I am using HighCharts in my ASP.Net MVC application using JQuery.
I have managed to show a tooltip with crosshair vertical bar on mouse move. However, I do not want to hide this toolop + bar even if user moves the mouse out of chart. Is there any option available in Highcharts to achieve this?
I searched forums but could not find any working example. One of those solutions is related to cloning tooltip on click event.
You can wrap the Highcharts.Tooltip.prototype.hide by an empty (no-op) function as follows
(function (H) {
H.wrap(H.Tooltip.prototype, 'hide', function (defaultCallback) {
/*

});
}(Highcharts));
Highcharts/Highstock tooltip always visible # JsFiddle
For the minimalists,
(function (H) {
H.wrap(H.Tooltip.prototype, 'hide', function () {});
}(Highcharts));
does the job too ;)

Is it possible to click on the chart and drag around like tradingview panning ?
Right now its creating rectangle only.
const chart = lightningChart().ChartXY()
// Method for adding OHLCSeries takes one argument: seriesConstructor.
const ohlcSeries = chart.addOHLCSeries(
// Specify type of figure used
{ seriesConstructor: OHLCFigures.Candlestick }
)
You can pan the chart with right click of the mouse. Right now it's not possible to switch the panning of the chart to left click but we are planning to implement a solution to remap the mouse/touch interactions in future.
You can also remove an axis from the panning interaction by calling axis.setChartInteractionPanByDrag(false).
EDIT:
With the new v3.0.0 release, ChartXY mouse interaction buttons can now be explicitly configured. For example, changing panning to left mouse button, and rectangle zoom/fit to right mouse button:
const lcjs = lightningChart({
overrideInteractionMouseButtons: {
chartXYPanMouseButton: 0,
chartXYRectangleZoomFitMouseButton: 2,
},
})
const chart = lcjs.ChartXY()
My canvasjs chart floats right then on inspection gets back to its original position. What might be the issue?
I have 2 dynamic canvasjs charts in my site inside to tab-body. The 1st chart is displaying fine but when I click on the 2nd tab the chart inside it floats left and then after inspection gets to its original position. All of the data is fine just want to know the js or css issue.
i did the php like this data are all fine and are working good.
<div class="charcon_n" id="chartContainer_n<?php echo $i; ?>" style="height: 350px; width: 100%;" data-point='<?php echo json_encode($data_n, JSON_NUMERIC_CHECK); ?>'></div>
Whenever a tab is switched, the render method of each of the chart in the activated tab should be called so that chart can take the actual dimensions of its container.
$("#tabs").tabs({
create: function (event, ui) {
//Render Charts after tabs have been created.
$("#chartContainer1").CanvasJSChart(options1);
$("#chartContainer2").CanvasJSChart(options2);
},
activate: function (event, ui) {
//Updates the chart to its container size if it has changed.
ui.newPanel.children().first().CanvasJSChart().render();
}
});
Please take a look at jQuery gallery example.
I'm trying to implement a TinyMCE button that will apply the style of the selection to the entire box. I'm having trouble, though, reading the style of the selection when the selection is buried in a span in a span in a paragraph. Let's consider 'color' for example. Below I have a box with some text and I've selected "here" in the paragraph and made it red.
The HTML for the paragraph is now:
The code behind my button to apply the style of the selection to the box is
var selected_color = $(ed.selection.getNode()).css('color');
console.log("color pulled is ", selected_color);
$(ed.bodyElement).css('color', selected_color);
It doesn't work because the color pulled is black, not red, so the third line just re-applies the black that's already there. (If I replace selected_color in the third line with 'blue' everything goes blue.) So the problem is pulling the color of the current selection.
Does anyone know how I can do this reliably, no matter how buried the selection is?
Thanks for any help.
I also noticed somewhat a strange behavior up and there, with selections of nested span's and div's, but honestly i'm not able to recognize if this is a bug of TinyMCE, a browser issue or a combination of both (most probably).
So, waiting for some more information from you (maybe also your plugin code) in the meanwhile i realized two proposal to achieve what you want: the first plugin behaves like the format painter in word, the second is simply applying the current detected foreground color to the whole paragraph.
As you move throug the editor with the keyboard or mouse, you will see the current detected foreground color highlighted and applied as background to the second plugin button.
Key point here are two functions to get the styles back from the cursor position:
function findStyle(el, attr) {
var styles, style, color;
try {
styles = $(el).attr('style');
if(typeof styles !== typeof undefined && styles !== false) {
styles.split(";").forEach(function(e) {
style = e.split(":");
if($.trim(style[0]) === attr) {
color = $(el).css(attr);
}
});
}
} catch (err) {}
return color;
}
function findForeColor(node) {
var $el = $(node), color;
while ($el.prop("tagName").toUpperCase() != "BODY") {
color = findStyle($el, "color");
if (color) break;
$el = $el.parent();
}
return color;
}
The try...catch block is needed to avoid some occasional errors when a selected text is restyled. If you look at the TinyMCE sorce code you will notice a plenty of timing events, this is a unavoidable and common practice when dealing with styles and css, even more with user interaction. There was a great job done by the authors of TinyMCE to make the editor cross-browser.
You can try out the first plugin in the Fiddle below. The second plugin is simpler as the first one. lastForeColor is determined in ed.on('NodeChange'), so the code in button click is very easy.
tinymce.PluginManager.add('example2', function(ed, url) {
// Add a button that opens a window
ed.addButton('example2', {
text: '',
icon: "apply-forecolor",
onclick: function() {
if(lastForeColor) {
var applyColor = lastForeColor;
ed.execCommand('SelectAll');
ed.fire('SelectionChange');
ed.execCommand('forecolor', false, applyColor);
ed.selection.collapse(false);
ed.fire('SelectionChange');
}
return false;
}
});
});
Moreover: i think there is a potential issue with your piece of code here:
$(ed.bodyElement).css('color', selected_color);
i guess the style should be applied in a different way, so in my example i'm using standard TinyMCE commands to apply the foreground color to all, as i wasn't able to exactly convert your screenshot to code. Please share your thoughts in a comment.

deblocker,
Amazing work! Thank you!
Your jsfiddle did the trick. I replaced the HTML with what was in my example and changed the selector in tinymce.init from a textarea to a div and it pulls the color out perfectly from my example. The modified jsfiddle is at https://jsfiddle.net/79r3vkyq/3/ . I'll be studying and learning from your code for a long time.
Regarding your question about
$(ed.bodyElement).css('color', selected_color);
the divs I attach tinymce to all have ids and the one the editor is currently attached to is reported in ed.bodyElement. I haven't had any trouble using this but I have no problem using your
ed.execCommand('SelectAll');
ed.fire('SelectionChange');
ed.execCommand('forecolor', false, applyColor);
Thanks again! Great job!
I have a nice chart in highcharts that the user can zoom into. I really don't like the built-in ZOOM RESET button, and would like to add my own custom zoom reset button into a nav bar already present.
So my questions are:
1. Is there a way to hide the default highcharts ZOOM RESET button?
2. Is there a method/function I can call to perform the ZOOM RESET? (I can call that from my own button click)
You can pass resetZoomButton as display: none and call zoomOut.
chart: {
resetZoomButton: {
theme: {
display: 'none'
}
}
}
$('#resetZoom').click(function() {
chart.zoomOut();
});
<input type="button" value="reset zoom" id="resetZoom"/>
Demo
Just get the chart and call zoomout:
chart = $("#your-chart").highcharts();
chart.zoomOut();
Seeking a solution to my problem...
I partially found an answer from another thread on here, using this script
$(function () {
$(".myclass").hover(function ()
{}, function ()
{
$(".myclass>li").fadeTo(200, 1)
});
$(".myclass>li").hoverIntent(function ()
{
$(this).attr("id", "current");
$(this).siblings().fadeTo(200, .6);
$(this).fadeTo(300, 1)
}, function ()
{
$(".myclass>li").removeAttr("id");
$(this).fadeTo(200, 1)
})})
When an item in the list is hovered, the script fades all other items out. Original demo is here http://jsbin.com/usobe
This works OK on my site, though the list ( a grid of thumbnails) is part of a bigger slider script, which loads "previews" via ajax. When a list item is clicked a hidden section expands on the page, and the slider script assigns the list item a class "active".
When the hidden section is open I would like the activated thumbnail to remain at 1 opacity, while the rest are faded to .6, exactly as it is with the hover effect using the script above. What I am trying to achieve becomes obvious when you click a thumbnail to activate the ajax script. Is it possible to use the active class to make this happen i.e. if class is not active set to .6 opacity?
Thanks in advance
----EDIT
Thanks everyone for suggestions - I am not having much luck so far! Using the code above, would it be possible to modify it so that when a list item is clicked it holds the specified levels of opacity? That would do nicely, I think. Then I could use onclick I guess to fade all items back to full opacity when the hidden div is closed.
I'm trying to guess how your code work, for what I understand you should do something like this:
// this is the selector that gets the click on the thumbnail
$('li.item').click(function() {
// fade all the thumbnails to op 1.0
$('#li.item').css('opacity', '.6');
// let the active thumbnail to 1.0
$(this).css('opacity', 1);
//show your hidden div
});
Then, when you close the hidden div:
$('div#hiddenDiv').onClose(function()
// about to close
$(this).fadeTo('fast', 1);
});
You could use an on click targeting the zetaThumbs li elements, set the current target to 1 and its siblings to .6
$('.zetaThumbs li').click(function(){
$(this).css({'opacity':1}).siblings().css({'opacity':.6});
})
