在amCharts中更改甘特图，以便列值是轴值，旧轴值是新列值？

Question

I have a Gantt chart using amCharts v3 in PHP, and we would like to swap the column values with the X-axis values. For example, we have an incident Gantt chart which have X-axis values of the locations of incidents and the columns are the staff members of a school that were attached to that location, with how many incidents they were attached to.

I have tried looking for the data that is pulled to create the chart and how they are used, but cannot see how to swap it around. Unfortunately I cannot display code as it is my company's and not mine.

First of all I would recommend to upgrade to amcharts4 , because it is much more flexible and has even new chart types. You can migrate easily, beginning with just one chart. You can use amcharts3 and amcharts4 in parallel ( Migration Guide ).

With amcharts4 it is possible to swap the xAxis and the yAxis .

I used the gantt chart from the amcharts demos and updatet it in a code pen .

If you want to stay with amcharts3 it is also possible to swap xAxis and yAxis . You just have to invert the rotate attribute in the config json:

var chart = AmCharts.makeChart( "chartdiv", {
    "type": "gantt",
    // your config ...
    "rotate": false,
    // more config ...
} );

I created another code pen with the full amcharts3 example adapted from the demo chart .
