[R-SIG-Finance] Change Size of Axis and Labels in chart.RollingPerformance in package PerformanceAnalytics

[Idris Raja]

I'm trying to change the font size of the axis labels in the chart from
"charts.RollingPerformance" in the PerformanceAnalytics package without any
luck.

I've tried:

require(quantmod)
require(PerformanceAnalytics)
data(managers)
# tried various cex options like cex.lab, cex.axis, cex.ylab... none seem to
work
charts.RollingPerformance(managers, cex.lab = 2, cex.axis=2)

As you can see from the included picture, the default labels are way too
small. I'm guessing this is something easy but not obvious. Does anyone know
how to do this?

Thanks
