = new DateTime(2014, 05, 17); 
dt.setTimeZone(TimeZone.getTimeZone("GMT"));
series.add(dt, 8);
dt = new DateTime(2014, 05, 18); 
dt.setTimeZone(TimeZone.getTimeZone("GMT"));
series.add(dt, 3);
dt = new DateTime(2014, 05, 19); 
dt.setTimeZone(TimeZone.getTimeZone("GMT"));
series.add(dt, 4);
dt = new DateTime(2014, 05, 20); 
dt.setTimeZone(TimeZone.getTimeZone("GMT"));
series.add(dt, 0);
Thanks for your support.
