bug whit TWindRoseSeries

[cfalcot]

Hello,

I would like to submit a bug whit TWindRoseSeries. If I try to draw:

Code: Select all

Series1.addXY(270, 10);

I have a point in front of E and not in front of W... so I must draw:

Code: Select all

Series1.addXY(360-270, 10);

to be right.

Best Regard's

Hello Cyril,

Yes, you are right.

However, it wouldn't be much important as TWindRoseSeries' finality is to draw winds.

As TWindRoseSeries is derivated from TPolarSeries it uses angle values. Considering a customer request we added the functionality to draw the polar labels clockwise or anticlockwise so we may also should have considered populating the series according to this behaviour.

I've added your suggestion to our wish-list to be considered for future releases. Meanwhile, you will have to use the workaround you already found.

Hello,

I have the same problem with Wind / Polar charts. It is very important for me, as I do scientific visualizations.

However, it wouldn't be much important as TWindRoseSeries' finality is to draw winds

.

Not quite right. A windrose by international standard has to work clockwise.
The standard is N = 0° = Top, E = 90° = right. Any compass works like that.

I've added your suggestion to our wish-list to be considered for future releases. Meanwhile, you will have to use the workaround you already found.

I'd like to urge you strongly to add this feature. The windrose is great, but not very usable because of this bug (no marks, no DBcharts, ...).

Polar charts as realized now are not very useful as scientific tools.

Best regards,
Max.
