I've created a board game website where you are supposed to guess a word and then the points are displayed on a bar chart using chartjs. Currently, when hovering over a bar, it shows the amount of points by default. What I want to do is show both the amount of points and then also a list of what words that team have guessed correctly. So, in essence, can I change the hover text on a chartjs? And if so, how?
Thanks in advance!
I think you are referring to the tooltip which is showed when hovering the data elements.
You can change the data to show leveraging on tooltip callbacks, described in the doc: https://www.chartjs.org/docs/latest/configuration/tooltip.html#tooltip-callbacks
plugins: {
tooltip: {
callbacks: {
label: () => 'my text'
}
}
}

Im using Ag-grid to control my table, but i want in my group that stores a list of rows instead of having to make the row group expand in 2 clicks, i want to be on 1 click.
If i click on the icon arrow it works, but if i click on the title row it only opens on 2 clicks.
I already tried to find in the documentation any information about it, but cant find nothing.
Here is a example from the documentation.
https://ag-grid.com/javascript-grid-tree/index.php
example image:
We are now recommended not to use the onGroupExpandedOrCollapsed, so this should now be...
This will also update the icons and animate the rows, which onGroupExpandedOrCollapsed won't.
onRowClicked(params) {
params.node.setExpanded(!params.node.expanded);
}
This will toggle the expansion, use params.node.setExpanded(true) if you want the rows to just stay open.
You can listen to events on either a row or cell clicked, and expand nodes accordingly.
For example to expand a row based on a click you could do the following:
onRowClicked: (params) => {
// update the node to be expanded
params.node.expanded = true;
// tell the grid to redraw based on state of nodes expanded state
gridOptions.api.onGroupExpandedOrCollapsed(params.rowIndex)
}
This should be in the documentation - I'll update it to reflect this information.
In the column definition, you can use the onCellClicked(params) function to tell it to do something when the cell is clicked. I tried looking for an expand function, but I could only find expandAll() which I don't think you will want. So what I would do is just use jquery or simple DOM selection to click on the expand icon inside of that cell.
this one works
onRowClicked(params) {
params.context.setExpand.onExpandClicked(params.rowIndex, params.node.rowHeight);
}
I'm new to FusionCharts.
I have generated a pie chart with slice, my question is:
When I click on the slice in the pie chart, I need the label name of the slice.
How can I write the on click event and get the name of label?
I don't much about charts and such, I'm fine using Word for this. But in 2D Graphics I've learned you can use
...contains(shape)
...intersects(shape)
To see if shapes are inside eachother (to contain) or if they overlap eachother (to intersect).
When adding a mouseListener, you can use
e.getX() and e.getY()
to get the current X and Y position of mouse on screen.
So something like
for (pieChartPieces p: piece)
{
if (pieChartShape.contains(e.getX, e.getY))
{
//* Some kind of notifier for user pops up here.
}
}
Check out this fiddle here
It uses "dataplotClick" event to retrieve the label of the pie slice.
You have to use link attribute, as seen here.
"link": "JavaScript:populate('411');",
See the jsFiddle.
Don't forget to implement the populate() with the whatever you need to do.

I'm trying to configure the width for Alfresco.util.PopupManager.displayPrompt() but I don't see how to do it.
YUI Dialog has a width property, but the only config that I've managed to see, defaultDisplayPromptConfig object, doesn't seem to pay much attention to my messing with it.
Specifically, I tried setting Alfresco.util.PopupManager.defaultDisplayPromptConfig.width but it didn't work :)
I'm also trying to style up the panel I'm loading (create-site style injected panel), but it does not work for now.
Is there a way to configure the PopupManager Prompt object?
TIA
If you look at the source for Alfresco.util.PopupManager.displayPrompt() contained in alfresco.js then you'll see that the method creates an instance of YAHOO.widget.SimpleDialog, which does support a width property.
The problem is that displayPrompt() takes only specific configuration options which it passes through to the SimpleDialog, so adding an additional width parameter to your config will not have any effect, as you can see.
// Create the SimpleDialog that will display the text
var prompt = new YAHOO.widget.SimpleDialog("prompt",
{
close: c.close,
constraintoviewport: c.constraintoviewport,
draggable: c.draggable,
effect: c.effect,
modal: c.modal,
visible: c.visible,
zIndex: this.zIndex++
});
// Show the title if it exists
if (c.title)
{
prompt.setHeader($html(c.title));
}
// Show the prompt text
prompt.setBody(c.noEscape ? c.text : $html(c.text));
// Show the icon if it exists
if (c.icon)
{
prompt.cfg.setProperty("icon", c.icon);
}
// Add the buttons to the dialog
if (c.buttons)
{
prompt.cfg.queueProperty("buttons", c.buttons);
}
// Add the dialog to the dom, center it and show it.
prompt.render(parent);
prompt.center();
prompt.show();
I like the idea of enhancing the function to support a width property and possibly others, but in the meantime you are best off using SimpleDialog directly in your own code, modifying the above to add a width parameter.
In Leaflet, is it possible to define a marker or polyline with {clickable:false}, so that a click is passed through to whatever lies beneath - be it the map or a clickable geometry object?
At the moment I solve this problem by making the marker/polyline clickable and passing the event onwards myself. But this leads to the mouse cursor always showing as the hand symbol. Ideally, the mouse cursor should look like the normal pointer or the hand, depending on whether what is beneath the marker/polyline is clickable.
This may not be the answer you are looking for, but you can use featureGroups to have all of your clickable polylines come to the front so that the actions are surfaced.
var lg_noclick = new L.FeatureGroup().addTo(map);
var lg_click = new L.FeatureGroup().addTo(map);
// Add lines
lg_click.bringToFront();
updated fiddle
Also if you can afford to know your lines before hand, correct ordering of when you add the lines it will work as well.
I know this is not ideal but it suited my situation just fine, so it might be good for you as well.
This hides the icon and brings it back after a second using mouseenter and mouseleave events:
$('.leaflet-marker-icon').mouseenter(function() {
$(this).hide();
});
$('.leaflet-marker-icon').mouseleave(function() {
$(this).delay(1000).show(0);
});
We use Highcharts for our reports. On click of a chart, a new tab/window should open. I am able to achieve that by handling the click event in chart. But I am unable to make cursor as pointer.
Yes,
this is possible. See cursor.
Example (from that link).
Basically you set cursor option for the series:
plotOptions: {
series: {
cursor: 'pointer',
events: {
click: function() {
alert('You just clicked the graph');
}
}
}
}
If you want to make the whole chart clickable then you need to handle mouse hover/over. But then you may lose detail on where you are clicking (want to click series point but now you cant because you captured it on the "top" layer).
