This is Sai,
In my web application as a user I will put some points on the bar chart(which contains X and Y axis) and then when I click on button all the points should join & form a shape and when I drag and drop that particular shape to other place in that bar chart it should able to read the chart coordinates and I can able to resize that shape.
Like this there are many shapes in that bar chart.
How to do this??
I don't know any charting mechanism for bar charts which allows us to create movable,resizeable shapes that is why I have taken table and divided each <td> like a block so that each <td> contains an id its row and column no
for example row 2 and and column is 5
then its id is 25.
Now in order to place any Irregular shapes I have taken canvas to place shapes, now the problem is all the shapes are on the canvas it acts like a invisible layer and while drag and drop any Irregular shape entire canvas is moving not the single shape.
and what I want is I need to record to where that irregular shape is dropped.
