Danfo.js plotting support for latest version

[risenW]

Hi @DonJayamanne

Thanks once again for supporting Danfo.js in the Nodejs notebook. It works very well for Danfojs v0.2.7

Sadly, plotting does not work for the latest version (v0.3.3). I am curious as to how you're supporting plotting directly from the danfojs-node, as we did not package it with Plotly features.

Did you write a custom renderer for this? And if yes, how do we support the latest version of Danfojs.

If there's any way I can be of help, do let me know.

Cheers, and great work!

@risenW
Looks like DataFrame.plot method has been removed in the latest version
Let me see where that is now.

Yup, thats not showing up in the latest type definitions. curious, was that deliberate?
https://danfo.jsdata.org/api-reference/plotting/timeseries-plots

Something like this would not get completions even if targetting web

new_df = df.set_index({ column: "Date" })                
new_df.plot("plot_div").lin

Or has the plotting API changed?

I had over wrote the Datafarme.prorotype.plot method with my own implementation.

Yea, we took it out of the Nodejs version. It only ships with the browser version.

Oh I see. Do you have a suggestion for fixing this without adding back the plot module to the Nodejs version?

[DonJayamanne]

only ships with the browser version.

How do you make the distinction. I could be using danfo.js in a web app with typescript, now I won't get any competitions
, And would assume that it's not available in browser either?

I'd suggest adding it back and when the plot method is executed you check whether it's the browser or not and throw an error if it's not running in the browser.

Thanks for the suggestion. I'll do that, and let you know.

I use "danfojs-node": "^1.0.4" and get this error - which looks like it again does not support plot in node:

Error: Not supported in NodeJS
    at DataFrame.plot (../node_modules/danfojs-node/dist/danfojs-base/core/frame.js:2363:19)

my code:

try {
  df.plot("plot_div").scatter({
    config: { x: "rating", y: "detailview_count" }
  })
} catch(e) {
    console.log(e)
}

danfojs-node examples are failing as well.

Some methods are renamed in the latest version of danfojs.

read_csv -> readCSV
set_index -> setIndex

The plot method does not work and I end up using plotly directly.

It is a great work!
Thanks a lot for the plugin!

[DonJayamanne]

Fixed, in the latest version, will release soon

Was testing this today in VSCode. Showing this error when I try to run the example:
