Problem with CHART

I tried to put in a page one of the example charts

{up chart=Column
| title=Taux d'utilisation des navigateurs Internet en 2019| height=400
| area=2,15,98,75}
Navigateur,2019,##color##,##label##
Chrome,57.4,green,Chrome
Safari,13.5,indigo,Safari
IE et Edge,6.8,#369,IE
Firefox,6.8,#FF8C00,Firefox
Opera,2.4,red,Opera
{/up chart}

but I get this error:
Data column(s) for axis #0 cannot be of type string×

Some one can help, please? Thank you

hi,
Try putting the lines one by one to find the one that generates the error

{up chart=Column | title=test} 0,0 {/up chart}
{up chart=Column | title=test} ciao,0 {/up chart}
{up chart=Column | title=test} 0,ciao {/up chart}

all the three examples gives the same error as above

With this shortcode: I get this:

Hard for me to fix a problem that I can't reproduce

Found the problem. To make it work, I have to put it between <pre></pre> in source view

It is not normal. Which editor do you use ?
