sorry, for some reason i was thinking you could only do this on the line charts.  I guess I have
been out of this for a little too long.

[Nathaniel G. A. <nat...@ya...>]

i think what he is after is having a single bar extend above and below the zero line.  But, yes,
if it is two bars, he should be able to do it with your code.

RE: [jCharts-users] Above and below bars

[Chris M. <ch...@de...>]

Nathanial, you can do this in the current CVS code with a stacked bar chart
with negative values in one data set and positive in the other. I posted a
sample graph last week.

Re: [jCharts-users] Above and below bars

[Nathaniel G. A. <nat...@ya...>]

no this is not possible in the current code base.  I do not think it would be all that hard to
implement though.

ok. I will see if i can get some place holders up there and take a look too.  My work load is
finally slowing down a bit again and i might have some spare time.

[jCharts-users] Above and below bars

[Travis R. <tr...@gm...>]

Is it possible to make a graph with a positive value above zero and
negatives value below zero in same bar, like a net worth / income
expense graph like you see in Quicken?

RE: [jCharts-users] Multiple Y ranges

[Chris M. <ch...@de...>]

OK - all changes for independent Dual Y axis checked into CVS. Now you can
plot one set of lines on the left axis and another set against the right.
Look at the program in the test directory (DualAxisComboTestDriver) for all
the methods.

Nathanial - we need an area in the doco to put all this stuff ...

Having made all these comments I see that I haven't checked in my final dual
Y axis changes to cvs ... I'll do that in the next day or so (hopefully
today depending on work commitments). There will be an update to the
test/DualAxisComboTestDriver.java sample program

RE: [jCharts-users] Multiple Y ranges

[Chris M. <ch...@de...>]

Well that's your decision to make. We are using a CVS snapshot from the 1.0
branch (just post the Alpha release) for our production use. We did some
fairly intensive testing and QA but only in the areas of jCharts that we are
using (3D stacked bar charts, dual Y-axis and combo charts) and only with
the sorts of data that we can ever expect.

I'm not sure how widely used the 1.0 version is. Certainly the 0.74 release
is in use in a number of organizations.

In our organization we are all pretty heavy-duty Java programmers so we
don't mind fixing or tweaking the jCharts code if problems arise. And the
code is very nicely written as well so it isn't hard for us.

I believe the phrase is Your Mileage May Vary ...

So alpha is the one to use now?

RE: [jCharts-users] Gradient on each bar rather than across entire graph

[Chris M. <ch...@de...>]

Yes, as you can see from the sample code the dataset index is passed in.
Then if you want to count what bar you are up to then you just have a member
var to do that, the class is called on every bar draw. I've done this when I
wanted the bar colour to change when I reached a 'future' date.

Re: [jCharts-users] Gradient on each bar rather than across entire graph

[Nathaniel G. A. <nat...@ya...>]

why set the Paint n times, when you can set it once?  The thought at the time was there would be a
single Paint per dataset

you could just have a member which counts?  I think the index is passed in too.

[jCharts-users] Multiple Y ranges

[Travis R. <tra...@ec...>]

Is it possible to have a chart that has multiple Y value ranges, say one 
bar is measured on value 1-1000 and you want to
a second bar to be charted with the range 0-100 or something?  So if 
data set A was 900 the bar would be the same height as data set B at 90.

Re: [jCharts-users] Gradient on each bar rather than across entire graph

[Travis R. <tr...@gm...>]

I don't think this will work very well for me since the paints are set
dynamically while creating the graph, so how would I get at which
paint is for which bar from the preRender method?  I would need a
axisValueRenderEvent.getPaint() or something.

Why doesn't jcharts just set the paint for each bar it draws?  Or
another way of putting that is why does it have the current behaviour?

RE: [jCharts-users] stackedbar with value < 0

[Chris M. <ch...@de...>]

Actually it works fine on the 1.0 branch - that's something I put in. Just
set values to negative.

Attached chart from the StackedBarTestDriver with these values:

		double[][] data = {{-280, 16, -150, 90, 60, 200, 150, 60 },
{80, 216, -10, 30, 15, 90, 150, 87 } };

[jCharts-users] Bar Chart Value Labels Masked

[Rod M. <rma...@ve...>]

Most of the time bar chart value labels are correct:

____________________________

   foo
|------|
|      |    bar
|      | |------|=20
|      | |      |=20

Sometimes bar chart value lables near the top of the range (default
scale used) are squished:

_______________________________

|--foo--|
|       |
|       |    bar
|       | |------|=20
|       | |      |     =20

Sometimes pushed right in to the bar. Depending on color, not a good
thing.=20

|-------|
|       |            baz
|  foo  |          |-----|
|       |   bar    |     |
|       | |------| |     |
|       | |      | |     |

RE: [jCharts-users] Overhead Transparencies in Bar Charts

[Rod M. <rma...@ve...>]

Since showing only one bar chart is normal behavior I will use the =
clustered bar chart for comparison and investigate the area charts as =
you suggest.  I have a requirement that all of the data must be visible: =
clustered bars works and so will overlayed series with translucent =
paint.=20

	this is not possible.  Only one dataset will get plotted on a bar =
