Hi Ivan Cenov,

Thank you for using Wiki Gchart plugin, and I'm sorry for inconvenience.

As you mentioned, I also think that this is an issue of Redmine's PDF export.
I will investigate if this issue is not solved after solving the issue #3261.

Regards,
Murase

#9693 is the new related ticket.

Another problem is with ampersand inside a formula.

For example, the following formula doesn't work: {{latex(A=\begin{bmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{bmatrix})}}

#### #5 Updated by Ivan Cenovalmost 6 years ago

another latex
{{latex(x=a+b+c+d)}}

renders as
another latex x=a+b+c+d

And
before latex

{{latex(\frac{a}{b})}}
after latex

renders as
before latex

\frac{a}{b}
after latex

Hi Yoav.

I found that the bug of this plugin causes this issue.
I will release fixed version by the end of this month.

I opened an issue ticket on my GitHub page.

Murase

I've just released fixed version about 'ampersand error'.

I've also changed internal implementation, so this version shows raw string, such as '{{latex(a=b+c)}}', in PDF and email as is the case with other macros.

Please close this issue. It is too old. Google does not support these things this way.
