Camparing individual values in a bar chart

Hey,

I need help.

I want to compare individual values (e.g. maximum of a channel) with each other in a bar chart. The whole thing should then run automatically with a Python script. Anybody got an idea? I can only display a signal through time or other channels at any time. In the X-axis should simply read measurement 1,2,3,..., and in the y-axis the respective maximum value of a channel.

Thanks for your help!
