Adjusting view of "Set ease for multiple parameters "

Hi. I have this icon: (attachment 1).
After click on it the view of 2 keyframes is stretched beyond comfortable view (attachment 2).
The space between these keyframes is 4 frames (not so little as it looks).
Are there some hidden secret hotkeys to let me stretch the view horizontally? Probably not, but i thought i’ll try to post it here. Thank you.
