Discussion Overview

The discussion revolves around issues related to graphing 2D X-Y plots in MathCAD, specifically focusing on the equal axis scale feature and its effectiveness. Participants also touch upon related graphing challenges in Maple 8, particularly regarding 3D to 2D graph conversion.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant notes that the equal scale option in MathCAD does not produce perfect squares on the grid when the graph window is resized, leading to confusion about its functionality.
  • Another participant explains that MathCAD lacks a function for equidistant minor divisions on axes, indicating that the graph is merely stretched to fit the window size.
  • A participant inquires about converting 3D graphs in Maple 8 to 2D, expressing confusion over the 3D representation and seeking a method to view only the x-y plane.
  • One participant shares a personal solution to the axis scaling issue in MathCAD by turning off Autoscale and enabling Autogrid, which they claim results in perfect squares on the grid.
  • Another participant asks for clarification on where to find the Autogrid option within MathCAD's interface.
  • A later reply provides guidance on accessing the Autogrid option through double-clicking the graph window or using the right-click Format tab.

Areas of Agreement / Disagreement

Participants express differing views on the functionality of the equal scale option in MathCAD, with some finding workarounds while others remain uncertain about the best approach. The discussion about Maple 8 also shows a lack of consensus on how to effectively convert 3D graphs to 2D.

Contextual Notes

Limitations include the lack of clarity on the specific conditions under which the equal scale feature fails and the potential dependency on user interface familiarity in both MathCAD and Maple 8.

When graphing 2D X-Y in MathCAD there is an option to make the axis scale equal, but it doesn't seem to work like I want it. If the axis scales are equal, then the grid should always make perfect squares, but it doesn't. Especially if you start dragging the sides of the graph window. How can this be fixed?
 
Computer science news on Phys.org
MathCAD has no function to make minor divisions on axes equi-distant. The graph will be stretched to fit in the size of the window you make by grabbing and stretching the region it is in. The equal scale option simply sets the scale numbers equal. It doesn't effect the sizing.
 
Thanks FredGarvin! Say, I trying to use Maple 8 to draw graphs, and then export them as dxf. This export is only possible when the graph is in 3D, but I only need 2D. I get a little confused when seeing 3D graphs (lol), is there any way I can "convert" the 3D graph to 2D, so that only the standard x-y plane is visible? I first thought I could just "turn" the graph window around to accomplish this, but I wasn't able to. Hope you can help me...
 
I have not had the chance to play around with Maple. I can't really help you there. I have been thinking if there is some way to do what you are looking for, but I can not get the equidistant graduations like you are looking for. Is there any particular reason you need this?
 
I actually managed to fix that distance thing myself. If I just turned Autoscale off and Autogrid on, the the grid always makes perfect squares. The reason I want this is that if the axis arent't equal that gives you a false impression of what the graph looks like, especially if you aren't aware of it. But thanks anyway!
 
Where is the Autogrid option found? Under the properties tab?
 
No, I just double-click the graph window and a bunch of options appear. Also you can right-click on it and use the Format tab.
