problem with graph control fontsize

Hello,
I am having trouble with the vb 6.0 graph control. I can get my data graphed correctly, but my x and y axis labels are too small to read. I have tried using all the different font properties, but nothing seems to work. I have made my graph as big as possible and this doesn't change anything either. I have a total of 127 data points on a line graph with the ranges of the xaxis = 0-4400 and the y-axis 0-400. If you could please give me some input on what I am doing wrong, or what I could change I would greatly appreciate it.

Thank You
