When *$matches[1]* is *$matches[1]* or *$matches[1]*, *$matches[1]* is taken as an exact value. When *$matches[1]* is *$matches[1]*, *$matches[1]* is a minimum value and Graph might add more if it thinks it will improve the graph.

I entered "1" by Steps at the argument range. That could not work. But can you give me a quick explain about that function, please?]]>

first of all, thanks that I have found such great app!

But, I have a problem:

I am trying to plot a simple linear function like f(x)=10-0.5x e.g. I know I could plot a line between two points to reach the goal, but this is not the proper way to do.

So I insert the function into the program and ... see nothing. If I enable the hatching under the function, I see the area under the function, but I can not see the function line.

I am sure it is just a failure by mine, but could not find it yet.

Someone any suggestions?

Thanks in advance!
