   Hi @Wongboo

   I would really appreciate a full code example, but i managed latex output to work in principle.

   The problem is MathJax (the tex rendering engine used in plotly tex examples) not being referenced in our HTML scaffold. For a workaround until this is properly implemented, add these script tags to the html:

   <script type="text/x-mathjax-config;executed=true">MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']], processEscapes: true}});</script>
   <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS-MML_HTMLorMML%2CSafe.js&ver=4.1"></script>

   Additionally, as tex uses a lot of \ characters, your tex strings should be escaped using @:

   [
       Chart.Line([(1.,2.)],@"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$")
       Chart.Line([(1.,2.)],@"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$")
   ]
   |> Chart.Combine
   |> Chart.Show

   Which will then look like this:

   

   From our side it is most likely the best to set this on the Config level of GenericChart, providing a Chart.withMathTex function indicating that the mathtex script should be contained in the html scaffold.

   @kMutagene
   I kind of understand, so this generally means that until the official support is established, We have to change the source code of Plotly.NET or manually add

   <script type="text/x-mathjax-config;executed=true">MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']], processEscapes: true}});</script>
   <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS-MML_HTMLorMML%2CSafe.js&ver=4.1"></script>
   

   to the chart which might be too complicated since no API in GenericChart supports directly adding these script tags. Am I right?

   or manually add [script tags]
   to the chart which might be too complicated since no API in GenericChart supports directly adding these script tags. Am I right?

   I can think of two workarounds that might work for you in the meantime:

   • The output of Chart.Show is a html text file like any other, so you can open the files programmatically and add those lines.

   • The GenericChart.toChartHTML returns the contents of that file as a string, so you can add these lines there and then write the content to a file like this:

      [
      Chart.Line([(1.,2.)],@"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$")
      Chart.Line([(1.,2.)],@"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$")
      ]
      |> Chart.Combine
      |> Chart.toChartHTML
      |> `add the missing lines`
      |> `write to a .html file`

   So temporarily solution is to change the HTML directly through adding these lines.
   In the long term, wait for the API change in MathJAX.
   Thanks for your help!

   Exactly, i don't imagine this feature taking too long to implement though

    @Wongboo Watch out for the next release, you will be able to use Chart.WithMathTex:

    [
        Chart.Line([(1.,2.)],@"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$")
        Chart.Line([(1.,2.)],@"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$")
    ]
    |> Chart.Combine
    |> Chart.withTitle @"$\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}$"
    |> Chart.WithMathTex(true)
