chore: add measured and calculated data for DiffractionObjects example? #345
Description
Problem
The DiffractionObjects example doesn't have any data associated with it so you can't run the example past this point (which is very early in the example) because xcalc, ycalc, xmeas, ymeas are not defined.
calculated = DiffractionObject(xcalc, ycalc, "d")
measured = DiffractionObject(xmeas, ymeas, "tth", wavelength=0.717)
plt.plot(calculated.on_q()[0], calculated.on_q()[1])
plt.plot(measured.on_q()[0], measured.on_q()[1])
plt.show()
solution
Find and add some data!

does the data in
\diffpy.utils\doc\source\examples\example_data\not work? This is hard to find and probably not described in the docs well enough, but if it works we can use it.cadenmyers13 commentedon Jun 12, 2025
@sbillinge not for the DiffractionObjects example. that one is missing data.
sbillinge commentedon Jun 12, 2025
but my question was that none of those example datasets will work? Not if they are all gr. In any case we just need some iq file from some project. Please do what you can!

@cadenmyers13 I have found what you said in the
rstfile, but I'm unsure what we need to do at this stage. Should we find the relevant data to fill it in to the place of the parameter to make it work?sbillinge commentedon Nov 26, 2025
@cadenmyers13 pls can you work with @stevenhua0320 to get this closed?

@sbillinge No problem. @stevenhua0320 I just sent you over slack 2 CeO2 files. one is .chi and one is .fq. Im not sure which one fits this example better here (my guess is .chi). you should be able to add that to this example

Could you send it again on Slack as seems I did not receive it
