Patch for the Time Axis X grid values #151

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This patch changes the X axis on the Time chart to be easier to read/use, by 
aligning the grid with "normalised" values (day, 12 hours, 6 hours etc).

I've added some screenshots to demonstrate the change.
In this case, I've also changed the date format, depending on the zoom levels, 
but even if it used the standard format - it's still much much more useful, 
than creating the grid by splitting the "long" date range mathematically :)

The patch itself is non-breaking (it will use the current implementation by 
default). I guess a new method in the ChartFactory class would be useful to 
enable this functionality (unless of course you want to make it work like this 
by default, which I think would be a great idea) :)

Please check this bug again, I see it in current achartengine-1.0.0.jar .

See attach image.

Inputed data:

 List<Date[]> dates = new ArrayList<Date[]>();
 List<double[]> values = new ArrayList<double[]>();
 int length = titles.length;
 for (int i = 0; i < length; i++) {
      dates.add(new Date[12]);
      dates.get(i)[0] = new Date(108, 9, 1,22,35,36);
      dates.get(i)[1] = new Date(108, 9, 1,22,35,37);
      dates.get(i)[2] = new Date(108, 9, 1,22,35,38);
      dates.get(i)[3] = new Date(108, 9, 1,22,35,39);
      dates.get(i)[4] = new Date(108, 9, 1,22,35,40);
      dates.get(i)[5] = new Date(108, 9, 1,22,35,41);
      dates.get(i)[6] = new Date(108, 9, 1,22,35,42);
      dates.get(i)[7] = new Date(108, 9, 1,22,35,43);
      dates.get(i)[8] = new Date(108, 9, 1,22,35,44);
      dates.get(i)[9] = new Date(108, 9, 1,22,35,45);
      dates.get(i)[10] = new Date(108, 9, 1,22,35,46);
      dates.get(i)[11] = new Date(108, 9, 1,22,35,47);
    }
 values.add(new double[] { 142, 123, 142, 152, 149, 122, 110, 120, 125, 155, 146, 150 });

How Can i integret it to the achartengine.jar ?

#5 you can't integrate it in the jar file. You have to download the source code 
of AChartLibrary, apply the patch and recompile it.

Also, as dandrome...@gmail.com mentioned in #3 - it's already been applied in 
the source code. So no need to do anything, just take the latest source and 
compile it.

You can download the nightly builds here: 
https://repository-achartengine.forge.cloudbees.com/snapshot/org/achartengine/ac
hartengine/1.1.0/

No need to rebuild it from source yourselves.
