For that to coordinate correctly after zoom I suggest that you set it up in the following way: ...

Re: icons or small images on the graph

...one point to add. I described how to make the icon visible or not according to mousemove location. That may have missed the point a little. To actuate a link or "further process" when clicking in the zone, use the mousedown event and confirm that the boolean "zoneTrue" is active to actuate or not...

Re: Dependencies of Steema.TeeChart.NET

Hello Lukas, A question whilst we study options. If we split TeeChart.Server.dll from the core Nuget, can we be sure that would that resolve the beta-dependency issue you comment on? ie. Is it correct to assume that you are working on a different platform (eg. Winform or WPF)? With thanks. Regards, ...

Re: How to add custom legends based on canvas painting

Hello, You can draw it via rectangles, index positioning the rectangles and use the fillbrush from each Series (or point) to which the legend item is related. I recommend using Chart relative positions not absolute positions, to locate the Legend. There are some examples (without the coloured rectan...

Re: newCursor = "ew-resize" not working

Hello,

eg.
Chart1.series.items[0].cursor = "e-resize"; // ..or... "move"; //"n-resize"; //"default";

Re: Tee Chart for Angular & Draw a Painting Manually

Hello,

This example (mousedown-drag line draw) includes code that I think is relevant to what you want:

I'll have a look to porting some elements over to the angular example,

Re: How can I use palette color or multiple grid color based on data range ?

Hello, This is normally achieved by using the series.colorEach property but that influences the colour of line-pointers (when visible) and not the line itself, We are modifying the TeeChart code to include colorEach for the line segments themselves.
