Woooooo so I figured out how to draw wave forms to graphic windows now my question is. How can I make this work ? I have run into issues while resizing the graphic array "tab" to fit its own window bounds. The normal way I would have gone about this would be to use a [cords....] object to adjust the bounds for the sub-patch but because I'm dealing with a graphic window a error is thrown stating the array can not be found.

The second screenshot is the result of a newly drawn wave form. You can see that whenever a new wave is loaded with a different sample length it has to be resized.

I should mention currently array1 is being resized correctly the problem is the graphic array "tab"
Any help or direction is appreciated.

After a new wave is loaded.

@RetroMaximus mapping might help
map.pd
map-help.pd

Yes this is correct but how do i set the x range for a graphic array. If you happen to look at the patch I do have 2 arrays in total. One named array1 which is the main that "tab" the graphic array gathers data from. I tried using a variation of not this exact code but something similar I quickly copied a snippet as a example. And at that time the graphic array "tab" could not be found. So I thought the x range could not be set this way. If this is the right way to do it?

And now that I look at this screen shot the cords message would have been corrected to [s pd-WFormLine] and not [s pd-PlotControl]

tab does exist inside the struct i forgot to open it for the screen shot.

@lacuna Thx im going to dig in now.

@RetroMaximus Yes, with [coords( to pd-WFormLine with 300 x 150 size, but 0 to sample size x-range should work.

Or with [donecanvasdialog( if coords don't has the range, not sure right now...

That way you would not need dynamic patching. You can try it manually with the properties dialog of the subpatch.

@RetroMaximus Here is how you can change the canvas size (which you don't want to do) and dynamically create a new [plot] object to the new scaling.......

If you have not found another way.
Dynamic patching is very simple for objects like [plot] that have no connections to be remade after re-creation.

@ingox I was setting x range manually while testing I found that if I divide the total samples by 500 and used the result as the x-range value everything fit perfectly for every sample loaded. I just didnt know how to make it happen through a message.

I didnt know at the time of [change vis-size 0 $1< Im going to give that a shot now.

@whale-av While this is a heck of a lot cleaner then what i have down. It is partially incorrect I don't need to change the vis-size for the canvas as this is already being set in a smaller subpatch. I need to adjust the "visual size" of a graphic.

In other words what message can I use to change the x-range for pd-WaveFormLine.

as @ingox mentioned it might be [donecanvasdialog(

Whoooooooo it was [donecanvasdialog< Thanks sooooo much for the input guys!! you guys rocked it once again! @ingox @whale-av

Muchhhhh cleaner!.

@RetroMaximus Yes, and it might also work with x-spacing in plot 1 instead of 0.002 and not dividing the value by 500. Should be the cleanest way.

@RetroMaximus I have only now had the time to test it: You can even define a field in the struct where the array is defined and use this field inside [plot].

In this example the array size is also the number of points that are drawn. When the number is changed, the x-spacing of plot is set to fit the points inside the subpatch:

structarray2.pd

Wow well this can also work as a zoom type of utility also. very cool.

I think I'm going to scrap what I have and use your patch as it is sooo much cleaner and just by the way its structured alone give me a few other ideas.

This is great yesterday I got stuck trying to "make things better" drawing the start queue and end queue positions "the green rectangle" to where now only the very first sample point gets selected. Then in return when i click the play button the player stops instantly because the end position has been reached. All because I thought I should change the scale value to 1 when I don't think i had to, Now the play positions seams to start at 1 and go to 1.9 instead of 0 to 0.9 I don't know what I did. lol

You patch will solve my current problem in pretty sure. Thank you soo much once again!
