"E" for powers of 10

Emmerich38 — Fri, 23 Feb 2024 08:46:20 GMT

Hello,

For a publication in a scientific paper I made graph under JMP (file attached). Editor asks me to change the "E" for powers of 10. In other words, 3.4 × 10⁵ instead of 3.4e+5. Could you please tell me if there is an easy way to do this ?

Thanks in advance,

best regards

Sébastien

Hi Sébastien,

with JMP 17 the best way would be to copy a vector graph into another graphing program and change the axis as you need it.

JMP 18 will be released in a couple of weeks with an option for scientific notations to make this natively possible in JMP.

Hope that helps.

Jonas

Local( {supers = "⁰¹²³⁴⁵⁶⁷⁸⁹", d, parts},
	parts = Words( Format( value, "Scientific", width, dec ), "e" ); // split on e
	Substitute Into( parts[2], "+", "", "-", "⁻" ); // ignore +, superscript -
	For( d = 0, d <= 9, d++, // superscript each digit
		Substitute Into( parts[2], Char( d ), Substr( supers, d + 1, 1 ))
	);
	if (value == 0, "0", parts[1] || " × 10" || parts[2]); // add x10 unless 0
)

Hi. There was a previous discussion on how to achieve this: https://community.jmp.com/t5/The-Plot-Thickens/Reply-All-Scientific-notation-such-as-6-02-10-using-custom-axis/ba-p/559110. Essentially you use the script above to replace the e numbers with the x10 format. The link is to that previous discussion which gives more details.

You can use a JMP 17 custom format to do it. (Test this code to make sure it does what you want!) Copy this

If(
	Pat Match(
		Format( :value, "Scientific", :width ),
		Pat Pos( 0 ) + Pat Immediate( Pat Break( "e" ), f ) + "e"
		+Pat Immediate( Pat Rem(), e )
	),
	f || "⨉10" || Substitute( e,
		"+", "⁺",
		"-", "⁻",
		"0", "⁰",
		"1", "¹",
		"2", "²",
		"3", "³",
		"4", "⁴",
		"5", "⁵",
		"6", "⁶",
		"7", "⁷",
		"8", "⁸",
		"9", "⁹"
	),
	Char( :value, :width, :dec )
)

Then open the axis dialog, Format->custom, set custom, paste.

(view in My Videos)

The custom format uses the scientific format to make the "e" format then parses the fraction and exponent. It then reassembles the number with some Unicode characters. If you are not seeing exponents and multiplies and signs, your font might not include them. If the parse step fails, the custom format falls back to the char() function.

Hi @Emmerich38 @Craige_Hales @Jonas_Rinne : and, this was discussed here recently.

Nice, wished I new that earlier...

just leaving this here in case someone is looking into this thread after the JMP 18 release:
