Hi,

Request your suggestions on how to remove/format the -5 (negative five) gridline from the total 7 gridlines. I still need the number -5 in the axis
Thanks in advance for your time and response.

Test to Format Plot Area's Border line to Solid and color to white.
Ps. same time the most right gridline could be 'white' too.
