I am trying to always enable all the tooltips for Bubble chart using react-charjs-2 plugin
I tried various approaches but none of them work with the latest version of the plugin
Would appreciate some advice, Thank you! :)
I tried the all possible approaches, including the following ones, but was unable to achieve the results
Tried the following:
Chart JS: Always show tooltips in a multi dataset line chart
By default it is not possible to show all the tooltips at once, if you really want it you will need to use the external (html) tooltip.
The easyer way is to use the datalabels plugin: https://chartjs-plugin-datalabels.netlify.app/samples/charts/bubble.html

I have a chartjs doughnut chart which is displaying fine, but when printed as a pdf, the tooltips don't show.
I've tried targeting .tooltip class within an #media print{} block, but this didn't work. I tried some implementation with custom property in the tooltip options but nothing I've tried worked at all.
Does anyone have a solution, where the tooltips will either always persist, or can be persisted when printing the HTML page to a pdf?
Thanks,
I think you might be better off using the data labels plugin, will give your chart a cleaner look instead of having a tooltip active for each element: https://chartjs-plugin-datalabels.netlify.app/samples/charts/doughnut.html
I am looking charts like below in Chart.js library
http://plottablejs.org/examples/synchronized/
https://www.highcharts.com/demo/synchronized-charts
Does anyone know how can I do it?
There appears to be a plugin for Chart.js called "chartjs-plugin-crosshair". Look at the "Linked Charts" example here https://chartjs-plugin-crosshair.netlify.app/samples/
I m working on charts using the chart.js library. I want to show image gallery like a carousel on click of any segment of pie/doughnut chart. I'm not able to find the proper solution. Please suggest some solution
If I understand correctly what you are trying is to trigger an event after user clicks on chart segment. chart.js has this prototype method getElementAtEvent(); See the documentation.
It seems as a good place to start - you could create some function to open image gallery and call it there.
And the gallery/slider implementation is a separate issue, but if you are using some of the popular ui libraries some of them have a solution for that already. Bootstrap, for example has carousel, and JQuery has many plugins for that purpose. Here are some examples. Hope this helps...
i'm trying to create some charts with google charts api. I need a bar chart with values placed directly on the chart (not on the tooltip which is set by default). I know that it was possible in Image Charts (which are now deprecated). Is there any way to achive a similar result in Google Charts? I will be grateful for any help or advice...
Here are some examples of what i want to achieve:
No, there isn't. See the answer in this question.
Quote follows:
This feature is not currently supported. The only way to implement it is to write some fancy javascript to create it.
I am no pro at working with SVG with javascript, and won't pretend to be. I'll let you know what I found out with Firebug, and share that.
Using this chart I inspected the SVG element that's created. It has 5 different <g> (I'm assuming group) elements.
g[1] contains information on the title.
g[2] contains the legend
g[3] contains the chart information (sub-groups with the chart
area, gridlines, series, axis label values, etc.) -- when a point is
selected, this shows the circle/double-circle for that point too
g[4] contains axis titles
g[5] contains the tooltips in two separate groups, but only on
mouseover
Here is the function in the code that gets triggered when you mouseover a point:
Y.Ov=function(a,b,c){a=new kv(a);var d=this.Mf.pk(Wj);b=b[zc](sd);d[w](this.Mf[sb](b[0]));for(var e=1;e<b[L];++e)d[w](this.Mf.pk(ti)),d[w](this.Mf[sb](b[e]));Qt(d,c);a.t()[w](d);a.Zz(100);a.Yz(100);this.on[y](a);return a};Y.appendChild=function(a,b){if(b){var c;if(b[Bc]==Sv){if(!b.Th())return;c=b.t()}else c=b;a.t()[w](c)}};Y.replaceChild=function(a,b,c){a.t().replaceChild(b,c);Cu(c)};Y.Fg=function(a){a.Th()&&this.xs(a.t())};Y.xs=function(a){this.Mf.Fg(a)};Y.ds=function(a){this.Mf.removeNode(a);Cu(a)};
This probably doesn't help you. I can't find any easy way to create a workaround for this (oh-so-needed) feature. Sorry there's no solution yet!
I'm using the Google Charts API to include various graphs on a webapp I'm working on. I'm using the javascript chart tools (not the image chart tools), and am wondering if it's possible to use a transparent background on a chart (e.g. line graph, pie chart, etc.)?
In the Configuration Options of the chart, specify
backgroundColor: { fill:'transparent' }
This worked for me in Chrome and Firefox.
It took me some time to find out. The doc page says you can only put in HTML color strings and I assumed 'transparent' was not one of them.
Setting a transparent background for Google Charts:
// Set chart options
var options = {'title':'Chart Title',
'width':600,
'height':300,
'backgroundColor': 'transparent',
'is3D':true
};
JSFIDDLE DEMO
backgroundColor: "00000000" worked for me.
If nothing works for you try locating the background rectangle at the end of your drawChart() function and add the fill-opacity attribute.
fill-opacity="0.0"
Example:
$('#mychart').find('svg rect:eq( 1 )').attr('fill-opacity','0.0');
Use the eq:() selector to select the rectangle you want to be transparent.
On the left of the cart there is a dropdown arrow - click that, and go to "cop chart".
When you paste the chart, you can still choose to link it, and it will paste with the background transparent.
