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.<div><br></div><div>I've tried:</div><div><br></div>
<div>require(quantmod)</div><div>require(PerformanceAnalytics)</div><div>data(managers)</div><div># tried various cex options like cex.lab, cex.axis, cex.ylab... none seem to work</div><div>charts.RollingPerformance(managers, cex.lab = 2, cex.axis=2)</div>
<div><br></div><div>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? </div><div><br></div><div>Thanks</div>
