I have two columns, let say x and z of 30 points. Where z is depth and should be shown in vertical axis. And if I can show it downward, it will be perfect. I use x,y (scatter) to draw the chart which is OK but Z appears in horizontal axis but I want it to be shown in vertical axis. Simply it looks like I want to rotate the chart 90 degrees. How can I exchange z and x values in the chart?
