Convert d3 svg coordinates to canvas coordinates



I have some d3 svg elements in which I pass as attribute a list of coordinates x,y and I plot them on a svg map. Like the example below:


var svg = iniMarker().append("g")
.attr("data-lineData", JSON.stringify(lineData))



Now I need to represent each of these points taken from this coordinates list on a canvas map. And in that case the problem is that the svg coordinates of the list don't match with the canvas coordinate.



In fact if I try to generate some canvas coordinate points by using the function below:


document.getElementById("canv").onclick = function (e)
var localX = e.clientX - e.target.offsetLeft;
var localY = e.clientY - e.target.offsetTop;



Then the coordinates at the onclick event are pretty much different from the svg coordinates.
I need to find a way to convert the list of svg coordinates that I have in order to match or be more similar as possibile to the canvas coordinates system.



I'm open to suggestions.

I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Clash Royale CLAN TAG #URR8PPP Store custom data using WC_Cart add_to_cart() method in Woocommerce 3 I am creating a membership site and totally created static pages for each Membership plans (have only 3 plans). However, I have added products for each plan and when I hit SELECT PLAN button I redirect to some custom form where I ask users range of info we are going to use to fulfil the plan (same as sneakertub.com). I have written code into the PHP page which will handle SUBMIT action of the form. This PHP file, infopage.php , will process POST data I sent via POST call and stores these all data into WC session. infopage.php $customer_name = $_POST["customer_name"]; $customer_email = $_POST["customer_email"]; $customer_sex = $_POST["customer_sex"]; $customer_age = $_POST["customer_age"]; $product_id = $_POST["product_id"]; global $wp_session; $data = array( 'customer_name' => $customer_name, 'customer_email' =...
