Black area on Property Checkpoint Picture from test log

Hi,

Can somebody help me how to remove/prevent this black area on my property checkpoint. I would like to get the picture of the whole report.

It is a report that goes all the way to the bottom of the page, it only shows a portion of it and it is also the one that is shown on the page. Can the checkpoint get the whole report from start up to the bottom of the screen?

 
(the actual display of the page on the screen when i run the report, need to black out items that are company confidential)

Figure 1 The checkpoint is for the bar graph below. 

Figure 2: Picture from the property checkpoint that shows that it only displaying the portion that was displayed on the page, it doesn't scroll at the bottom.

Thanks!
