# Log Log Excel charts

## Log Log Excel charts

(OP)
Hi,

Is it possible to have excel insert a chart that has BOTH the X axis AND the Y axis in log form?

Sure, are you having a problem with that?  You'd need to select the scatter plot for the graph format.

Yes I'm having trouble.

I can get a log y axis vs linear x axis but can't seem to get Log y & Log x.

How is that done?

Thanks

Joe

### RE: Log Log Excel charts

You need to select the x-y scatterplot.

You probably selected the line chart.  The line chart only has a category x-axis, not a numerical x-axis.

Transform your formula to logY=MlogX+logB then you can use the line chart method

### RE: Log Log Excel charts

No you can't.

Do it and you'll find out why it doesn't work for XY data.

Cheers

Who can't?  Plotting with the XY scatter will allow for X and Y log scale.

### RE: Log Log Excel charts

You can't use a line chart as Rjeffery suggested, unless your data is already at logarithmcially equal intervals.

Gemtlemen,

Thanks.

I finally understand that the xy chart is fundamentally different from the line chart.

I tried the xy scatter chart, and there, it was duck soup.
