Data label not rendered on sapui5 viz dual y-axis graph when line and column intersect

I have a requirement to show data labels of two graphs on the same axes.
Only when they intersect, one of the two labels won't show. This can be demonstrated below:
As you can see on the 2nd, 5th and 6th columns from the left with values 0%, 7% and 8% respectively
only the orange line values are shown but the blue column values are missing.
This is the final html of the graph after rendering:
So data-datapoint-id 142, 145 and 146 are missing from the html.
I tried using the plotArea.dataLabel.renderer function as a manipulation of what was proposed here but nothing changed, still not rendering.
Anyone encountered a similar problem? Is that a sapui5 issue or can it be fixed by manually inserting the labels into the HTML if so how?
Thanks,
Ori

Using SVG text and jQuery I managed to manually insert the labels into the top middle of the blue rectangle columns.
This is the result, not perfect but works:
and this is the code:
chart.setVizProperties({
plotArea: {
dataLabel: {
formatString: {'פחת כללי': FIORI_PERCENTAGE_FORMAT_2},
renderer: function (oLabel) {
// Create empty text node to be returned by the function such that the label won't be rendered automatically
var node = document.createElement("text");
if (oLabel.ctx.measureNames === "כמות פחת כללי") {
var kamutLabelIdx = oLabel.ctx._context_row_number;
// Use jQuery and SVG to manipulate the HTML
var kamutLabelQuery = '[data-id=\"' + kamutLabelIdx + '\"]';
var kamutColumn = $(kamutLabelQuery)[0];
// Create text element as child of the column
kamutColumn.innerHTML += "<text>" + oLabel.text + "</text>";
var labelNode = $(kamutLabelQuery += ' text');
// Set the label position to be at the middle of the column
const labelLength = 60;
const xPos = (labelLength + oLabel.dataPointWidth) / 2;
const yPos = oLabel.styles['font-size'];
labelNode.attr({
"textLength" : labelLength,
"x" : xPos,
"y" : yPos,
"font-size" : yPos
});
return node;
}
}
}
}
});
The oLabel parameter of the renderer function provides useful info about the data label to be created:
I still wonder if that's a bug with sapui5 vizframe and if there is a simpler way to do this.
Please let me know of your thoughts

Snap.svg and dynamic text

I'm trying to place text dynamically into an svg created by Snap, this is what I tried:
this.setContent(
`<svg id="${this.svgId}"></svg>`
);
var snap = Snap($(`#${this.svgId}`)[0]);
text = "asdfsdfsdsfd";
var rect = snap.paper.rect(0, 0, 50, text.length*3 + 4, 10);
snap.text(1.5,10, text);
console.log("rect", rect);
console.log("snap", snap);
rect.attr({
fill: "#FFFFFF",
fillOpacity: 0.6,
});
I get this:
I want the rectangle to be just a little bigger than the text, but there must be a better way to do it than to calculate the length and height of the text, and that's assuming the font size won't change.
This is the only result I found regarding text in the snap docs: http://snapsvg.io/docs/#Paper.text

You could try using getBBox() on the text element, and use that to figure the size of the rect. getBBox() wll give you the x,y,width,height,x2,y2 figures to help.
var text = s.text(0,0,'blah blah')
var bb = text.getBBox();
var rect = s.rect(bb.x, bb.y, bb.width, bb.height )
Adjusting with offsets for whatever padding etc that you want. You may also need to allow for stroke widths, as I don't think that's included.

d3 interaction between map symbol and a legend box

I have a map with circles with different colors based on different data values. The map comes with legend boxes each of which has a range of values. I am trying to figure out how to connect these two - when a map circle is clicked, I'd like to highlight the corresponding legend box. Right now, my click function highlightLegend() looks like this and it highlights all boxes when I click a circle:
circleColorMap.forEach(function(d, i){
legend.classed("legend-highlight", function(d) {
var colorVal = circleColorMap[i].value;
return colorVal >= id.roll_pm25;
});
});`
Here is the code. I know it has something to do with line 172, but I am not sure how to approach this.

You could do this entirely by matching colors:
//highlight a legend box that corresponds to a clicked map circle
function highlightLegend(id) {
var self = d3.select(this),
rects = d3.selectAll('.symbols>svg>rect');
// clear previous selection
rects.style({'stroke': 'none', 'stroke-width': '1px'});
// loop and hightlight matches
rects.each(function(){
var r = d3.select(this);
if (r.style('fill') === self.style('fill')){
r.style({'stroke': 'red', 'stroke-width': '2px'});
}
});
};
Updated code.

SAPui5 sap.viz.ui5.StackedColumn custom tooltip on data point

I am trying to implement a custom tooltip in a sap viz stacked column chart. This is the small popup window that appears when the mouse hovers a datapoint. My problem is how to detect the position of the data point so that the tooltip popup points to it. Currently it always points to the graph itself, not the datapoint inside the graph.
Here's what I have:
graph = new sap.viz.ui5.StackedColumn({
width: graphWidth,
height : graphHeight,
//.. more properties here
interaction: new sap.viz.ui5.types.controller.Interaction({
decorations: [{name: "showDetail", fn: showDetailHandler}, {name: "hideDetail", fn:hideDetailHandler}]
}),
and the showDetailHandler is currently like this. It is supposed to display a popup pointing to the data point.
var showDetailHandler = function(oEvent){
var data = oEvent.data;
var offset = '0 0';
var tp3 = new sap.ui.ux3.ToolPopup({
content : [ new sap.ui.commons.Button({
text : "button"
}) ],
});
offset = '0 0';
offset = oEvent.position.x + " " + oEvent.position.y;
tp3.setPosition( sap.ui.core.Popup.Dock.CenterBottom,
sap.ui.core.Popup.Dock.CenterTop,
$(oEvent.container),
offset,
"none");
if (tp3.isOpen()) {
tp3.close();
} else {
tp3.open(sap.ui.core.Popup.Dock.CenterBottom, sap.ui.core.Popup.Dock.CenterTop);
}
};
The docs around this are here:
https://sapui5.hana.ondemand.com/sdk/#docs/api/symbols/sap.ui.core.Popup.html#setPosition
https://sapui5.hana.ondemand.com/sdk/docs/api/symbols/sap.viz.ui5.types.controller.Interaction.html#getDecorations
My understanding is that the offset is an offset to the point calculated by the anchor point. Problem is, offset is completely ignored. Popup always appears at the top of the graph.
However, the normal tooltip appears in the correct place.
Any idea/example?
Thank you in advance.

Raphael.js centered text on path

What I have:
Text along a path made out of circle. It uses Raphael.js and a function called textOnPath (found here: Raphael JS Text Along path ):
var pathTest = r.path(getCircletoPath(286, 322, radius)).attr({stroke:"#b9b9b9"});
textOnPath(message, pathTest, fontSize, fontSpacing, kerning, kerning, point, textFill, fontNormal, fontFamily);
JSFiddle: http://jsfiddle.net/zorza/62hDH/1/
What I need:
The text to be centered on top of the circle.
My approach:
Try to calculate where the text should start depending on the arc size and text width. I tried to calculate the text width by creating it's invisible clone with text() function and get it's BBox width.
It doesn't quite work and the results vary depending on the web browser, font used and number of letters and spaces:
var length = r.text(100,400,message)
.attr({"font-size":fontSize,'opacity': 0, 'font-family': fontFamily})
.getBBox()
.width;
var point = (Math.PI*radius - length*fontSpacing)/2;
JSFiddle: http://jsfiddle.net/zorza/k8vBy/3/
Could anyone point me in the right direction?

The easiest way, IMHO, is to create additional helper path that is raised by half of text size. http://jsfiddle.net/p84VQ/
Also, I find it a bit more convenient to define a circle and then get points at specified angle:
var Circle = function(cx, cy, r) {
return function (a) {
return {
x: cx + r*Math.sin(Math.PI*-a/180),
y: cy - r*Math.cos(Math.PI*-a/180)
}
}
};
