MUON: cannot plot from result table

[Anders Markvardsen]

1. Do sequential fit of MUSR15189-15199.

2. Open Results Table and create table selecting Run Number, CountRate and Field_Danfysik.

3. In the table, select any Y column and CountRate column. A correct plot gets created.

4. Select any Y column, CountRate column and Run Number column. Plot is empty.

5. Select any Y column and Field_Danfysik column. Plot is empty again.

Wasn't able to reproduce it. After doing what is described in 4. the plot does get created.

With a bit of help from Anders was able to reproduce the problem. It appears when we have both X and L columns in the table.

Refs #8678. Fixed and refactored addCurves method.

Y column are now added to the beginning of the list of drawable columns so that they are drawn first and can be later found to attach error and label columns to.

Switch statement is used now instead of a bulk of ifs.

Refs #8678. Fixed colIndex method.

It was assuming that column names shouldn't have underscores in them, which was not always true. A bit cleverer approach is now used.

Tester:

There were two main problems causing the described scenario to happen:

1. Nothing was being drawn when we had column with plot type Label.

2. Column have not been used when it had underscores in its name, e.g. Field_Danfysik.

So the task is to check that those problems were fixed. Follow the described steps and make sure plot in 4. does have Run Numbers as labels and plot in 5. uses Field_Danfysik as X.

Checked changes have fixed the listed issues. Code code changes look good too.
