Height of data is not displayed correctly

Hi,

I have data sets where most values are very low with only a few but very high peaks (up to 10^10). Sometimes it happens that in the 3D display the peaks do not seem to be displayed according to their actual height but much lower. With the axes scaled according to the max value this is obvious. The red peaks in the attached screenshot should be several 1000 units high but they are displayed only as high as 10 to 15.

What do I have to change for them to be displayed correctly?

Regards,
