https://community.qlik.com/t5/App-Development/How-can-I-cycle-through-my-data-points-to-see-which-ones-are/m-p/2088006#M89183 <P>Hello,</P> <P>I have a lasso example on a picasso.js scatter plot at this JSFiddle:&nbsp;<A href="https://jsfiddle.net/3sbvwpxa/" target="_blank">https://jsfiddle.net/3sbvwpxa/</A>. You can try it out by drawing a lasso around any set of points you want.</P> <P>Once the lasso is complete (user releases mouse button), I need to be go through all the data points and figure out which ones are in the lasso. This means I need to:</P> <P>1) iterate through each data point.</P> <P>2) run each point through a function/algorithm that figures out if its inside the lasso or not.</P> <P>I need help with both of these. How do I get access to my data points? And does anyone know a good algorithm for determining if points are within a lasso region?</P> <P>Thanks!</P> Mon, 26 Jun 2023 22:23:06 GMT gibran-shah 2023-06-26T22:23:06Z https://community.qlik.com/t5/App-Development/How-can-I-cycle-through-my-data-points-to-see-which-ones-are/m-p/2088006#M89183 <P>Hello,</P> <P>I have a lasso example on a picasso.js scatter plot at this JSFiddle:&nbsp;<A href="https://jsfiddle.net/3sbvwpxa/" target="_blank">https://jsfiddle.net/3sbvwpxa/</A>.
