Errors in x-axis

Errors in x-axis

Hello,

In Mathcad 15, is it possible to add error bars to the x axis of a plot? I have a data series of 10 x values and 10 y values. The error in y is 0 however there are individual errors in each x values and I am wondering if it is possible to add horizontal error bars.

Any help would be appreciated.

I am wondering if it is possible to add horizontal error bars.

Not that I am aware of.

Would a transposed plot, plotting x over y instead of y over x be an option?

Unfortunately not, it's an x-y phase diagram for adsorbed mole fraction on an adsorbant surface unfortunately. Also as I'm trying to compare the empirical results (data series) with those found using IAST I have had to use a solve block so want to plot that on the same curve, which is why I am wanting to do it on mathcad rather than grace or excel.

Thanks anyway.

So you may consider creating your own error plot if the data is in vectors. You will also have the benefit of more control over line thickness.

I wrote some functions to do this. I have posted these before, but can't find the thread. See the attached.
