Plotting: Optionally plot counts/width

[Martyn Gigg]

Add an option to plot the counts/bin width for 1D plots in MantidPlot. This will help mostly in situations where the binning is not regular.

I found this script useful for creating test workspaces

uniform_bins = CreateSampleWorkspace()
non_uniform_bins = Rebin(uniform_bins, Params="0,300,10000,500,20000")
point_data = ConvertToPointData(uniform_bins)
non_uniform_bins_distrib = non_uniform_bins.clone()
ConvertToDistribution(non_uniform_bins_distrib)

Branch: ​feature/10639_plot_distribution_option

Tester: This concerns how data from a spectrum plot is displayed by default. After these changes the default for a histogram plot will be to display the values normalized by the bin width. This will not change the original data, just affect how it is displayed.

I used the script in comment 19 to create a variety of workspaces with different characteristics:

• A histogram with uniform binning;
• A histogram with non uniform binning;
• A point data set and
• A histogram that is already a distribution.

Try plotting these and see that in the first 2 cases the default is now the plot counts/microsecond but for the last 2 the plot detects that either no normalizations is appropriate or it has already been applied.

For those that have been normalized automatically you can right-click on the plot and choose to change to normalization with a new option. Verify that this works as expected.

There is also a global option in View->Preferences->2D Plots that controls how histograms are plotted by default. Check that this works and is saved/reloaded between MantidPlot sessions.

Reopened due to a few issues: only the first should be dealt with in this ticket, the others have new tickets.

1. If you plot errors, whether by plotspectrum with errors, or the graph->add error bars -> from workspace, they are not scaled by the bin width and therefore overpower the data.
2. The interaction with fitting is confusing as you setup the plot against normalized data, but it fits against the underlying non normalized data. - Follow on ticket to deal with this #10668.
3. We need to make sure the default is set "correctly" for this release - Follow on ticket to determine this and implement #10669.
