I think i have to detect is Axis(Left or Right) Maximum Value bigger than 99999 ..Then i will format Axis's values ..

is valueFormat property has "divide 1000" ability?

It doesnt work ..Because Left Axis has labels like that (0,20000,50000,150000,300000) ..
I have to show this values as (0,20,50,150,300)
With your advice this values seem as (0,20000,50000,150,300)..

I want to open ContextMenuStrip when user right-click CustomPoint(Line,Area,Bar etc..).But
because of Steema's CustomPoint class doesnt inherit from System.Windows.Form.Control class,
it hasn't got ContextMenuStrip Property ...
How could i resolve this problem ?

I want a chart has fixed label size for left-right axes.. But when i set to label size big numbers couldnt seen .. If value of axis bigger than 99999 (for example 200000) i want to show it as 200 (by divide all values to 1000) .. So i have to add Legend at bottom of the axis... What is the best way ...
