User Defined Tick Marks

Gunjan Nigam — Mon, 07 Mar 2011 12:50:13 -0000

There should be a method to create Tick Marks at uniform Intervals. Currently the tick marks are generated according to the data in Trace. It should be overridden a method which can generate uniform Tick intervals like 10,20,30 etc... This way Number of Grid Lines on any Axis can also be controlled by the user

Chart 2D features

omkar — Fri, 04 May 2007 06:03:44 -0000

Hi,

I have to use a java based chart in my project. But, i don't know the features provided by Chart2D and whether it will fit into my project.

The technologies i use in my project are :-
jdk1.4.1
Struts 1.2.8
JSP
Tomcat
iBatis ..etc.,

I want to generate chart depending upon certain Business related parameters that the end user will select from the form and submit, then corresponding data will be retirved from the database and used to plot a chart as an image which the user must be able to save as JPEG. Also, does CHART2D provide facility to tweak the parameters of the chart ...for e.g., FONT, LEGEND, COLOR, LINE SHAPE and COLOR, TICK MARKS ON THE AXIS...etc.,

I would be very greatful if you can tell me if such things are supported by Chart2D

Million thanks in advance

Thanks and regards

add method to writ e to Graphics2D object

s booth — Wed, 24 Aug 2005 10:22:39 -0000

Chart2D only provides a getImage call to retrieve a
RenderedImage object
We want to be able to create SVG files using the apache
batik
classes.
If chart2D had a method that reders the graph in an
externaly provided Graphics2D object directly rather
than using its backing image then this would be easy.
At the moment we need to modify the chart2D source to
add this functionality
It should not be too hard as the code already accesses
the image object as a Graphics2D.

Does Chart2D support with Mouse Behavior features?

Hi,

May i know Does the Chart2D support the functions
with mouse behavior?

I learn that we have to implements mouse motion
listener and mouse listener... however thought i have
implemented it, it still doesnt work properly.

Like said i want to get the X and Y coordinates from the
chart. the X Y coordinates does not show in the chart
after a mouse click. However, i tried to make a simple
testing by print out the coordinates in the console
window and it does work.....

Can anyone please teach me how to show out the X Y
Coordinate after a mouse click in the chart? thanks if
someone can help me. thanks

B/W for printing

To print the grahic with java print method shows poor
resutls for black and white printers. I tried to use
only grey-shades. But some texts are not possible to
set. But light_grey is not printing very well.

sorting of bars in clustered bar chart

Brendan McMahan — Mon, 22 Mar 2004 20:57:52 -0000

Hi, I'd like to be able to sort the bars in each
cluster based on the value (length of the bar), rather
than always displaying the bars in the same order. Is
this possible? If not, I might add the feature myself,
but if someone could give me some pointers into the
code to get started that would be great. Thanks,
Brendan McMahan

Code Cleanup and getting rid of final classes

Mike Hostetler — Thu, 23 Oct 2003 18:05:44 -0000

When you import the source into Eclispse, all sorts of
bells go off due to unused imports and using static
methods incorrectly. Also, the chart classes are all
marked "final" without any reason, and I had reason to
subclass them.

The attached patch cleans up the code to be useful
inside Eclipse and unmarks the classes as final. It is
functionally the same.

How to use thousand separator for the numbers axis?

Jose Marcelo Silva Fascio — Mon, 14 Apr 2003 19:55:23 -0000

Is there a way to have thousand pontuated numbers
on the number axis?

I work with very large numbers and it's difficult to see
their magnitude without the pontuation.

Thanks.

Avoid a line chart to plot a NaN value.

Jose Marcelo Silva Fascio — Thu, 10 Apr 2003 16:21:28 -0000

Hi,

I'm using Chart2D and think it is a very good library.
Congratulations Jason.
Using Chart2D to plot a line chart, I'm having
problems with Float.NaN values. When I use them,
they are considered zero values, and the line to that
point is ploted. What I need is that, if a value is
Float.NaN, the line stops on the previous value, and
starts again after the next value.

Is this possible to do with the current version?

Thank you very much.

J.Marcelo.
