Improve the precision of object placement on charts
Since Excel 10, the precision of placed objects like lines on charts has deteriorated. For example, drawing a 45 degree line on a chart from one corner to the other is very imprecise because it seems the cursor has trouble picking up the correct pixel in the chart axes corner. Sometimes the chart has to be resized to nail the placement down.
Thanks for the feedback. Would you be able to provide a sample file that illustrates the problem or more specific repro steps?
Just to be clear, are you drawing a line from the corners of the plot area; i.e. top of x axis to far right of y axis, or are you drawing a line from the corners of the entire chart area?

The simplest thing is to create a chart, say, a scatterplot.Now try to draw a line from one corner to the other. More often than not, one or both
of the ends of the line is outside the intersection of the X- and y-axes.
