1. *Give me every Heat treatment* (Wärmebehandlung)
2. Multi-select **and**: *that has a realizes*, *that has an output*
3. Click on *realizes* to change the focus
    1. *a plan* → *that has a concretizes* → *a recipe* → *that has a part (bfo:\*51)* → *a scalar value specification* → 
Multi-select **and**: *that has a specified numeric value*, *that has a measurement unit label*
4. Click on *an output* to change the focus
    1. *an object* → *that is the input* → *a separation* → *that has an output* → *an object* → *that has a state* → *an object*
7. Now we need to get a characteristic twice. We can achieve this by:
    1. *that has a characteristic*
    2. change focus back to the last *an object*
    3. Multi-select **and**: *that has a characteristic* (Just one property)
8. Change focus to the first of the *has a characteristic*
    1. *a Tensile Strength* → *that has a concretizes* → *a scalar value specification* → Multi-select **and**: *that has a specified numeric value*, *that has a measurement unit label*
9. Change focus to the second of the *has a characteristic*
    1. *a Proof Strength Plastic Extension* → *that has a concretizes* → *a scalar value specification* → Multi-select **and**: *that has a specified numeric value*, *that has a measurement unit label*

Now the Heat Treatment Temperature, Tensile Strength and Yield Strength (Proof Strength Plasit Extension) should show in the nested table below.

If we wish to plot the results:
1. Switch to the *YASGUI* tab
2. Switch to the *Pivot Table* tab below
3. Change the Chart Type to *Scatter Chart*
4. Find the relevant *specified numeric values* on the left. These should be some OBI_\*. You can double-click on one of them to inspect the values, which might give a hint. (E.g. 850, 925, 1000, ... are probably values of the Heat Treatment Temperature)
5. Move them into the *Columns* or *Rows* regions (E.g. Heat Treatment Temperature into *Columns* and the strength values into *Rows*)

1. *Give me every object* → *that derives into...* → an object
2. We need to get object twice (it derives into the test piece and the metallography disc):
    1. Change focus back to *every object*
    2. Multi-select **and**: *that derives into* (Just one property)
3. Change focus to *something*
    1. *an object* → *that has a quality* (expand *that has a characteristic* with the small triangle to the left of it)  → *a Mean Planar Grain Diameter* → *that has a concretizes* → *a scalar value specification* → Multi-select **and*: *that has a specified numeric value*, *that has a measurement unit label*
5. Change focus to *an object* (the other object from the Muli-select)
    1. *that has a characteristic* → *a Proof Strenght Plastic Extension → *that has a concretizes* → *a scalar value specification* → Multi-select **and**: *that has a specified numeric value*, *that has a measurement unit label*

For plotting results see above.

Opening links may be difficult on some browsers. If you accidentally click on the link and it becomes part of the query, click once on the white left-arrow in sparklis. Place your mouse in the top-left corner of a cell with a link, so that the link isn't highlighted. From here it should be possible to mark the link with left-click and dragging the mouse.
