2d-plot

[Raj_mathcad]

I do not see any option to change the graph reference to 0 instead of 1(see attached) for a 2d bar plot with log scale on �y�.
Is it possible?

Log(1)=0 which is what the graph is showing.

Since the log of zero does not exist, zero is not a valid value for a log scale plot.

Your plot looks weird and log scale is a display that falsifies the perception. Those peaks looks like some sort of wavelets or some kind of histogram. Without the maths of the plot, can't help +.

Your plot looks a residual plot, a plot that does not need to be Y log scale. For the line 1 to be zero, plot ordinary. If you have problem to "appreciate", then plot 1-Y/f(X) if the matter is residuals. What do you think showing a graph w/o the maths that plot ? Logarithms of any base don't evaluate at 1, at that value (1), 0 is a conventional value.
