Creating cwgarph annotations with long arrays

[Ohad]

I'm trying to display CWShape annotaions using long coordinate arrays (more then 520 coordinates). When I do so, no shape is displayed. The problem can be seen with many shape types (polygon,region,line...). Apperantly there is a limit to the size of the Xcoordinate,Ycoordinate arrays.
Is that true?
any workaround?

Hello

Could you attach a small project that demonstrates this problem? Perhaps I could test this out on my end. I assume you are using the CNi wrappers instead of the classwizard generated wrappers, the CNi objects are alot more easier to use.

Thanks

I'm using component works starter kit (vb) and add the controls to the vc++ project.

I attached the polygon creation function.

Hi,

I created a small VB project showing this problem.

Press the create plot key and then move the cursors

Thank you

Hello

Apparently it doesnt like a polygon shape with more than 500 coordinates, anything greater than 499 and nothing gets displayed on the graph. I have filed a corrective action request on this, but I cannot tell at this time when this might get fixed.
For now, the only way around this is to not use a polygon of greater than 499 points

Sorry for any inconvenience this is causing you. If you send in an email from ni.com/ask, if there are any updates, I can better inform you, but I cannot guarantee an immediate solution.

FYI,

The problem is not only with polygons, it occures with Lines and regions as well (I haven't checked other types).
