Angular version 16; D3 version 7.9.0; D3-org-chart version 3.1.1… I created a chart of organization. But I would want to provide the organizational chart a zoom-in and zoom-out function.
I added the code for zoom-in and zoom-out feature but when zoom-in or out the chart disappeared.
I don’t know how to set the zoom-in ,zoom-out limitations for organizational chart.
HTML code
<div id="orgchart" class="chart-container"></div>
SCSS code
#orgchart {
.node .label {
fill: green !important;
}
.node .title {
fill: red !important;
}
.node rect {
fill: lightblue !important;
}
svg {
background-color: rgb(213, 219, 220);
}
::ng-deep.node-button-div {
width: 134% !important;
}
// ::ng-deep svg.svg-chart-container {
// height: 200vh !important;
// }
::ng-deep svg.svg-chart-container {
height: auto !important;
width: auto !important;
}
}
