bodeplot not showing plot after 10^2

[naeem6100]

ControlSystems v1.5.3

using ControlSystems
setPlotScale("dB")
sysc1 = tf(1000000000,[47,0])
fig= bodeplot(sysc1, plotphase=true,label="Capacitor-1",xlims=(1, 10^4),ylims=(-150, 150))

That looks like an issue with Plots.jl or GR, have you tried plotting with plotly as backend?

I have plotted "using Plots" with gr()

using ControlSystems
using Plots
gr()
setPlotScale("dB")
sysc1 = tf(1000000000,[47,0])
fig= bodeplot(sysc1, plotphase=true,label="Capacitor-1",xlims=(1, 10^4),ylims=(-150, 150))

Running this code in google colab using "Julia Colab Notebook Template"

how to use plotly as backend?

Install Plotly.jl and then call plotly()

Isn't it just that you change xlims without increasing the frequency range? I think there is a w keyword for bodeplot allowing you to do that, though not at a computer now so haven't tried.

so it is applying default frequency vector by calling _default_freq_vector which is using default range from 10^0 to 10^2
Thanks!

following code is doing the job.

using ControlSystems
using Plots
gr()
setPlotScale("dB")
nw = 60*(7)
# frequency vector
fv= exp10.(range(0, stop=7, length=nw))
sysc1 = tf(100000000,[47,0])
fig= bodeplot(sysc1, plotphase=false,fv,label="Capacitor-1",xlims=(1, 10^7),ylims=(-150, 150))
