I need to replace all of the graphs we were using on our HMIs with similar graphs from chart FX... I have done all of them except for one. An image of what we have now is attached. Basically, I have different objects of different size and shape. I want to show their height on this graph. To do so, I need to be able to control the size / shape of different plugs & place them close together. I'm a bit new to all of this, so all advice is welcome.
