Having trouble changing the y axis scale

[#1]

I am working on a graph of Voltage vs Current. I have my y axis (current scale) set to log and i want to change the scale to the format 10e-2 (for example). Everytime I try to do this, the graph scale to 1e-1. I need the scale to be in the notaion 10e not 1e. Can anyone hlep with this?

Hi @hannahmcnamara,

You can have complete control over the format if you specify a custom format for the axis, like this:

Script to recreate graph:

Names default to here(1);

//Make some example data and specify a couple values to check results
dt = New Table( "Example Data",
	Add Rows( 1000 ),
	New Column( "Data",
		Numeric,
		"Continuous",
		Format( "Best", 12 ),
		Formula( Exp( Random Uniform( 1, 100 ) ) ),
		Set Selected
	)
);
dt:Data << Delete Formula;
dt:Data[1] = 1;
dt:Data[2] = 10;

//In graph builder choose the log scale and then specify a custom format
gb = dt << Graph Builder(
	Size( 822, 339 ),
	Show Control Panel( 0 ),
	Variables( X( :Data ) ),
	Elements( Points( X, Legend( 25 ) ) ),
	SendToReport(
		Dispatch(
			{},
			"Data",
			ScaleBox,
			{Scale( "Log" ), Format(
				"Custom",
				Formula( "10^" || Char( Log10( value ) ) ),
				12
			), Min( 1 ), Max( 1e+45 ), Inc( 1 ), Minor Ticks( 0 )}
		)
	)
);

Thank you! This worked for me. I was wondering how you get the double line symbol before "Char"?

Good question because it took me a while to figure out how to do that interactively too.  If you type the upper bar character '|' in the formula editor you will first get the or symbol, then if you type it again you will get the concatenate operator '||'.  Also, if you double click on the formula it will open a text editor where you can type the two upper bars.
