Why isn't the x-Axis at the origin y=0?

Can someone tell me why this is happening and how to fix it?
(See the Mathematica code and output below.)

Perhaps because your first plot used {t,2,4}

You can probably change that if you include AxesOrigin->{0,0} in one or all the plots if that is what you really want.

Welcome to Wolfram Community! Please make sure you know the rules: https://wolfr.am/READ-1ST

The rules explain how to format your code properly. Posting code Images doesn’t help other members to copy your code. Please next time, make sure code blocks start on a new paragraph and look framed and colored like this.

int = Integrate[1/(x^3 - 1), x];
Map[Framed, int, Infinity]

You can also embed notebook or attach notebook.

If I understand the syntax for ParametricPlot, the first plot draws the line segment from the point (0,2) to the point (0,4). That’s the y-axis between y=2 and y=4.

Thanks for the AxesOrigin hint. I’ll try that.

Your hint of trying AxesOrigin worked. Thanks!!
