Unable to print chart on the fly visualization in mashup

Hi All,

unfortunatelly I'm back again!  I have developed a mashup creating all the objects on the fly by using APIs and/or hypercubes.

As you can see the mashup contains a charts section. The problem is when I try to print this section. I think the image below can better explain what I get from chrome browser printing tool:

Do not consider the position or the size of the DIVs these can be easily adjusted but pay attention to the charts inside those DIVs. They are oversized and I can't find the way to reduce the size. It is emabarassing!  I was able to prepare a css template for printing all the rest of the objects in the mashup but charts are out of my controll. 

Following you can find the code I used to create and style these object:

app.visualization.create(
  'linechart',
  [
    {
      "qDef": {
        "qGrouping": "N",
        "qFieldDefs": ["MonthName"],
        "qFieldLabels": ["2021"]
      },
      "qNullSuppression": true
    },
    {
      "qDef": {
        "qLabel": "Service Score",
        "qGrouping": "N",
        "qDef": "=expression",
        "qNumFormat": {
          "qType": "U",
          "qnDec": 1,
          "qUseThou": 0
        }
      }
    },
	{
      "qDef": {
        "qLabel": "Parts Score",
        "qGrouping": "N",
        "qDef": "=expression",
        "qNumFormat": {
          "qType": "U",
          "qnDec": 1,
          "qUseThou": 0
        }
      }
    },
	{
      "qDef": {
        "qLabel": "TK Score",
        "qGrouping": "N",
        "qDef": "=expression",        
		"qNumFormat": {
          "qType": "U",
          "qnDec": 1,
          "qUseThou": 0
        }
      }
    }	
  ],
  {
    "showTitles": false,
    "title": "Service Score Trend",
	"nullMode": "connect",
	"dataPoint": {
      "show": true,
      "showLabels": true
	},
	"measureAxis": {
		"show": "label",
		"dock": "near",
		"spacing": 0.5,
		"minMax": "max",
		"max":"1",
  	},
	"legend": {
      "show": true,
	  "showTitle": false,
	  "dock":"top"
    },
	"components": [
    {
      "key": "line",
      "style": {
        "dataPointSize": 6,
        "lineThickness": 3,
        "lineType": "solid",
        "lineCurve": "linear"
      }
    }
  ]
  }
  
).then(function(vis){
  vis.show("ServTrendPrint");
});

 

the object is then inserted in a DIV :

<div id="ServTrendPrint" class="chart"></div>

 

and this is the class definition inserted in the "@media print" section of my CSS file:

.subsection{
	width:95%;
	margin:auto;
	color: #dcddde;
	text-align: center;
	font-size: 1.3vw;
	font-weight: bold;
	text-shadow:none;
	box-shadow:none;
	border-radius:3px;
	border:1px solid cyan;
}
.chart{
	height:35vw;
	width: 100%;
	border-radius:3px;
	border:1px solid red;
}

where class "subsection" belongs to the DIV container of the chart object.

 

Can you please help me to understand where I failed?

thank you so much!!

You should try adding the  class="qvobject" to the div element

Hi Christopher,

 

thank you!

I've tried with your suggestion but I cannot get the correct resize of the canvas. However I found a trick to temporarly solve this issue using the "zoom" CSS property. I'll produce a more detailed reply to exaplain what I have done to solve it.
