When switching between algorithms in S(Q,w)

[Lottie Greenwood]

In S(Q,w), if you plot the output as a spectra graph and have over a certain number of spectra, a dialogue appears to make sure you are certain. However, if you already have a spectra plot up that was created by a different algorithm, even if you click cancel, it will have already overwritten that graph with the newly calculated spectra plot. In this circumstance the dialogue is effectively useless.

To reproduce:

• Open Indirect > Data Reduction > S(Q, w)
• Load input file: irs26176_graphite002_red.nxs
• Q binning: 0.6, 0.1, 1.8
• Energy binning: -0.5, 0.05, 0.5
• Plot output = spectra
• Run with one Rebin type, leaving the spectra plot window up
• Run with other Rebin type, click cancel on dialogue and note the plot has changed anyway

Will look at in #8236.
