In this fiddle what I'm after is giving all the 0s in the YAxis a grey colour without affecting the numbers that are bigger than 0. The issue here is that they are contained in the same SVG tag: <tspan>3000</tspan>. Is there a way I can target a particular text value inside a tag using css? i.e.
tspan[0]{
color: #808080;
}
Or is there a way I can do that using Highcharts' yAxis.labels.formatter ?
This is totally hacky, but I got it to work. Under yaxis:
labels: {
formatter: function () {
var label = this.axis.defaultLabelFormatter.call(this);
label = label.replace(/(0+$)/,'<span style="color: #ccc;">$1</span>');
return label;
}
},

I have created a HighChart in a Ag data grid cell. On hovering over the Line chart, I need to display a tooltip with few details. I am able to show the tooltip within the cell, but as the tooltip is displayed within the cell, the content gets hidden in the cell. I need to display the tooltip in such a way that it can overlap and display the tooltip over another cell.
I tried setting the z-index to 99999 & position as relative/absolute of highchart tooltip. But it does not reflect.
Tried to override the css class .highcharts-tooltip by adding z index
Please can some css expert help me identify the issue?
There is no need to modify the CSS of the highchart tooltip.I followed the properties used in the below URL & it worked for me:
https://www.highcharts.com/demo/sparkline
I had missed out adding below chart options:
tooltip: {
outside: true,
}
plotOptions: {
series: {
animation: false,
lineWidth: 1,
shadow: false,
states: {
hover: {
lineWidth: 1
}
},
marker: {
radius: 1,
states: {
hover: {
radius: 2
}
}
},
fillOpacity: 0.25
}
}
I need to show the label values inside the Highcharts bar chart. It can be implemented using dataLabels.Formatter function.
But when the bar is in consist-able size the labels are shown inside the bar and it is looking good. In some cases, the bar is very small in size comparing to the label.
Please see the code pen here, https://codepen.io/JGSpark/pen/YzzBydv?editors=1010
The last bar is very small and 40 is showing outside. As the color: 'white' is commonly used for all the labels it is showing in white though it is in outside.
How can I change the color of the label if it is showing out?
In this example, I need to change the color of label 40 to black. Any suggestions?
You need to add custom formatter which will check the size of yAxis value and will change the color of label accordingly:
formatter: function() {
var max = this.series.yAxis.max,
color = this.y / max < 0.05 ? 'black' : 'white'; // 5% width
return '<p style="color: ' + color + '">' + this.y + ' M</p>';
},
If your chart is not a dynamically created you can set the dataLabels.color for the particular point.
{
y: 40,
dataLabels: {
color: 'black'
}
}

EDIT
Another solution which I can suggest is to add a functionality inside the chart.events.load which will filter if dataLabels is aligned to left or right and set wanted color - it will work if more labels will be outside the column bar.
events: {
load() {
let chart = this,
series = chart.series;
series[0].points.forEach(p => {
if (p.dataLabel.alignOptions.align === 'left') {
p.dataLabel.css({
color: 'black'
})
}
})
}
}

I have 2 nested <div>s, both with tooltip().
When I hover over the
inner <div>, the outer <div> also shows it's tooltip.
I tried to work around this by setting the inner <div>'s title
to an empty string on :hover.
$(inner).hover({
$(outer).attr('title','');
},{
$(outer).attr('title','original title');
});
I created a codepen examplenote: I changed title to 'red' so you can see that the title did indeed change.
Why is it that changing the title doesn't change tooltip's content?
How do we change the Bootstrap Tooltip's content? (this should be a stackoverflow question of it's own)
Answering #1:
By inspecting the elements and watching it change with your JS code, i noticed a attribute on the divs called data-original-title which still holds "blue" when you enter green (this is what the tooltip element reads and displays). By changing your script to
$('#a').attr({"data-original-title": "red"});
the blue becomes red. Does this answer your question?
Use .tooltip('hide') and .tooltip('show')
this was answered in part by #BuddhistBeast, thanks!
$("#b").on('mouseover', function(){
$('#a').tooltip('hide');
}).on('mouseleave', function(){
$('#a').tooltip('show');
});
$('[data-toggle="tooltip"]').tooltip({
animated : 'true',
placement : 'bottom',
container: 'body'});
You can check whether you are currently hovering inside of the inner block
jQuery:
$(document).ready(function(){
var bIsShown = true;
$("#b").on('mouseenter', function(){
bIsShown = true;
}).on('mouseleave', function() {
bIsShown = false;
})
$("#a").on('mousemove', function(){
if(bIsShown) {
$(this).data("bs.tooltip").$tip.removeClass("in");
}
else {
$(this).data("bs.tooltip").$tip.addClass("in");
}
})
$('[data-toggle="tooltip"]').tooltip({
animated : 'fade',
placement : 'bottom',
container: 'body'});
});

I'm working with nvd3 and I'm not much hands-on with its styling (css properties) to customize it. I have a line chart with two data lines on it.
The code for drawing the lines is following:
nv.addGraph(function() {
chart = nv.models.lineChart();
chart.margin({
left : 100,
bottom : 100
}).useInteractiveGuideline(true).showLegend(true).duration(250);
chart.xAxis.axisLabel("Date").tickFormat(function(d) {
var date = new Date(d);
return d3.time.format("%b-%e")(date);
});
chart.yAxis.axisLabel('').tickFormat(d3.format(',.2f'));
chart.showXAxis(true);
d3.select('#startupRiskLineChart').datum(
prepareDataObj(val1_y, val1_x, val2_y, val1_x))
.transition().call(chart);
;
nv.utils.windowResize(chart.update);
chart.dispatch.on('stateChange', function(e) {
nv.log('New State:', JSON.stringify(e));
});
return chart;
});
Is there any way to fill the area under data line with a lighter color?
Any help would be highy apperiated.
To get a line chart with a filled area in a specific color:
Add area: true to the data series, as in this example.
Add this CSS: .nv-area { fill: red }
The opacity of the area is set to 0.5, so filling it with red will actually make it pink:
chart.color(["red","yellow","blue"]);
'#00FFFF','#0FF','cyan' all are valid ways to set colors
Another way is set it in data itself
[{
values:[{x:1,y:1},{x:2,y:4},{x:3,y:9},{x:4,y:16}],
key: 'not a Sine Wave',
color: '#ff7f0e' //color - optional: choose your own line color.
}]
duplicate question i guess
Add
classed: "my-custom-approx-line"
to config of specific line and add styling:
&.nv-area {
fill-opacity: 0.2;
}
As of commit #becd772
Use .nv-group{ fill-opacity: 1.0 !important; } to fill the area with the same color as the line
I'd like an option with the TinyMCE color picker to choose transparent as the color so a character (a "bullet") will still be there and take up space but will not be visible if it's color is transparent.
There's an "X" box option that says "No color" but this seems to make the color black, not transparent.
Does anyone know how to add a transparent color option to this color picker, or even make the "X" box implement transparent instead of black?
Thanks for any ideas.
I believe I was able to do that, I did some quick tests and it appears to be working fine.
I got the latest version of TinyMCE (4.1.10_dev) to access the textcolor plugin's non minified javascript there's this instruction:
if (value == 'transparent') {
resetColor();
} else {
selectColor(value);
}
What happens here? When you choose a color it runs the selectColor, which wraps the selected text in a span with the selected color. However, when you select the no color it removes this color span (that's why it goes back to black which is the default color) instead of setting it to transparent.
So if you do this:
//if (value == 'transparent') {
// resetColor();
//} else {
selectColor(value);
//}
Instead of removing the span it will change it to 'transparent' instead.
One important thing is that tinyMCE gets the plugin scripts automatically, so it only works with the minified versions, so after you do these changes you'll have to minify the script to the plugin.min.js and put it on the textcolro plugin's folder overwriting the one there.
I hope it helps.
The × button in the colorpicker removes any custom colours, it does not add a zero-opacity colour.
As you can see when looking at the source code or trying the full example there is no support for rgba() or opacity in the included colorpicker plugin. Only rgb() and hex unfortunately.
You may need to create your own small plugin to add the ability. There are a number of alternatives, for example:
Create a CSS class which you can add to elements in the editor. Then do your colour magic in your own CSS file.
Create a new button in the toolbar which makes the element transparent.
I would personally go with option two, something like this:
tinymce.init({
selector: 'textarea',
plugins: 'nocolour',
toolbar: 'nocolour',
external_plugins: {
"nocolour": "url_to_your/nocolour.js"
}
});
And nocolour.js:
tinymce.PluginManager.add('nocolour', function(editor, url) {
// Add a button that opens a window
editor.addButton('nocolour', {
text: 'Remove Colour',
icon: false,
onclick: function() {
editor.undoManager.transact(function() {
editor.focus();
// Here is where you add code to remove the colour
editor.nodeChanged();
});
}
});
});
Rafael's solution worked for me. I just wanted to document it a bit more and show what it looks like for TinyMCE 4.1.7.
When you click the "X" in the textcolor grid the "value" variable gets "transparent," rather than a hex value from the colorMap.
The relevant code in the textcolor plugin is:
value = e.target.getAttribute('data-mce-color'); // the hex color from the colorMap square that was clicked. "transparent" if X was clicked
if (value) {
if (this.lastId) {
document.getElementById(this.lastId).setAttribute('aria-selected', false);
}
e.target.setAttribute('aria-selected', true);
this.lastId = e.target.id;
// if (value == 'transparent') { // occurs if you select the "X" square
// removeFormat(buttonCtrl.settings.format);
// buttonCtrl.hidePanel();
// return;
// }
selectColor(value);
The five lines I've commented out remove formatting for the selected text, leaving it black, which doesn't seem useful. If you wanted the text black you could select the black square in the colorMap. Falling through to selectColor(value) with value = "transparent" sets transparent as the color.
