saving amchart (Multiple SVG) as an image (jpg) using jquery/javascript

help you fix your problem If you could draw the chart on a canvas you could save that. Just saving a div and it's contents to an image is hard (I don't think it's even possible)...
Your question is related to this. It might help.

Set balloonText in Javascript Amchart

it fixes the issue You can assign user defined text in the hover balloon by defining a variable in your data array like below.
var d = {
    date: new Date(year_s,mon_s,date_s,hr_s,min_s,sec_s),
    customBullet: "round",
    balloonTextField: value+" points"
};
graph.balloonText = "[[balloonTextField]]";
chart.addGraph(graph);

Javascript / Amchart adjusting categoryFiled and color


Tag : javascript , By : leorick

it fixes the issue 1 - No. Coloring individual columns need to happen inside your data as it's using the fillColorsField property to find the color in each element in the dataProvider array. There isn't another way to do this. You can try modifying your JSON after the fact in JavaScript and add those colors in before assigning it to AmCharts' dataProvider.
2 - Set labelRotation in the category axis.
AmCharts.makeChart("chartdiv", {
  // ...
  categoryAxis: {
    labelRotation: 45,
    // ...
  },
  // ...
})

unable to overwrite the existing bar amchart with a new amchart based on dropdown selection

wish of those help You have a few problems with your code:
1) AmCharts.ready is simply a window.onload/$(document).ready assignment. It only runs the code inside AmCharts.ready on page load so calling it again will do nothing. Moving the AmCharts.makeChart call outside of AmCharts.ready will fix part of your problem.
var chart; //store the chart in a global that your populate function can refer to

function populateChartsBarFY(requestUriFY) {
  var chartDataResults2 = [];
  var AmountCollectedFYBar = 0;
  $.ajax({
    url: requestUriFY,
    type: "GET",
    async: false,
    headers: {
      "ACCEPT": "application/json;odata=verbose"
    },
    success: function(data) {
      var dataResults = data.d.results;
      var clr;
      for (i = 0; i < dataResults.length; i++) {
        var chartItems = dataResults[i];
        var dist = chartItems.District;
        var MineralCategory = chartItems.MineralCategory;
        AmountCollectedFYBar = parseFloat(chartItems.LastMonthCollection);
        if (MineralCategory == "Major") {
          clr = "#67B7DC";
        } else if (MineralCategory == "Minor") {
          clr = "#FDD302";
        } else if (MineralCategory == "Others") {
          clr = "#83B762";
        }
        var flag = false;
        for (var j = 0; j < chartDataResults2.length; j++) {
          if (chartDataResults2[j].MineralCategory == MineralCategory) {
            chartDataResults2[j].AmountCollected = (chartDataResults2[j].AmountCollected + AmountCollectedFYBar);
            chartDataResults2[j].balloonTextField = (dist + "," + MineralCategory + "," + (chartDataResults2[j].AmountCollected));
            flag = true;
          }
        }
        if (flag == false) {
          chartDataResults2.push({
            States: dist,
            MineralCategory: MineralCategory,
            AmountCollected: AmountCollectedFYBar,
            "color": clr,
            balloonTextField: dist + "," + MineralCategory + "," + AmountCollectedFYBar,
          });
        } 

      } // for

      if (!chart) { //if the chart variable isn't defined, do the first makeChart call and store the reference
        // SERIAL CHART
        chart = AmCharts.makeChart("chartdivdistFY", {
          type: "serial",
          dataProvider: chartDataResults2,
          categoryField: "MineralCategory",

Amchart - Export pie chart with background image?


Tag : development , By : AJacques
Date : March 29 2020, 07:55 AM
To fix the issue you can do I have to make pie charts with a background image. While clicking the export icon, it is showing the background image which is added to css. But when the file is downloaded, the image is missing. I see a 'fabric' option in exports. Is there any properties or methods to set the background image? , you can set the background image using before Capture function.
"export": {
      "enabled": true,
      "pageOrientation": "landscape",
      "beforeCapture": function() { 
           var cloneChart = this.setup.chart;
           cloneChart.backgroundImage="$image_url";
       }
}
