Auto minimum on Y Axis
 

Hi all - If someone can help me here I would be most grateful. I have a
chart which plots values over a time period of say 15 years. The value
is entered in one cell and then a macro is run to generate the returns
for each of the 15 years which the chart then plots.

The problem is when the fund value is high say 1,000,000 originally and
the returns are low, then it doesnt change much, but the Y axis starts
at 0 so there is a massive gap and then you can't see much differential
in the line graph.

I have tried changing the chart options, but as the returns are
variable I can't put it in a minimum.

Any ideas??

Thanks

I suspect you must have considered it but the large range sounds
just what a log axis is meant for. Do you have any negative
values that might cause trouble with logs?

some of the return %'s are negative values, but the line will never go
into a negative value on the Y Axis - is this what you mean? I'm not
sure what a log axis is

Thanks very much

Basically, it is an alternative to a linear scale on the y-axis.
Click the chart/Right click y scale/Format axis/Scale/select
logarithmic scale. I hope I am not being excessively pedantic
:-) Give it a try; you can always reset to a linear scale.

Again, being pedantic again, the logarithm of a negative number
is imaginary.

Hi - thanks for your reply, but the logarithmic scale doesn't help as it
makes it go haywire. I think the fact that the variables on the x axis
can vary so greatly it goes off the screen sometimes
