problem with radar

[rubby]

Hello,

I create a radar in TChart and put it on a JPanel,
When i change the size of panel,
the radar will change the size of itself. However,in a wrong way.

When I compare the radar with the radar generated by excel,
this confirm my judge.

Could you please tell me how to address this problem?
Thanks.

Hi,

Could you please post some screenshots of the problem and a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

My code is as follows.
In the attachment, you can find two png files.
In the first png (radar1.png), you will see the radar graph is wrong.
In the second png(radar2.png), you will find that the value "33" is not showed correctly either.

Thus, when user changes the size of the dialog, the radar graph changes in a wrong mode.

Hi,

In the first png (radar1.png), you will see the radar graph is wrong.
In the second png(radar2.png), you will find that the value "33" is not showed correctly either.

This code:

Code: Select all

Radar series1 = new Radar(tChart1.getChart());
series1.add(50);
series1.add(33);
series1.add(56);
series1.add(88);
series1.add(108);

tChart1.getAspect().setView3D(false);

Gives me this:

That looks as your radar1.png image. However, I'm not sure to find any alternative in your code to generate the radar2.png.
Also, in radar2.png I think the value "33" is drawn correctly. Note it's the lower value in the series, so the axis minimum starts on it by default, so it's drawn on the center.

Then, adding this:

Code: Select all

series1.setCircled(true);

I think will give you the expected result for radar1.png.

And adding this:

Code: Select all

series1.getVertAxis().setAutomaticMinimum(false);
series1.getVertAxis().setMinimum(0);

I think will draw the "33" where you'd expect.

Thanks Yeray , my problem is addressed.

Hello,

I still find that radar graph of teechart is different from the excel radar.
one is anticlockwise, the other is clockwise .
I do not find any method to set the radar graph of teechat to clockwise.

Does it exist?
thank you.

Hi rubby,

There's setClockWiseLabels for that. It should reverse the painting order of series and labels but it's not working so I have added it [ID450] to the bug list to be fixed.

Hello，

I encounter a strange problem with radar graph.

the axis is not in the right position.【radar axis wrong position.png】
what i need it the one in the attachment 【radar correct position.png】.

How can i set the current position of this axis by myself.
is it radar.getVertAxis()... or something else?
Thanks.

Hi rubby,

I can not reproduce this. Are those screen-shots made with different TeeChart versions? Otherwise, which settings differ from one chart to the other?

Thanks in advance.

[rubby]

Hello,
I am sorry for late reply because of something.
This always happens when i saved the radar graph as xml files and import it again (in my software which integrates Teechart).
However, i can not reproduce this problem by a simple example.

this screen-shots use the same and latest version.


Thanks.

Hi,

I've made a test and the following seems to work fine for me here.

Hello,

thanks for the reply.
I also code some simple examples, but the problem can not happen either.
I would let you know if i get the idea of how to reproduce this problem.

Thanks.
