How do i add a point in a chart

[MySchizoBuddy]

I want to add a specific point F(1) on a rectangular plot. but doing that gives me a horizontal line. I want to highlight certain points in the graph.

[MikeArmstrong]

Something like the attached?

So i put my points in a X and Y vector and plot those.

Let me try

[MikeArmstrong]

You could post a worksheet showing an example of what you want.

This is what i have so far. look at the attachment

How do i remove the lines connecting the crosses

[MikeArmstrong]

That can be done.

Can you post the Mathcad worksheet?

Just double click on the graph, select Traces, select Points as the "Type"

He could also use the "Lines" function attached and plot the real and imaginary parts instead of inputting the vectors into the graph.

Have a look at the attached worksheet. I know Eden has helped with the question but this is a different method to creating vectors and putting directly onto the graph.

On another note. Upload worksheets in M11 format for a wider audience.

I simply put the x and y coordinates of the point on the respective axes, select a symbol, give the symbol enough weight to be seen and change the line type to points. See one of the plots in the attached file

To ensure the maximum audience post your worksheets in M11 format.

Dixie,

While that is another option and probably the most basic, simple in my eyes is good. If the variables in the graph change you would have to manually change the numbers in the graph yourself.

Quite right Mike,

I refrained commenting because in my opinion Dixie's suggestion was too primitive considering all the tools I plug in this collab. Like you say: manually assigning the points is not the way in real projects where you want the points to be computed. I have clearly realised that most of the *.xmcd has little interest unless from some old collabs.

Cheers Mike,

Don't miss "Tangent, normal, Curvature, Radius of"

It might help in your "pipeline" project.

Cheers Jean,

Just downloaded the "Tangent, normal, Curvature, Radius of" worksheet.

If the coordinates of the point to be plotted are computed, give them variable names and use variable names instead of the number. That way the point is plotted properly if the coordinates change

Dixie,

That is an improvemnt from what you originally suggested, but what happens if you have 10 points to plot? Define 10 variables?

I was assuming here that we were talking about 1 or 2 points that are being used to specify a particular point on a curve. For multiple computed points I insert variable names in a matrix, if possible, see attached. If the variable values change the points are still plotted properly

[jeanGiraud]

More for your tool box & enjoyment.

Nice example Dixie.
