Cannot update plot trace options

[MW_Tango]

Although I can create a plot, I am not able to format it. The Symbol, Line Style, Color Scheme, Trace Thickness, and Surface Fill options are all grayed out. Only can change Trace Color.

Update... I can change all plot parameters for a trace when first creating a new trace, but the changes do not stick. Seems to default back to original styles. All styles except Trace Color are grayed out after it's created as before. I'm working with the trial version. That an issue?

Note - status bar says "Full Functionality - 15 days remaining" for the trial.

 Hi,

Please specify which version of the program you are using and the version of Windows OS?

Hi,

Thanks for the reply.

The 'About' page says I'm using 'PTC MathCAD Express Prime 8.0.0.0' (see below).

For OS, I'm using 'Microsoft Windows 10 Home' (Version 10.0.19043 Build 19043).

@VladimirN 

I found out what I did wrong. My x-axis variable was way too large. My bad!

This failed...

This worked...  (kudos to @LucMeekes from another posting)

FYI, for reference, here's the plot I was trying to make...

Working with 'Chart Components' now. That's a whole new thing to learn. So far have this...
