@d-healey So How can I make custom LAF Matrix peak meter with gradient.

[d.healey]

@DabDab Without doing it for you there's not much more to say. This is the function I'm using, perhaps it will give you some guidance.

    laf.registerFunction("drawMatrixPeakMeter", function(g, obj)
    {
    	var a = obj.area;
    	var value = 0;
		var numActive = 0;
		
        for (x in obj.peaks)
        {
			if (x > 0)
			{
				numActive++;
				value += x;
			}	        
        }

        value = value / numActive;

    	g.setColour(obj.itemColour);
    	g.fillRoundedRectangle(a, 8);

    	g.setColour(Colours.withAlpha(obj.itemColour2, 0.2 + value));

		if (a[2] > a[3])
		{
			a[2] *= value;
		}
    	else
    	{
	    	a[1] = a[1] + a[3] - a[3] * value;
	    	a[3] *= value;
    	}
    	
    	g.fillRoundedRectangle(a, 8);
    });

@d-healey Oho... really complicated scripts. It was beyond my knowledge database..

Thank you so much.

[d.healey]

@DabDab It's not complicated, it just looks it at first. This handles vertical and horizontal meters in my project.

[DabDab]

@d-healey Yes.. I am going through the code.

@DabDab said in Help "drawAnalyserBackground", "drawAnalyserPath" "drawAnalyserGrid",:

@d-healey Yes.. I am going through the code.

My code is also to draw a single bar with the average of all channels. That's what this part does.

for (x in obj.peaks)
{
    if (x > 0)
    {
        numActive++;
	value += x;
    }	        
}

You don't need that if you want to display each channel individually or if you have a mono signal.

[DabDab]

@d-healey Ok.. got it. (y)

[clevername27]

@DabDab I have done so - a highly detailed LAF documentation and tutorial. look in the repository…wherever they put it. It's where all the contributions go…I just don't remember off the top of my head.

[DabDab]

@clevername27 Can you please put the url here ?

[clevername27]

@d-healey Just to add the David's comments, depending on what you need, it can be simply to add LAF parameters by modifying HISE's C++ code. For example, I posted a while back about adding the component name to LAFs for specific widgets.

[clevername27]

@DabDab I have written and posted Peak Meter LAF documentation, and a tutorial, this week on the forum.

[DabDab]

@clevername27 Ok.. Sure.. (y)

[aaronventure]

@DabDab can these be used to do the work on the goniometer?

I'd like the dots to remain on screen and fade out over a few dozen milliseconds, so that it looks like they're leaving a trail.

[d.healey]

@aaronventure No I don't think we have any control from the scripting API (except usual properties) over the appearance of this component.

[aaronventure]

@d-healey Oh man, I already have like 3 requests open. :face_with_tears_of_joy:
