I'm trying to compute some statistics on a given range of data from a plot using a bokeh app. For selecting the range I am using RangeTool. However I cannot find the way to detect the event. I'm using as base this example:
https://docs.bokeh.org/en/latest/docs/gallery/range_tool.html
Then I tried:
def func():
print(range_rool._property_values['x_range'].start)
return
def func_e(event):
print('event detected')
return
range_rool.on_event(ButtonClick,func_e)
range_rool.on_event(Press,func)
range_rool.on_change("x_range",func)
but when I move the slider I don't see any difference. Any idea very welcome. Thanks
The RangeTool updates the range it is configured with, you can (and should) just add callbacks on the range itself, e.g.:
range_tool.x_range.on_change('start', ...)
Regarding the line range_rool.on_change("x_range",func) that you have, it's worth explaining that that instructs Bokeh to run func when the range object itself is wholesale replaced, i.e.
range_tool.x_range = some_new_Range1d
would trigger that callback. But the range is never normally replaced liked that. Instead, the start and end values of a single range are updated over time.
Also, as an aside, there is never any valid reason at all to access _properties. It is a private API and subject to change at any time.

I am doing a simulation of a production line, which is built through Excel.
Now there is one, which needs free setting of worker shifts for each machine, three shifts in total.
My idea is to create three different Schedules, representing each of the three shifts, and then in the ResourcePool, use the If statement to set up the use of each shift. As shown in the picture enter image description here
But it didn't work. If it is possable, Could you please tell me if there is something wrong with the Java statement or the idea is wrong.
If possible, could you please tell me how to set multiple schedules in ResourcePool?
Additions to the question：
The model is to do the evaluation of the production system and the shift of the workers is an important evaluation parameter. What I want to do is to enter the shift of the workers directly in the Excel sheet and ResourcePool recognizes and uses the corresponding Schedule.
I tried to generate the corresponding Schedule by code, but the Schedule of Resourcepool cannot be set dynamically. So I would like to try to manually input multiple Schedules into the model and then set the corresponding Schedule in ResourcePool by If statement like the image.
Thanks in advance
The first thing you need to know is that the location where you placed the code is a static parameter, thus it is only evaluated once, when the object is created and not checked continuously.
This is indicated by the little popup when you hover over the button that change the entry field from code to value
If it was dynamic it would state Dynamic Value instead of Static Value
Secondly, inside that field you must use a ternary operator, not an if statement, so that the result of the formula is a scheduled object, else you will get a "misplaced construct(s)" error
If you changed the code to
v_Shift == "Shift1" ?
s_Shift1 : v_Shift == "Shift2" ? s_Shift2 : s_Shift3
It will work BUT:
It will only be evaluated when the object is created and not again
Rather not use == on Strings, always use .equals(), on Strings it might work, and sometimes it might not. You can do some research as to why ;-)
Solution: You will have to use a function to change the schedule of the resource pool. Call this function whenever the v_Shift variable changes
I did try using the RS_VARIANT_CONTENTS and RS_VARIANT_VALUES_TECH_DATA, it did show the values of the variant except the values of the name space, interface and interface version in which I also need to retrieve. I also searched the VARI* and TVARC tables but I didn't found it there.
I think it has something to do with the program name and screen number. Do you have any ideas or other way that I can retrieve all those values, whether using FM or select?
Thank you.
Some of the parameters in the transaction /AIF/ERR, the ones you are talking about, vary dynamically based on the value chosen in the Application screen field. They are handled by another AIF program, and they are not saved in the program variant, but in the table /AIF/T_ERR_VARS.
You may call the function module /AIF/ERR_VAR_LOAD to load the missing parameters.
Its usage is shown in the subroutine GET_VAR of the program /AIF/ERROR_HANDLING_TRANS (which is the program behind the transaction /AIF/ERR).
Images can be displayed at a specific location with the DisplayAt() command.
Does anyone know the valid range?
For example, DisplayAt(-9000, -9000) is that valid? What is the total valid range?
Of course in the example the image would not be seen within the GMS frame, but that is exactly what I need.
Thanks
Yes, negative values are completely ok and will indeed "place" the image outside the visible range of the window.
There is nothing like a "valid" range - the coordindates are just numbers. ( There is likely a limit when the value exceeds the value-range of the internallly used variable type to store the coordinates, possiblye long (4 byte signed integer). )
Just be aware that concepts like "front most" window will also apply if an image is outside the "visible" range. Images will f.e. also show up in the ImageBrowser regardless of their position on the workspace. The same is true for iterating through images on a workspace using f.e. CountImageDocuments() and GetImageDocument()
Some commands ( I think ShowImage() ) might have addtional code to ensure that images stay "visible" and might therefore shift the image back into the workspace range. Also using "auto-arrange" will take images from the "off" and place them back into the visible range.
So if you deliberatly use "off-screen" display, this is ok, but it might create some unintended side-effects. What is the exact purpose of using it this way? There might be more suitable concepts. (f.e. one can create imageDocuments and add ImageDisplays to them without the need of showing the imageDocument.) Image may also be temporarilly "hidden". Finally, one might condiser shiftung "unwanted" images onto a separate workspace.
I am trying to send the value of a response time (e.g. key_resp_2.rt) to a later routine.
I am new to PsychoPy and am unsure how to do this. I have been unsuccessful searching Google for an answer...
A later routine can refer to previous variable by name in a Code component. i.e. in that code component, you could insert code like this, say to update a text stimulus depending on a previous reaction time:
if key_resp_2.rt < 0.200:
myTextStim.setText("Well done, quite fast.")
But you would need to specify what you want to do to get more specific help.
Cheers.
I have code that requires a ParasiteAxis instance, or at least something with a toggle_axisline method, in order to function properly. I'd like to be able to pass it any arbitrary axis created in any way (e.g., through a simple plot call).
How can I convert any given axis instance into a ParasiteAxis or HostAxis instance?
(for a specific use-case, see issue https://github.com/aplpy/aplpy/pull/88 and specifically the workaround implemented in commit https://github.com/keflavich/aplpy/commit/02ecd5386f7d3a93ca8e60c3db2b34ff3216060a)
