I am working on drawing graphs on the terminal itself from inside a go code.I found this (https://github.com/gizak/termui) in golang. And used this(https://github.com/gizak/termui/blob/master/_example/gauge.go) to draw graph in my code.
Problem is this , as we can see in the code( https://github.com/gizak/termui/blob/master/_example/gauge.go ), they are passing g0,g1,g2,g3 all together in the end "termui.Render(g0, g1, g2, g3, g4)". In my case I don't know how many gauges to draw before hand so I used a list to store gauge objects and then tried to pass list to render.
termui.Render(chartList...)
But it creates only one gauge.
This is how I am appending elements in the list.
for i := 0; i < 5; i++ {
g0 := termui.NewGauge()
g0.Percent = i
g0.Width = 50
g0.Height = 3
g0.BorderLabel = "Slim Gauge"
chartList = append(chartList, g0)
}
what I am getting is a gauge for i=4 only. when I am doing termui.Render(chartList...) Am I doing something wrong? PS - I have modified question based on the answer I got in this question.
