sql server reporting services: I have developed a scatter chart and have set bot the the x-axis and y-axis
scales manually. However neither the minimum nor the maximum are being
respected. I am not trying anything complicated, just trying to set some
blank space around the plotted data so that the plot points don't go right to
the edge of the graph area. Is this a know issue or am I doing something

Are you seeing this error when running the report from the report
itself? or off the .NET file?

If the error only shows up when the you runnig the report from the ASPX
file, Look at the ASPX file you may have some heights and widths that
are messing with your boundries.
