v9 Alpha1 - fail to init()

[jpotton]

Hey there,

Just becoming familiar with the library so forgive me if these are noob questions. 2 Questions:

1. I'm playing with v9 alpha1, invoking from pure JS and having difficulty creating chart instance. It appears because "data" var is undefined in failing method, the .timestamp attribute therefore doesn't exist and bombs.

2. v8 -> v9 migration notes state I should be importing like so:

"klinecharts/index.blank' and klinecharts/index.simple are no longer distinguished. Please use import {...} from klinecharts uniformly
https://github.com/liihuu/KLineChart/blob/main/docs/en/v8-to-v9.md

Having plenty of issues with that import method in pure js. Am I doing something wrong or is that type of invokation only required for Vue/React etc..?

Instead i'm having to use

<script src="/static/js/kline_charts/klinecharts.js'></script>

Thanks in advance,
Jeremy

How did get klinecharts.js?
Data must contain some fields. https://klinecharts.com/guide/data

You need to do this to introduce through script,

klinecharts.init(...)

Thanks for taking time to reply...

klinecharts.js came from:

npm install
npm run build
./dist/klinecharts.js

klinecharts.js v9.0.0a1 is served from python:flask

Here is my code (simplified to get to the bottom of this issue).

<div id="chart_div"></div>

<script src='/js/klinecharts/klinecharts.js'>
    window.onload = function() { 
        kchart = klinecharts.init('chart_div'); 
    }
<script>

This code creates the above exception because data is undefined. Exception occurs before I can call any of these:

• kchart.loadMore(loadmore_cb_func)
• kchart.applyNewData(klines, true)
• kchart.updateData(klines)

In V8 this code works fine.

PS: You've done some excellent work on the library. Very impressed.

@liihuu help please...

I used v9 to do similar operations, but no error occurred. I need more information.

Ok, just to wrap this up, v9.0a4 is working perfectly. Thanks @digitalml for the helpful pm.
