straight line on semi-log graph

[dhoangz]

hi, I'm trying to graph an array of 500 points on a semi-log graph. The line look right on the Linear Scale but it curves a little bit when I changed to Logarithmic scale. How can I make it a straight line on the logarithmic scale? please see attachment

There's nothing you can do short of changing the data--or the scaling of the x axis. What you're seeing is an effect of the y-axis scaling.
