No slrealtime​.Instrumen​t.LineStyl​e in R2020b:

Hi,

I was looking at the documentation (R2020b) for "Instrument" and the following example was added to the explanantion of using it:

---------------------------------------------

ls2 = slrealtime.instrument.LineStyle();

ls2.Marker = '*';

ls2.MarkerSize = 4;

ls2.Color = 'black';

inst.connectLine(app.Axes1, "SineWave", 'ArrayIndex', 5, 'LineStyle', ls2, 'Callback', @(t,d)(d+app.Offset.Value));

---------------------------------------------

This seems to say that a LineStyle can be associated with an slrealtime.instrument object. I used the same for an slrealtime.instrument object in my App and got the following error message:

-----------------------------------------------

The class slrealtime.Instrument has no Constant property or Static method named

'LineStyle'.

Error in UECUStim_NNP_Realtime/setupInstrumentation (line 207)

app.linStyl = slrealtime.Instrument.LineStyle();

-----------------------------------------------

Am I missing something? Please help.

slrealtime.instrument.LineStyle is not the same as slrealtime.Instrument.LineStyle. From the error message you're using a capital-I in that command rather than a lowercase-i. It's a similar type of problem as below (but the difference between s and S is easier to see.)

s1 = sin(pi) % works

s1 = 1.2246e-16

s2 = Sin(pi) % errors

Unrecognized function or variable 'Sin'.

Good catch!

That works! Thank you very much.

If I may, could I please ask a follow-up question? In my App, I defined all my instrument objects with an uppercase 'I' as in: app.hInst = slrealtime.Instrument(app.modelName); and everything works perfectly; except for that LineStyle aspect. Are there two different classes - one named 'instrument' and the other named 'Instrument'? I hope I am not doing something wrong using the uppercase 'I' version?

Thanks.
