I can't move the graph up and down

[Calvete]

Can anyone help me, I have a problem with the Platform. I can't move it vertically. I can only move it horizontally.
At certain times the graph disappears below or above due to this problem. I've tried everything and the problem continues.

Hello Calvette,

You can vertically move the chart by holding the Ctrl key on your keyboard and then click and hold the left mouse button on the right side of the price axis and move up or down.

Damn, I didn't know that.

Thank you so much.
