How to plot two different line plots using geom_line and, especially, geom_area

Question

I'm asking for your advice and support to plot two lines of data using the geom_line and geom_area f(x) in Rstudio. It's pretty simple, but I can't fix the bugs from the final plot. I will appreciate your help!

The code that I'm using is described as follows:

`ggplot(data, aes(Strain,Stress, colour=Treatment))+ geom_point(aes(), size= 1.5, linetype="dotted")+ geom_area(aes(), alpha=0.2)+ xlim(0,0.01)+ylim(0,0.003)+ theme( line = element_line(colour = "black", size = 1, linetype = 1, lineend = "butt"), rect = element_rect(fill = "white", colour = "black", size = 1, linetype = 1), aspect.ratio = 1, plot.background = element_rect(fill = "white"), plot.margin = margin(1, 1, 1, 1, "cm"),

axis.text = element_text(size = rel(2.5), colour = "#000000", margin = 1), 
strip.text = element_text(size = rel(0.8)), 
axis.line = element_blank(), 
axis.text.x = element_text(vjust = 0.2), 
axis.text.y = element_text(hjust = 1), 
axis.ticks = element_line(colour = "#000000", size = 1.2), 
axis.title.x = element_text(size = 30, vjust=0.5), 
axis.title.y = element_text(size = 30, angle = 90), 
axis.ticks.length = unit(0.15, "cm"), 


legend.background = element_rect(colour = NA), 
legend.margin = unit(0.15, "cm"), 
legend.key = element_rect(fill = "grey95", colour = "white"), 
legend.key.size = unit(1.2, "lines"), 
legend.key.height = NULL, 
legend.key.width = NULL, 
legend.text = element_text(size = rel(2.0)), 
legend.text.align = NULL, 
legend.title = element_text(size = rel(2.0), face = "bold", hjust = 0), 
legend.title.align = NULL, 
legend.position = "bottom", 
legend.direction = NULL,
legend.justification = "center",
legend.box = NULL, 


panel.background = element_rect(fill = "#ffffff", colour = "#000000",
                                size = 2, linetype = "solid"), 

panel.border = element_rect(colour = "black", fill=NA, size=2), 

)+ ylab("Stress(MPa)") + xlab("Strain")`

The result is a estrange plot:

The expected images is the two plot in the same graph, where the x and y scales are the same, like a good way to compare. The expected plot is shown:
