I have recently introduced myself to Max, and have came to halt. My situation is - I am using jit.gl.gridshape to draw simple vertical lines into a matrix, along the x, y position. This matrix is then being displayed onto a lcd screen.

In order to place a vertical line on the left hand side of the matrix, I must use @position -1 0 0. The problem here is, I need to set the 'left hand' side to be 0(x), 0(y), 0(z), meaning the 'right hand side' will be 2(x), 0(y), 0(z).

The reason for this is, I am sending audio sample point values to Max from Pure data and scaling them to fit . But, can only position these lines from 0(x) upwards, which is the right half of the matrix.

It's hard for me to tell exactly what you mean, but if it's a matter of needing numbers to be converted from the range 0 to 2 in one context to the range -1 to 1 in another context, just subtract 1 from all the numbers. But probably you mean something more complex than that, so the best way to get help with that is to post an example of what you've done so far and explain how the results you currently are getting differ from the results you want to get.

Thanks for the Response. I've posted my patch below.

I'm trying to plot transient points with vertical lines along a visual audio waveform. These points are coming from Pure Data. Now if I try to plot the sample point 3452 of an audio file, and scale it proportionally, I get 0.022503.

What I want, is to have a matrix where 0.022503 is visually at the beginning of my matrix waveform, as opposed to just being slightly halfway. Is there an easy way to do this?

Hmm. Looking at your patch, it seems to me as if it really IS as simple as just subtracting 1, right after your [* 1.9] object.

Here's my revision of the right side of your example patch.
