I created a shiny application which draws timeseries data in a single dygraph plot.
If the dygraph is rendered at once, any arbitraray number of time series can be plotted in one graph.
But if I add additional timeseries by use of dySeries command, there seems to be a limit of 10 total numbers of series to be plotted. If, for example 8 series are drawn initial and 3 series are added by
g <- dySeries(g, c('lval','value','hval') ....) to get a shaded curve of a new time series with low- and high values, the following error appears:
Error in <-: 'names' attribute  must be the same length as the vector 
I tried some combinations of numbers of initial series and by dySeries added, the error only appears, if the total number exceeds 10.
This happens when the newest dygraphs versions are used (22.214.171.124 or 126.96.36.199), but works as expected when dygraphs 188.8.131.52 is used.
Are there bugs introduced in the newest versions of dygraphs ?
