SMath is similar to Mathcad but not the same.
If you give SMath a try you will get used to it.
I find documentation is quite detailed actually.
Not a problem if you don't, feel free to ask anything.
This is a very friendly forum, you will get a working answer.

You can either use a new plot for dots or feature of X-Y plot plugin.
Double click to X-Y plot, there is option for dots under;
Traces > Appearance > SymbolStyle > Type.
I generally prefer using 2D plot for its simplicity whenever I can.
Sometimes X-Y plot plugin is required nonetheless, especially on x + y functions.
X-Y plot can do anything 2D plot does, except the animations.
And X-Y plot plugin has many detailed customizable options.
You have much control over Axis, Title, Labels, etc.
Here is a sample for your request.

He has knowledge no doubt, but no intention to help people.
You will only see him promoting himself and his samples.
His replies won't be related with your requests.
And he has seriously flawed engineering sheets.
Worse of it, he will insist on his mistakes.
Don't take anything he writes as true, correct or relevant.
