dodo,
As you are looking to remove margin from all four sides, you can add a dummy dataSeries with no dataPoints and secondary axisX and axisY. Code snippet shared below shows the same:
var chart = new CanvasJS.Chart("chartContainer",{
backgroundColor: "red",
axisX: {
valueFormatString: " ",
lineThickness: 0,
gridThickness: 0,
tickLength: 0,
margin: -10,
},
axisY: {
valueFormatString: " ",
lineThickness: 0,
gridThickness: 0,
tickLength: 0,
margin: -10
},
axisX2: {
valueFormatString: " ",
lineThickness: 0,
gridThickness: 0,
tickLength: 0,
margin: -10,
},
axisY2: {
valueFormatString: " ",
lineThickness: 0,
gridThickness: 0,
tickLength: 0,
margin: -10
},
data: [
{
type: "bar",
dataPoints: [
{ x: 10, y: 71 },
{ x: 20, y: 55},
{ x: 30, y: 50 },
{ x: 40, y: 65 },
{ x: 50, y: 95 },
{ x: 60, y: 68 },
{ x: 70, y: 28 },
{ x: 80, y: 34 },
{ x: 90, y: 14}
]
},
{
type: "bar",
axisXType: "secondary",
axisYType: "secondary",
dataPoints: []
}
]
});
chart.render();
Please take a look at this JSFiddle for a working example with sample code.
