Hi @spoony,
>> Instead of plotting 3 charts, I need to plot a single bar chart and with a slicer elsewhere to select which of input, output or combined appear on the chart individually or together.
You can write a measure with the slicer to show the display one of these value, but I don't think it support to show them together, value field only support value type.(if input the text string, it will auto convert to "count of xxx")
Measure sample:
SelectedItem= If(Hasonvalue(Table[Column],Values(Table[Column]),Blank()) Displayed=If([SelectedItem]="abc",Max(Table2[Input]),If([SelectedItem]="def",Max(Table2[output]),Max(Table2[combined]))
BTW, legend not support measure, calculated column not support to dynamic change result with slicer. So I think current it impossible to dynamic change the legend field.

See the discussion at "Using slicer to choose which dimension to display". I beleive that it is relevant to what you are trying to accomplish.
My suggestion would be to use a clustered column chart with the following setup:
