Prime 6 does not appear to have a way to produce a grid on a 2D plot. Without a grid, plot values are difficult to read. Hopefully this glaring omission will be corrected in Prime 7. It would be good to have major and minor grid lines, of different colors and weights, but as a minimum the plotting features of MathCAD15 should be included. A related helpful feature would be to be able to control the orientation of polar plots. A current need is for a polar plot with zero degrees pointing to the left rather than to the right, with positive angles opening counterclockwise. One could imagine zero degrees straight up, with positive angles opening clockwise, or other orientations and directions.

I posted this before and got a response to the effect that showing a grid is possible in Prime6 by way of some kind of plot editor. But I can't find any such thing anywhere in Prime6. If some tool is to be used, it would be helpful to know where to find it.

Solved! Go to Solution.

Hi,

On the ribbon under Math | Regions | Chart Component is a drop down list, select Insert chart component.

Set the x and y values you get a plot.

Double click the plot opens up a whole plot editor where you can set X and Y gridlines.

Cheers

Terry

Hi,

You can set a polar plots orientation see fie below.

Re: Grid on a 2D Plot

Yes, I know, in mathcad 15 or less..

But in Prime, and WITH a grid?

Re: Grid on a 2D Plot

Thank you! Strange that this is "hidden" and not under the "plots" tab where one would look to find things about plotting. But the capability is exactly what I was looking for.

Re: Grid on a 2D Plot

Not so 'strange':

The 'chart component', which does feature grid lines, is a badly integrated third party add-on.

Re: Grid on a 2D Plot

We need grid for papier plots, not for a live plots with markers. I think so!

a) Not just (physical) paper plots, but any non-live Mathcad plot, such as an image in an on-line article.

b) Adding markers is a mandraulic(*)/ трудоемкие(?) task. IME, it's cognitively less challenging to glance across a grid.

I like Prime's extra horizontal and vertical markers, but I'm not at all sure that they are the better choice for skimming through an article and picking up information at a glance.

Re: Grid on a 2D Plot

To show what could be done with a little ingenuity, attached is a file (courtesy of Luc and Werner, IIR) that draws grids **and works in Express**

Re: Grid on a 2D Plot

For a grid, I was thinking more like this:

With possible variations (Start and end of both radius and angle can be set) such as:
