I'd like to overlay a scientific form number on a ListPlot at a particular position.

Simply using Text[ToString@value, {xpos,ypos}] separates the exponent from the number and increases the font size. I found several posts about exponential notation for axes labels etc but I've not found one for this. I think one way would be to somehow convert the ScientificForm object into a Graphics object, then I could place it anywhere.

I think this must be a duplicate question as it seems so fundamental but I'm clearly searching for the wrong expressions!

  • $\begingroup$ Thank you MarcoB! Inset is exactly what I needed. Inset[value,Scaled[{xpos,ypos}]]; $\endgroup$

  • $\begingroup$ As an example, you could use Epilog -> Inset[Style[ScientificForm[N@value], Red, FontSize -> 14], Scaled[{xpos, ypos}]] to have control over the color, font size, positions, etc. of the text you want overlaid. $\endgroup$

    $\begingroup$ @march. That's not a good coding example. The use of string operations in generating the label is totally unnecessary. One can just use Row. $\endgroup$

You can use the Text graphics primitive to place a ScientificForm expression anywhere in a graphics pane without resorting to string conversion. For example,

  Text[Style[ScientificForm[N[Pi 1*^10], 8], 14, Bold, Red], Scaled @ {.5, .9}]}]



I didn't bother to introduce Epilog here, but Text expression like this one are perfectly acceptable in a list of graphic primitives given to Epilog.
