Hiding Specific Data Labels in Julia Plots
Code 1
using Plots
x = rand(30)
y = rand(30)
z = rand(30)
plot(x)
plot!(y)
plot!(z)
png("result1")
In some cases, you might want to make only certain data labels appear in the legend, as shown above.
label = ""
plot(x, label = "")
plot!(y)
png("result2")
In such cases, you can set the option label = "". As you can see, the first data is displayed in the figure, but it does not appear in the legend.
primary = false
plot!(z, primary = false)
png("result3")
Another way is to set the primary = false option, as shown. The last data is plotted in orange and hidden in the legend. Since this is a side effect of turning off primary, it’s better to only tweak the label option if possible.
