mouse cursor secondary axes

[<pl...@pi...>]

Hi,

I wanted to display secondary axes on 'mousing' feature of SVG terminal. 
Specifically I have a plot line on x1y2 which I need to see displayed on 
the floating cursor readout.

It is displayed on the cursor under the graph when second y2 is used 
but not on the text box which follows the cursor.

I looked at modifying the relevant gnuplot_svg.js file to modify fn 
gnuplot_svg.updateCoordBox()

this includes the following for y1 coordinatte:
  label_y = plotcoord.y.toFixed(2);


I was expecting a plotcoord.y2 abut this does not seem to be defined. I 
started backing and duping code but it was getting more complex than I 
expected.

Am I missing something here or did x2y2 not get included when this 
feature was added?

Tnanks, Peter.
