Log axis crossing

I have a log-log plot. The y-axis range is 0.01 to 1.0. The problem is that the x-axis is labeled at the TOP of the y-axis.

Is there a way (as there is in EXCEL) to change where the x-axis labels are placed (i.e. - I want the labels to be at the lowest y value (on log scale) of 0.01)?

Double-click on the plot, select the "X-Y Axes" tab on the resulting dialog (should be the default tab anyway), then change the "Axis Style" at the bottom of the tab to "Boxed".

Which version of Mathcad are you using and could you post an example worksheet.

I don't know how to add the example, but this is the plot.

Removing the log scale from the Y-axis will also do the job.

In Mathcad 15 (and below) there is unfortunately no way to change the point of intersection of the two axis.

This point will normally be (0/0) or (if zero is not in the range shown) the values closest to zero.

In case of a log plot the 0 is exchanged for 1 and the point of intersection tries to be at (1/1).

In case of your plot the intersection point is (100/1).

I guess you may like the view when you change Axis Style from Crossed to Boxed:
