Build the element yourself using the readily provided primitives (99.9 percent of the time this will suffice!)
There is a readymade bargraph element, but you can design your own bargraph (tip: use a rectangle or so).
When designing it yourself you will learn new cool stuff about the visualisation as a bonus.
I'm already doing that, but was wondering if there were some free open add-on somewhere or a description how to build your own eg if they are save in a xml style or so.
Since I work with Festo and they do have a HMI libray where you use studio designer where you have a lot of ready very nice symbols available, (whic for sure only work with Festo HMI scereens) and thereby are "Paid" it makes sense.
It might be the same if you could add in a library with symbols for web visu on certain models of PLC
Yeah I know Google.... but I really did not find what I had in mind
obtain the "visu-toolkit" which is a professional CODESYS add-on which you have to pay for.
As far as I know it comes with a mandatory training at CODESYS or on site.
For further details on it you should contact sales (or search this forum as there are some topics on it)
That might be a route, need to loo into symbols and pricing
