[jCharts-users] Swing app question

[<fra...@ag...>]

Hi,

I have only downloaded jCharts today, so my experience with package is not great. I really want
to use the package to embed charting components in Swing applications. Within the distribution
I found an example of a Swing PieChart. I tried to follow that example to try and reconstruct
my own Swing bar chart based on the distributions bar chart example.

The code is given below. All seems to work, the frame gets drawn but finally I get an exception
when the "axisChart.render()" method is called:

$ source runharness
/cygdrive/d/mpowerdem/src/wdiscovery
java.lang.NullPointerException
        at org.jCharts.Chart.render(Unknown Source)
        at com.agilent.wdiscovery.MainFrame.initComponents(MainFrame.java:81)
        at com.agilent.wdiscovery.MainFrame.<init>(MainFrame.java:34)
        at com.agilent.wdiscovery.LaunchWirelessApp.<init>(LaunchWirelessApp.jav
a:20)
        at com.agilent.wdiscovery.LaunchWirelessApp.main(LaunchWirelessApp.java:
49)

I have tried other things in despair but I'm not getting very far. Can anyone help or point
me to some other Swing based examples?

Thanks,

Francisco

[jCharts-users] 0.7.1 is out

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

Fixes:

* Horizontal Plots not starting the ticks at the y-axis, were offset. This was because some code
for the next release accidently was inserted into the code base.  
* Code accidentally added which caused the above bug, has: Area, Line, and, Point, charts plot
start along the y-axis rather than offset, so those plots fill the entire plot area.

there is a bug in the release. We will do another release to fix this today. Sorry about that.

[jCharts-users] Re: [jCharts] Pb displaying x AXIS.

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

it appears there is some code in the 0.7.0 source which is for the next release, namely code which
starts the plot for Area, line, etc..., that starts the plot at the y axis rather than offsetting
it.

if you need a quick fix:

take a look at the: deriveAxisValues() method in AxisChart.java

/******************************************************************************************
*
*****************************************************************************************/
protected void deriveAxisValues()
{
this.xAxis.computeLabelFilter();
this.xAxis.computeShouldTickStartAtYAxis( this.iAxisDataSeries,
this.axisProperties.getXAxisProperties() );


make it so the call to: this.xAxis.computeShouldTickStartAtYAxis(...) so it is the second line in
the method as above.

Re: [jCharts-users] Legend Icon

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

There is code in the beta 2 for doing this on Point Charts which you could easily modify for line
charts. Take a look at Legend.java on line: 235

We could do this for the next beta...

Hi,
I'm doing a line chart at the moment and i wonder
whether the icon shown on the legend can be the same
as the shape I have choosen for the graph.

For example if i choose
PointChartProperties.SHAPE_DIAMOND for a data, can the
icon beside the data name on the legend be a Diamond
instead of the default square shape?

[jCharts-users] Changing the minimum value for YAxis of AxisChart

[Bill B. <bil...@te...>]

Is there a way to change the minimum value for an AxisChart?  That is, =
instead of going from 0 to 1000, I want it to go from 500 to 1000.

Thanks,
Bill

RE: [jCharts-users] Re: [jCharts-developers] ChartType.LINE question

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

If i understand you correctly, you want:

|
|
|
X-----


where X is 0,0 on your chart and the '|' is y-axis and '-' is the x-axis?


right now you have:
|
|
|
----X-----


This is not possible.  I should have a moment to take a look at it tonight for inclusion in the
0.7.0 code.

RE: [jCharts-users] Re: [jCharts-developers] ChartType.LINE question

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

oh, i thought you were using the XY Scatter Plot in the 0.7 beta 2.

a line chart y-axis would start at 0 by default if there are no negative values.  The x-axis are
just String Objects.  If you are looking to plot x,y coordinates like the equation y=x^2, use the
XY Scatter Plot in 0.7.0.  

If you are trying to plot label,value, you can use a Line Chart from 0.6.0 or 0.7.0.  If you want
zero as the first label, pass "0" as the first item in your axis labels data.

[jCharts-users] Re: [jCharts-developers] ChartType.LINE question

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

I am not sure i understand.  If you want it to begin at the origin, include 0,0 as your first data
point.

Or are you saying you want the x axis zero value to be at the y-axis?

[jCharts-users] 0.7.0 alpha 2 is out!

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

New in Alpha 2

* Fixed bug in alpha 1: NullPointer when trying to render an AxisChart without a legend 
* Fixed bug in alpha 1: XAxis was rendering a grid line over the y-axis on a horizontal plot, so
axis was always gray. 
* Copied the SwingTest.java from the test code to the demo package and named it SwingDemo.java 
* Bar and Clustered Bar, both vertical and horiztonal, allow value labels to be placed on them.
Run the examples web app and look at the Bar Chart to see this. The source is in the demo package

[jCharts-users] jCharts 0.7.0 alpha 1 released!

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

The first alpha for jCharts 0.7.0 has been released!  Remember this is an alpha release, so things
are still being added and changed...but it provides an early glimpse of things to come.


*Added a Validation framework to assist developers in tracking down data problems. The Chart
Properties Object now contains a method setValidate( boolean ) which allows developers to toggle
the validations for speed. The IDataSeries interface has a new method: public void validate()
throws PropertyException  

* Removed all 'transient' data members and made everything Serializable. 

* The encode( Chart chart, HttpServletResponse httpServletResponse ) method has been renamed to
encodeServlet 

* A framework has been introduce which allows for custom scale increment code to be included in
Axis Charts. Simply extend the org.jCharts.axisCharts.scale.AutomaticScaleCalculator Class and
override the computeIncrement( int ) method.  

* Bug fix: x-axis labels will no longer go off the right edge of the chart image. 

* Horizontal Bar, Stacked Bar, and Clustered Bars have been added. 

* Scatter Plot Charts have been added. 

* Servlet demos have been updated to be easier for non-java programers to understand as many have
requested this. So inheritance has been avoided and the code is self contained so you can just
change values and use them as they are.

[jCharts-users] 0.7.0 status

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

got the servlet demos compiling again.  A couple of the chart servlets dont want to work though. 
And the stupid jsp wont work; there must be some whitespace in there somewhere. I would love to
rip the chart.jsp out of there as you really should not create and encode a chart in a jsp.

Added data set interface and  data implementations for Scatter Plots.  Not sure if the exact
interfaces will stick but will find out when integrate into the AxisChart render.

There could be an **early** alpha of 0.7.0 in a week or two... This would definitely include the
horizontal bar type charts, validation framework, refactored AxisProperties implementations with
the new LabelAxisProperties and DataAxisProperties Objects.

I think there will be some form of labeling code for axis charts integrated in the next week so
maybe that will be the cutoff for an alpha release.

Any feedback?
