i have a same issue ... i didn't found a solution ...

i juste estimate how many value can i display in a page, and make chunk of my array ... regenerate the header manualy after each page break ...

andrelec1

In my report i have a table like this :

0_1566470057280_upload-394f916d-4a73-4f95-9f93-50a1d583f4fc

On this screen you can see i have a empty page for the 1px of the last row ...

How to avoid this ?

and if my table contains more rows ... how can i 'split' the table in two and regenerate the header on the other page ?

andrelec1

that is the issue ...

So i replace by :

<script src="https://www.amcharts.com/lib/4/core.js"></script>
        <script src="https://www.amcharts.com/lib/4/charts.js"></script>
        <script>
          {#asset ./lib/lodash.js @encoding=utf8}
        </script>

and it work ...

i try to import AmChart4 like lodash ( core.js and charts.js )
but i have error :/

if i use the external url that work ....
but i want use only local file if is possible

andrelec1

my header look like :

<head>
        <script>
            window.JSREPORT_READY_TO_START = false;
        </script>
        <style>
           {#asset ./css/KNACSS.css @encoding=utf8}
        </style>
        <style>
           {#asset ./css/content.css @encoding=utf8}
        </style>
        <script src="{#asset ./lib/lodash.js @encoding=link}"></script>
        <script src="{#asset ./lib/core.js @encoding=link}"></script>
        <script src="{#asset ./lib/charts.js @encoding=link}"></script>
        <script>{#asset ./script/colors.js @encoding=utf8}</script>
        <script>
            am4core.options.commercialLicense = true;
        </script>
        <script>
            const data = {{{ toJSON this}}};
        </script>
    </head>

caused by error (1) -> meta = {"workerTimeout":true,"logged":true}, stack = Error: Timeout Error: pdf generation not completed after 30000ms

I use the jsreport studio for design my pdf and it work ...
my pdf take around 5sec to be generated

but when i try to generate my pdf throught commande line with

jsreport render --template.name=report --data=test/dataJson.json --out=test/out.pdf

i didn't have any graph in it

i have this in the header

<script>
            window.JSREPORT_READY_TO_START = false;
</script>

and this juste before the end of the body

<script>
            am4core.ready(() => {
                setTimeout(() => {
                        window.JSREPORT_READY_TO_START = true;
                    }, 15000); 
                });
            });
        </script>

but that seem to not work ...
( i sure that not work , the command take less than 6 sec for generating the pdf , and this tel the pdf is ready after 15 second :/ )
(yess 15000 is realy big ... but its juste for testing, i choose a lower after )

So what i'm missing ?

andrelec1

seem to say at jsreport you page is ready before the pie is rendered
try with

setTimeout(
                function () {
                    window.JSREPORT_READY_TO_START = true;
                }, 3000); 
            });

Hooo, thank ...
i try to put the js code in the helpers.js ... that explain why am4core ins't defined ...

andrelec1

Hello,
I use 'handlebars' as engine and 'chrome-pdf' as recipe.

I try to add some graph from AmChart4 ...
( i'have allready set the "allowedModules": "*" in the config, i already use 'moment.js' ... )

So, npm i --save @amcharts/amcharts4
and in my script i add : const am4core = require('@amcharts/amcharts4/core');

but i have this error :

Error while executing templating engine. Unable to require module @amcharts/amcharts4/core. Unexpected token export
/home/andrelec1/Projects/rapportgenerator_v2/node_modules/@amcharts/amcharts4/core.js:8

^^^^^^

     |                 ^
  73 | 
  74 | const moment = require('moment');
  75 | moment.locale('fr');

its seem to be es6 related ... but how can i put babel in the project ?

I try to use cnd instead ...
So i try to add

<script src="http://www.amcharts.com/lib/4/core.js"></script>
<script src="http://www.amcharts.com/lib/4/charts.js"></script>

in the head of my template ...
but when i rendering the pdf i have a error that say am4core is not define ...
