Plotting data of deedle data frame with Xplot plotly

问题

I have a Deedle data frame with DateTime values as key and two columns with data. Now I want to plot the data of column 1 with a Scatter chart from Plotly.

I am using FSLab and there is XPlot.Plotly 1.3.1 included.

But I can't use Plotly:

open XPlot.Plotly.Graph
open XPlot.Plotly
open XPlot.Plotly.HTML

let dataFrame = ...

Scatter(
  x = dataFrame.ColumnKeys,
  y = dataFrame.GetColumn("col1")
)
|> Chart.Plot
|> Chart.Show

I'm getting this error: "The field, constructor or member 'Plot' is not defined.

Do I am missing something?

回答1:

Not sure what is the latest version of XPlot but I get 1.4.2 in nuget. So, to make things simple I avoided all the FSLab magic this time:

//#load @"..\..\FSLAB\packages\FsLab\FsLab.fsx"
#r @"..\packages\XPlot.Plotly.1.4.2\lib\net45\XPlot.Plotly.dll"
#r @"..\packages\Newtonsoft.Json.9.0.1\lib\net45\Newtonsoft.Json.dll"
open XPlot.Plotly
open XPlot.Plotly.Graph

let layout = Layout(title = "Basic Bar Chart")

["giraffes", 20; "orangutans", 14; "monkeys", 23]
|> Chart.Bar
|> Chart.WithLayout layout
|> Chart.WithHeight 500
|> Chart.WithWidth 700
|> Chart.Show


let lineTrace1 =
    Scatter(
        x = [1; 2; 3; 4],
        y = [10; 15; 13; 17],
        mode = "markers"
    )

lineTrace1 |> Chart.Plot   |> Chart.Show

Now, this will plot the charts in the browser. I believe you can bind it to WPF or winforms as well.

Edit

As this works for you, but you still need FSLab, the easy way out is to replace the XPlot.Plotly.dll and xml file in ...\FSLAB\packages\XPlot.Plotly\lib\net45.

Then you can call XPlot.Plotly without the need of referencing directly the dll.

#load @"..\..\FSLAB\packages\FsLab\FsLab.fsx"
open XPlot.Plotly
open XPlot.Plotly.Graph
open XPlot.Plotly.Html

let layout = Layout(title = "Basic Bar Chart")
["giraffes", 20; "orangutans", 14; "monkeys", 23]
|> Chart.Bar
|> Chart.WithLayout layout
|> Chart.WithHeight 500
|> Chart.WithWidth 700
|> Chart.Show
