Hi, someone could help me to plot a graph that show the function value under the cursor?
For example in the image below if the black point is cursor it will show (-0.5,2)

If you are using IJulia, then you can do this with Plots.jl and plotly:
using Plots
plotly()
plot(linspace(-1, 1).^2)
And if you’re using Plots with Juno, the plotlyjs()
backend will do it. Just swap out that plotly()
command. And if you’re at the REPL, plotlyjs()
will give you a GUI window with that interactivity, while plotly()
will open it in a browser.
The InspectDR
backend was built with this kind of interactivity in mind:
InspectDR.jl
: https://github.com/ma-laforge/InspectDR.jl
Eventually, the intent was to have the cursor track the plot data so that all displayed coordinates are meaningful, but for now, all features are “floating” in the plot window.
Plots.jl
:julia> Pkg.checkout("Plots")
Just remember to eventually restore Plots.jl to its most recent “tagged” version once Tom (the maintainer of Plots.jl) creates a new release:
julia> Pkg.free("Plots")
Would it be possible to read out the cursor positions (x,y) which are displayed in the active PyPlot-window in order to use the values for further tasks? And how can I manage this?
