heatmapcore.js uncaught TypeError

[RoJoRZ]

Dear,

I am facing an error which I don't understand. I have a D3heatmap plot which works in the Rstudio viewer. But it does not show whenever I want to show it in a shiny app (neither local as on the server). This plot was until recently working perfectly. Looking in the error log I noticed this error in heatmapcore.js:

// Hack the width of the x-axis to allow x-overflow of rotated labels; the
// QtWebkit viewer won't allow svg elements to overflow:visible.
xaxis.style("width", (opts.width - opts.yclust_width) + "px");

Uncaught TypeError: xaxis.style is not a function

Can this be the reason of me failing to plot my D3heatmap or should I look into other options? Any help would be appreciated as I seem to got stuck here.

Thanks, Ronny
