## Viewing Recorded Data
|
|
|
|
To view recorded data, Trick provides an application called **quick plot**.
|
|
**NOTE:** The GUI or plot graph figures may be shown differently on your
|
|
machine due to the differences of the platforms and ongoing changes.
|
|
|
|
### Using Trick Quick Plot
|
|
Begin by launching trick-dp (trick data products GUI).
|
|
|
|
```bash
|
|
% cd $HOME/trick_sims/SIM_cannon_analytic
|
|
% trick-dp &
|
|
```
|
|
|
|
#### Plotting Time -vs- Position
|
|
1. Double click the pathname containing your sim directory (or single
|
|
click the symbol next to the name)
|
|
1. Double click the `SIM_cannon_analytic` name in the Sims/Runs pane.
|
|
This will reveal the `RUN_test` directory.
|
|
1. Double click the `RUN_test` name. This will bring `RUN_test` into
|
|
the RUN Selections pane below.
|
|
1. Click the blue lightning button in the tool bar to launch quick
|
|
plot (qp). The qp GUI will pop up.
|
|
1. In qp, right click the `dyn.cannon.pos[0-1](m)` variable in the
|
|
left pane and choose **Expand var**. Next double click `dyn.cannon.pos[0](m)`.
|
|
This sets up qp to create one page with one plot (time -vs- pos[0]).
|
|
1. Now click the `dyn.cannon.pos[1]` variable and drag it to the pane
|
|
on the right. Drop it on the line with "Page" (see the white-n-black window
|
|
looking icon). This will result in one page containing two plots.
|
|
1. In qp, click the plain white sheet icon located on the toolbar. A
|
|
single window with two plots should pop up. (See Figure 4)
|
|
1. When you are done with the plots you created, close the **Trick
|
|
Plot** window which will also close the window with your plot(s).
|
|
|
|
|
|
|
|

|
|
#### Plotting XPosition -vs- YPosition
|
|
1. Right click "Plots" in the "DP Content" pane and choose
|
|
"Remove All Pages".
|
|
1. Double click dyn.cannon.pos[1].
|
|
1. Drag-n-drop the dyn.cannon.pos[0] variable over
|
|
the sys.exec.out.time variable in the Plot located in the "DP Content" pane. You
|
|
will be asked to confirm the replacement. Click "Ok".
|
|
1. To see the plot, click the white sheet icon on the toolbar. Voila!
|
|
There is the trajectory! :-) Note that the cannonball goes underground. This
|
|
will be fixed later.
|
|
1. When you are done, close the **Trick Plot** window.
|

#### Creating a DP Specification File
|
|
Repeatedly clicking variables in Trick QP gets old, fast. To get around this,
|
|
the information needed for this plot will be saved to a file named
|
|
`DP_cannon_xy`, and then reused by `trick-dp`. This is an important step,
|
|
because extensive use will be made of the `DP_cannon_xy` file.
|
|
|
|
1. With the Trick QP GUI still up and the x -vs- y position still
|
|
chosen, click the `dyn.cannon.pos[1]` variable located in the pane on the right
|
|
(in the DP Content pane). The variable should be highlighted. The **Y Var**
|
|
notebook page should be visible in the lower right pane.
|
|
|
|
1. In the **Y Var** notebook page, select **Symbol Style->Square**
|
|
from the drop-down menu.
|
|
|
|
1. In the **Y Var** notebook page, select **Symbol Size->Tiny** from
|
|
the drop-down menu.
|
|
|
|
1. Click the **Apply Change** button (you may have to scroll up to
|
|
see the button).
|
|
|
|
1. Save this information by clicking the menu option **File->Save As**.
|
|
Click **New Folder** button to create the `DP_Product` folder. Choose the
|
|
directory button `SIM_cannon_analytic/DP_Product`. Enter file name as `DP_cannon_xy`.
|
|
|
|
1. Close the **Trick QP** GUI, but keep Trick DP up and running.
|
|
|
|
#### Using trick-dp To View Data
|
|
Now that `DP_cannon_xy` has been saved, the data can be viewed with trick-dp.
|
|
|
|
1. Assuming the **Trick DP** is still up and running from the
|
|
previous steps, click **Session->Refresh…** to reveal `DP_cannon_xy.xml` in
|
|
the top right pane, **DP Tree**.
|
|
|
|
1. Make sure that `Sims/Runs->SIM_cannon_analytic/RUN_test` shows up
|
|
in the **Run Selections** pane. If not, then double click it to add it.
|
|
|
|
1. Choose the `DP_cannon_xy.xml` in the top right pane by double
|
|
clicking it. This will bring the `DP_cannon_xy.xml` into the **DP Selections** pane.
|
|
|
|
1. To see the trajectory again, click the plain white single sheet
|
|
button on the toolbar. Zoom in by holding the middle mouse button and drag
|
|
across a section of the plot. Then release the mouse button. Notice that there
|
|
is a tiny square on each x-y point recorded.
|
|
|
|
1. Once you are finished with the plot, close the **Trick Plot**
|
|
window and Trick DP.
