slider config

[User002]

hello, 

i have a slider which varies from 0 to 63 as shown in image now i want to make like it should show on front panel 0 to 504 but in background it should send 0 to 63 for example on front panel 0, 8, 16, 24, 32, 40, 48.... 504 in multiples of 8 but in background(block diagram)  it shound send 0,1,2,3,4,5,6,7......63 so it can be 0=0, 1=8, 2=16,3=24,4=32......, 63=504.. how can i do it ?

thank you

Well, how about dividing by 8 before you "send" it along?

That leaves you with the decision of how to handle remainders.   You've told us that (for example), 0 on the front panel maps to sending 0, 8 maps to 1, 16 maps to 2, etc.  So what do you want to do with 1-7, 9-15, etc.?

You also have a subtle endpoint problem looming.  You should probably have 64 size-8 *intervals* so your slider's full range should go from 0 to 511 (while you can make the scale on the display lie to suggest that it goes from 0 to 504, assuming you have a good reason for presenting things that way to the user)  Going from 0 to 504 only gives you 63 full intervals.

    If you range it 0 to 511, you can use the integer quotient and remainder directly to do the right kind of divide-by-8 mapping with equal size intervals.

thanks but the next problem is i have other sliders in that one has 5 values 8,10,24,456,5640 on front panel and in block diagram it should be 0,9,50,118,185.. so 8 on front is 0 in block diagram, 10 is 9, 24 is 50,256 is 118, 5640 is 185.. so may be i need other solution..

waiting for replies

thank you

So now you have a completely different problem!?

Use a lookup table: have your slider output (integer) values of 0-4 and use those to index an element of any array holding your desired output values!

sorry but can you show me example or link of example because i did not get you exactly.

thanks

As I wrote before: use text labels for your slider and an array of your desired value!

So why exactly does it have to be a slider? Seems quite misguided and a complete waste of UI space. It's just not natural!

I would recommend a "ring", "radiobutton control", or similar.

Here's something to get you started , but solves a slightly different problem. You just need to adapt it!

Note that for rings, the item and values can be anything you want!

If the number of items gets too long, I would use a listbox with a scrollbar. Use a double-click event to index into an array of values.

thanks for different idea but i want to adjust it with slider so user can adjust the config easily because in other slider there are more than 600 values.

I managed to do it with suggestions. Now i have one last question regarding this sliders. the Same slider i which is varies from 0 to 504 configuration is done now i want to add one last functionality in it. If slider value is 0 to 63 it should jump the values by 1 and if slider crosses 63 then it should jump values by 8 then multiplication value should change from 1e-6 to 8e-6 and there is one string that should change. i tried to do it it is working but im using button and cases i dont want to use that it should select automatically. im attaching the vi in this there are two while loops which show the what i want to do and i third while loop i did it using selection button.

waiting for suggestions thank you..
