问题 I have an image like this, with a rectangle at specific coordinates: (for illustratory purposes I put the coordinates of the rectangle and its size and center in there) Now I want to render some text with ImageMagick, so that it fits exactly within the rectangle . If it's a very short (narrow) string, the rectangle's height will be the limiting factor: On the other hand with a long (wide) string, the rectangle's width will determine the size: In either case, independent of how short or long

Why does my linear regression fit line look wrong?

问题 I have plotted a 2-D histogram in a way that I can add to the plot with lines, points etc. Now I seek to apply a linear regression fit at the region of dense points, however my linear regression line seems totally off where it should be? To demonstrate here is my plot on the left with both a lowess regression fit and linear fit. lines(lowess(na.omit(a),na.omit(b),iter=10),col='gray',lwd=3) abline(lm(b[cc]~a[cc]),lwd=3) Here a and b are my values and cc are the points within the densest parts

Why doesn't my regression line look more like that on
