How can I set Tooltip to emerge when pressing definite keyboard button? All my mouse button are needed for other things, hover is not good variant. If my memory serves me correctly in first versions there was possibility to show tooltip on Ctrl button.
As far as I’m aware it’s not possible to show a tooltip on keyboard. The problem is in WPF keyboard focus might not be on your chart, so unless the user specifically clicks to focus a chart then presses a keyboard button, it won’t show.
We do plan to add more keyboard support in SciChart v4, which will be released later this year.
