Graphing 2D X-Y in MathCAD: Fixing Axis Scale Issues

In summary, the conversation discusses the issue of equal scale option not working properly in MathCAD when graphing 2D X-Y. It is mentioned that there is no function to make minor divisions on axes equi-distant and the equal scale option only sets the scale numbers equal. The conversation also touches upon using Maple 8 to draw graphs and the difficulty in exporting them as dxf in 2D. The conversation concludes with the mention of fixing the distance issue by turning off Autoscale and turning on Autogrid. The reason for needing equal axis scales is also mentioned.

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?

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.
 

FAQ: Graphing 2D X-Y in MathCAD: Fixing Axis Scale Issues

How do I fix the scale of the x and y axes in MathCAD?

To fix the scale of the x and y axes in MathCAD, you can use the "Axis Properties" tool. Simply click on the x or y axis, then right-click and select "Axis Properties." From there, you can manually adjust the minimum and maximum values for the axis scale.

Why is my graph in MathCAD not showing the full range of my data?

This could be due to automatic scaling by MathCAD. To fix this, you can use the "Axis Properties" tool to manually adjust the minimum and maximum values for the x and y axes. You can also try changing the type of scale used, such as logarithmic or linear.

How do I change the labels on the x and y axes in MathCAD?

To change the labels on the x and y axes in MathCAD, simply double-click on the axis labels and type in your desired labels. You can also use the "Axis Properties" tool to customize the labels and font size.

My x and y axes are not crossing at the origin. How do I fix this?

To fix this, you can use the "Axis Properties" tool to manually adjust the location of the axes. Simply click on the axis, then right-click and select "Axis Properties." From there, you can change the position of the axes to cross at the origin.

Can I add a grid to my 2D graph in MathCAD?

Yes, you can add a grid to your 2D graph in MathCAD by using the "Axis Properties" tool. Simply click on the axes, then right-click and select "Axis Properties." From there, you can check the box next to "Grid" to add a grid to your graph. You can also customize the grid lines and spacing using the options provided.
