Wrong axes layout in 2D about jzy3d-api HOT 9 CLOSED

Use Chart2d with Chart2dComponentFactory.

Dear jzy3D team,

I have observed the following issue: when the view is in "2D mode" (both
using ViewPositionMode.FREE or ViewPositionMode.TOP), axes layout is wrong
since labels are overlapped within axes and chart. You can see this effect
in the following image:

However, as you can see in the following two images, when the view is in
"3D mode" (even when it is very close to the "2D/Top" view), labels are
correctly displayed without being overlapped.

Is there any way to fix it? Can you consider fixing this issue in jzy3d?

Thank you very much for your support.

Regards.

Dear Martin,

thank you very much. I have tried it and it looks much better using Chart2d with Chart2dComponentFactory.


It would look perfect if the X axis tick lines were not overlapping X axis labels, but it looks much better now.

Thank you very much for your support.

Dear Martin,

I have detected an issue with Chart2d: it does not respect the image proportions even when setSquared(false) is used.

Here is the result obtained using AWTChartComponentFactory and Chart:

And here is the wrong result obtained using Chart2dComponentFactory and Chart2d:

In both cases I invoke chart.getView().setSquared(false) after creating the chart.

Is there a way to fix this issue?

Thank you very much.

I have just seen that class View2d (the one used by Chart2d) overrides computeSceneScaling() so that it always return squarify(). I think that this must be the reason why setSquared(false) does not have effect on Chart2d.

Do you know any way of having a squared Chart2d?

Thank you very much.

I confirm it is a non desired behavior.
You might try removing the override, or override the override with
overriden impl or wait for a fix but I can t promise any deadline

Thank you very much for your suggestion. Indeed, removing the override is precisely what I tried. This way, the setSquared(false) works and the image is rendered respecting its real dimensions. Finally, to obtain a slightly better layout of the axes I have overriden the drawAxisTicks and layoutHorizontal in AxeBox2d class.

It would be nice if you can fix this in future versions.

Best regards,

Hugo.

Could you kindly perform a pull request so that your improvements will be
merge in future version?

Thank you!

I think that our solution is a path that works for our application but further investigation is needed in order to introduce the changes in the official releases. I will investigate a better way to fix this issues and if I found it, I will perform the pull request.

Thank you for your support too.

Version 2.1.0 now provides much better 2D charts! See the tutorial chart2d package.
