Drawing Plot error

I have R which contains 27 matrics all of them have the same corresponnding depth ( ztips). I want to draw all of the matrics in one plot instead of having 27 plots.

I tried the one Mr. Werner suggested before. However, it doesn't work here. I guess the mistake is that ztips and R are different types.

The sheet is too long and I can't just substract R because it is the final result of all the above calculation. Sorry for this trouble

Your R.s;cal;B is a vector of vectors. You cannot use that in a plot.

Success!

Your worksheet contains a lot of errors as of not defined variables, so I can't test it myself.

But it may help if you replace "stack" by "augment" and omit the NaN

And of course you should plot R over Z and not R.s;cal

Is the worksheet you posted the latest version and the one that you are working with? I couldn't get your worksheet to run properly without making a few modifications. Primarily, you try to take last(ztips), implying ztips is a vector but you define it as a range variable (= z_tips), so I used my vec function to change ztips into a vector - that seemed to get rid of most of the errors, but I don't know how many more I might have thrown up by doing so.

However, your prime(!) problems are that you are trying to plot R_s;cal;B against z_tips.

z_tips is a range variable, so Mathcad expects to see it used in both axes. Did you mean to use (NaNized) ztips with a section of ztips equal in length to each section of R_s;cal;B? I note you only have 10 ztips values but 27 R_s;cal;B values.

Although, you calculate R_s;cal;B you don't assign the NaNized vector version to R_s;cal;B, you assign it to R instead.

That still doesn't give the plot I think you want.

Nor am I sure this is what you want. It matches an R section against each ztips value, which effectively plots the range of forces for each depth (ie, it's a horizontal line). It may be useful as a summary of some kind.

Multiplying a vector by zero is a time-honoured Mathcad method for getting a zero-vector of a desired length without the hassle of worrying about exactly what length you need.

However, if it is the plot you want, then there is no need to plot the entire pressure vector for each depth. You only need the min and max pressures, which simplifies the whole business.
