Help with axes tick labels PROC Template

Hello All,

The code below was posted by JeffMeyers and it was super helpful. But I need help increasing the font size of the x- and y-axis. The font size in the output graph is small.

data work.Almtarfi_2;
input Cult Biomass_BRC Biomass_RB yield_BRC Yield_RB Height_BRC Heigh_RB;
CARDS;
1930 62.125 75.255 2563.16 2196.06 123.075 142.8
1933 60.62 77.91 2396.49 1965.79 106.233 124.325
1935 51.275 77.2 2317.14 2490.56 114.75 137.25
1940 63.31 73.025 2738.19 2888.38 142.85 169.5

Add to the Xaxisopts or Yaxisopt

labelattrs = (size= fontsize)

font size (without the <could reference a Style attribute, to change as your ods style changes, or a number and dimension unit of measure such as CM, MM, IN ( Inches), PT (points) PX (pixels) or PCT.

Pixels change in relation to display/image type so can be a tad flaky to set.

Thanks for the suggestion. I made the following additions but the tick labels did not change and I did not receive any error in the log. The additions are in bold.

xaxisopts=(display=(line ticks tickvalues) labelattrs=(weight=bold size=30pt family="Arial"))
yaxisopts=(display=(line ticks tickvalues) labelattrs=(weight=bold size=30pt family="Arial"));

Any suggestion?
