<h4>Save graph</h4>
|
|
In some browsers when used display method "Canvas" you can save graph by clicking it with right mouse button and selecting "Save image". Also you can save 3D-graphs.
|
|
<br/><br/>
|
|
<h4>Offset</h4>
|
|
If graph isn't in the right place (larger than canvas) then can you set necessary parameters graph displaying in settings menu.
