Cannot assign to read only property '6' of string XX #90

Hi,

I use FusionChart with Angular 10 for candlestick chart. I have a CSV file where each data (high, open, close ...) are extracted. I have an error in createDataTable() : ERROR Error: Uncaught (in promise): TypeError: Cannot assign to read only property '6' of string '2007-01-02' TypeError: Cannot assign to read only property '6' of string '2007-01-02'

I started with the example given in a tutorial but I struggle to pass data in a correct format I guess. At start, data are fetch from a server. See the tutorial : https://www.fusioncharts.com/fusiontime/examples/interactive-candlestick-chart?framework=angular4

app.component - Copie.txt Any idea ? Thank you :)

Hi,

Here is a working demo fetching data from an external CSV file - https://codesandbox.io/s/csv-angular-demo-wid6v

Hope this helps.

I got it to work on my project ! It seems the .map() method did the trick but I don't understand why. Can you explain me please @AyanBhadury ?

Thank again :)
