Bar Graph Min and Max

Greetings friends,

I have run into a bit of a halt in one of my programms and I am trying to figure out a solution to my problem, if there even is one.

So, I have an application where a liquid is to be cooled and then heated to certain setpoints, configurable through the display. This procedure repeats (cooling --> heating --> cooling --> heating etc.) until the system is shut down. I have this all figured out.

Now, my problem occured when I added a bar graph to represent this change in temperature in the liquid on the display. I can see that you can set the minimum and maximum values of the bar manually but I would like my MIN and MAX values to be the setpoints of the cooling and heating procedure, therefore configurable whenever I change the values of the setpoints on the display.

Is this even possible? I have been toying with this for some time but I am stuck, to be honest :(

Any ideas will be highly appreciated! I am working on a LOGO 8 Standard and Soft Comfort v8.2.1

Oh man, now I am sad, it would have been a cool visualisation!

Anyway, thank you for the answer!

If you need a solution for your problem, then see the example in attachment. The bargraph will start and end with adjustable parameters. Sometimes it's better to have a look from the other side. 

Scaling the bargraph is fixed by parameter, when you create the program. Therefore use a fixed bargraph from e.g. 0 to 1000 and normalize the display value to the same area.
