R Shiny GoogleVis missing axis labels from squashed bar charts -

my shiny app not showing vertical axis labels in bar charts. have looked @ other answers show labels on horizontal axis , google chart not showing x-axis labels.

test data plot in data.table labels a,b,c,d, etc.. numeric values.

please see gist whole app.

so 1 gets (chart a) can see barchart labels skipping letters:

when want (chart b) showing , b , c , d etc... on y axis:

i setting width , height "automatic" in first chart charts scaleable on different size screens. worked fine few months rendering above. chart b done forcing chart width , height numeric values.

k.op.width  <- "400"  k.op.height <- "400" 

this not wanted wanted make full use of screens possible , viewable on tablets.

i setting googlevis vaxis option showtextevery:1 @asgallant suggested in comments answer above, not helping. wide screen crimping plot area, truncating chart. why chart not spread downwards in size showing labels?

is there way these charts in shiny show labels without forcibly setting chart height?

p.s. using googlevis_0.6.2 data.table_1.10.4 shiny_1.0.3 on r 3.3.3
