Hey all,
I'm drawing a graphing line, looks like a wave within an NSView. The
line looks fine, except that it's not scaled to the size of the
window. So my problem is trying to figure out how to scale it to the
window size and every time that the window is resized.
I currently have something like below, but my 'scaleXBy, yBy' on the
NSAffineTransform isn't working out so well.
Anyone see what I'm doing wrong here, or know how to get the
NSBezierPath to take up 90% of my NSView (leaving 10% blank for
borders which is what I tried to do below)?
- (void) drawRect:(NSRect) rect
{
NSRect bounds = [self bounds];
float xAxis = bounds.size.width * 0.9;
float yAxis = bounds.size.height * 0.9;
[[NSColor blackColor] setFill];
[NSBezierPath fillRect:bounds];
NSAffineTransform *newTransform = [NSAffineTransform transform];
[newTransform translateXBy:40.0 yBy:30.0];
[newTransform concat];
// can't seem to get this transform to work as expected.
[newTransform scaleXBy:xAxis yBy:yAxis];
[self drawAxes:rect width:xAxis height:yAxis];
[self drawGraph:rect];
return;
}
