No chart data found?

[mwicks23]

Dear HighCharts - I am having a problem using your system!

When I run HighCharts on the command line, my chart is generated perfectly; however, when I use HighCharts in server mode, I get an error:
"No chart data found. Please make sure you are using application/json or multipart/form-data headers, and that the chart data is in the options attribute if sending JSON."

This is the command that works correctly
"highcharts-export-server -infile ~/Desktop/highcharts_output_2.json -outfile ~/Desktop/output-file_2.png"

This command generates the above error:
"curl -H 'Expect:' -H 'Content-Type: application/json' -X POST -d @highcharts_output_2.json localhost:7801 -o output-file_2.png"

I'm running Highcharts in server mode like this:
"highcharts-export-server --enableServer 1 --host localhost --port 7801"

And this is the JSON I use in both situations:
{
"series": [
{
"name": "Ambiguous 1",
"data": [
{
"name": "SAMEA7495085-TCGTAGACACAGACTT",
"x": -7.84,
"y": -50.07
},
{
"name": "SAMEA7495085-TCTGGAACATGACATC",
"x": -5.35,
"y": -51.07
},
{
"name": "SAMEA7495085-TGACGGCTCTTTACGT",
"x": -8.69,
"y": -47.77
},
{
"name": "SAMEA7495085-TGCCCATAGCGAAGGG",
"x": -7.31,
"y": -49.11
},
{
"name": "SAMEA7495085-TGCGGGTTCGGCGCTA",
"x": -6.28,
"y": -49.53
},
{
"name": "SAMEA7495085-TGTGTTTCATGCTAGT",
"x": -15.95,
"y": -64.39
},
{
"name": "SAMEA7495085-TTAGGACTCAATCTCT",
"x": -8.81,
"y": -51.1
}
]
}
],
"xAxis": {
"visible": true
},
"yAxis": {
"visible": true
},
"title": {
"text": "E-MTAB-9684",
"align": "center",
"y": 20
},
"chart": {
"type": "scatter",
"height": 600,
"legend": {
"enabled": true
}
}
}

Obviously I'm doing something wrong - Can you tell me what please?

I tihnk I have to change the JSON so that the data is in the options field or something, but I can't find any documentation telling me how to do that?

Many thanks

Hello mwicks23!

Welcome to our forum and thanks for contacting us with your question!

Regarding JSON file, it should be formatted like that:

Code: Select all

{
    "chart": {
        "type": "bar",
        "backgroundColor": "red"
    },
    "title": {
        "text": "Fruit Consumption"
    },
    "xAxis": {
        "categories": ["Apples", "Bananas", "Oranges"]
    },
    "yAxis": {
        "title": {
            "text": "Fruit eaten"
        }
    },
    "series": [{
        "name": "Jane",
        "data": [1, 0, 4]
    }, {
        "name": "John",
        "data": [5, 7, 3]
    }]
}

You should also determine whether you are referring to the correct file path in the command, e.g::

Code: Select all

npx ./bin/cli.js --batch "./examples/chart.json=./examples/chart.png;"
