thist - a go package for calculating online histograms with plotting to the terminal and images
===============================================================================================
[](http://godoc.org/github.com/bsipos/thist)
[](https://goreportcard.com/report/github.com/bsipos/thist)
Example
-------
```go
package main
import (
"fmt"
"github.com/bsipos/thist"
"math/rand"
"time"
)
// randStream return a channel filled with endless normal random values
func randStream() chan float64 {
c := make(chan float64)
go func() {
for {
c <- rand.NormFloat64()
}
}()
return c
}
func main() {
// create new histogram
h := thist.NewHist(nil, "Example histogram", "auto", -1, true)
c := randStream()
i := 0
for {
// add data point to hsitogram
h.Update(<-c)
if i%50 == 0 {
// draw histogram
fmt.Println(h.Draw())
time.Sleep(time.Second)
}
i++
}
}
```

TODO
----
- Add more details on online histogram generation.
- Add separate object for online estimation of moments.
- Maybe add tcell as a back-end?
