f(x)=a*x+b
fit f(x) m using 3:2 via a,b
func=sprintf("y=%.2f*x+%.2f",a,b)
set terminal svg background "white"
set key left top
plot f(x) title func with lines, m using 3:2 title 'points' with points
\(n\) 计算

g(x)=a*x+b
fit g(x) n using 3:2 via a,b
func=sprintf("y=%.2f*x+%.2f",a,b)
set terminal svg background "white"
set key left top
plot g(x) title func, n using 3:2 title 'points'

f(x)=a*x+b
fit f(x) Ea using 3:5 via a,b
func=sprintf("y=%.2f*x+%.2f",a,b)
set terminal svg background "white"
set key left top
plot [x=0.00325:0.0036] f(x) title func, Ea using 3:5 title 'points'
