My problem is that the axisLabels (the label that goes at the very end of the axis) are not correctly truncating when given a large String value. For example, an axisLabel set to a 200character string will simply extend out forever, overflowing both the RadarChart container and any of its parent components. Normally Flex Label components will truncate and tooltip in these scenarios but I think your use of Util.actualize() is negating this base functionality. Any tips to help me along?

Also- I would like to remove the fill created for each series plotted, I just want the dots and the lines connecting them, but not the area fill that is created within the outlined portion of the RadarChart- any tips on how to accomplish that?

If I can get all this figured out I’ll push the changes to GitHub for possible inclusion in the main project, hoping that someone reads this as the last comment on this thread was quite a while ago!

I need to remove the swc dependency, I can see that you use:
ArrayExtension.extend()
Util.generateDefaultCSS()
Util.actualize()

Can you explain what these do so that I can replace this with code? Thanks!

I’ve already included the libraries and have copied the code into a .mxml file but there seems to be errors!

RadarChart {
colors: #FF0000, #00FF00, #0000FF, #41C04F, #296997, #26B69B, #CF5F0B, #A041C1;
axisColor: #FF0000;
backgroundColor: #00FF00;
}

radarChart.addAxis(‘A’);
radarChart.addAxis(‘B’);
radarChart.addAxis(‘C’);
radarChart.addAxis(‘D’);
radarChart.addAxis(‘E’);
radarChart.addAxis(‘F’);
radarChart.addAxis(‘G’);
radarChart.addAxis(‘H’);

radarChart.addSeries(’1′,{
A: 8,
B: 1,
C: 2,
D: 3,
E: 4,
F: 8,
G: 6,
H: 7
}
);

radarChart.addSeries(’2′,{
A: 1,
B: 2,
C: 3,
D: 4,
E: 5.5,
F: 6,
G: 7,
H: 8
}
);
radarChart.addSeries(’3′,{
A: 10,
B: 10,
C: 10,
D: 10,
E: 10,
F: 10,
G: 10,
H: 10
}
);

By default only 8 colours are available, so if you are adding more than 8 series you may get an error.

You may also get an error if you have supplied a different set of colours.

This solution would be to add a style tag to your applications main mxml file, making sure you specify enough colours for your series:

RadarChart {
colors: #257BB6, #B7247C, #CCC012, #41C04F, #296997, #26B69B, #CF5F0B, #A041C1;
}

Yes, I have tested this chart in flex4, but error occurred.

I think when flex 4 sdk complile and running the app, the problem occur.

error message looks like

TypeError: Error #1009: null …
at boost.charts::RadarChart/drawSerie()[C:\AES_FRAMEWORK\workspace\Test01\src\boost\charts\RadarChart.as:648]

How can I solution this problem?

I haven’t tested the chart in Flex 4, only Flex 3. What version are you using?

I’ve tried with this example in a flex project importing to the project this project (http://github.com/boost/radar-chart):

and into my application it show a dark rectangle, nothing more.

I don’t know which is the problem. Maybe Flex’s version…

Thanks in advance!

There is no way to achieve turning off the labels using the swc file. However, it wouldn’t be difficult to implement if you download the original source code from http://github.com/boost/radar-chart and modify it to switch off the labels (see function updateAxis on line 330 of RadarChart.as).

If you wanted to contribute this change back to the project the easiest way would be to create a free github account and fork the project.

i used radar_chart-1.2.swc. to create spider chart with 8 sides..

i dont want to display series points on the line like 0 1 2 3 4 ….

i want clean line apart from that i need to create a fencing for my spiderchat

How can i acive that functionality…

Please let me know
