Pixel or line choice

Targets Windows
1

For a project I want to mimic the little ‘output’ graph that appears in the Apple Music app on the current track. First I thought that it responds to levels in the track but it doesn’t, it just randomly shows moving bars, though very fluid.

My initial idea was to use three different timers that each build a bar according to a random height. Wat is the best way to doe this. Drawing the individual bars myself or use Line with a thickness of say 3 pixels?

Sub Paint(g As Graphics, areas() As REALbasic.Rect) // Window dim micro as double = Microseconds g.PenWidth = 3 for rounds as integer = 1 to 10 for i as integer = 0 to self.width step 3 G.DrawLine (i, 0, i, g.Height ) next next system.DebugLog "Line "+str(Microseconds-micro) micro = Microseconds g.ForeColor = &c00800000 for rounds as integer = 1 to 10 for i as integer = 0 to self.width step 3 G.FillRect(i,0,3,g.height) next next system.DebugLog "fillrect "+str(Microseconds-micro) End Sub

FillRect seems faster after a few runs.

Wow. You had that code handy I guess :slight_smile:

Thanks
