When I have cursor tooltips enabled, showing the y-values, they display properly until the y-valuse for the 1st series is below the axis y-min. Below the tooltip y-values are showing correctly
If I move the mouse to the left, below 25 Hz, the tooltip disappears as below.
How can I correct this?
Thanks,
Robert

It appears that I cannot move the annotations outside the chart area. I’d like them positioned below the legend.

But I see you answered my post while I was typing, so I’ll give your suggestion a try.

I’m getting closer. I have
I added the checkboxes to enable the series, like the LegendModifier does by default. But I have no idea how to bind it.
I’ll look through the examples for a clue.

Checkboxes bind to RenderableSeries.IsVisible. Check out the SeriesInfo documentation for what you can bind to. http://support.scichart.com/index.php?/Knowledgebase/Article/View/17249/42/seriesinfo---the-series-viewmodel-for-legends-tooltips-rollovers Best regards, Andrew

Thank you. I bound the checkbox to the bool IsVisable:
<CheckBox Grid.Column="0" IsChecked="{Binding Path=IsVisible}"/>
This works, except the checkboxes that are checked disappear while moving the mouse.
They reappear when you stop moving the mouse.

I attached a simple project that shows the flickering checkboxes.

I am considering applying server-side licensing for my javerScript application.
In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support-dev.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)
However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)
I wonder if there is a sample code implemented in C++ for server-side licensing.
Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

Hi Andrew,
I am pretty certain that it has nothing to do with the not having enough space.
Currently I have:
The tool tip is no longer changing its y-location as you mouse left-right. But, when the y-value of the 1st series is a bit lower than the chart min, it still disappears, like this:
In my case, I think having the tool tip move about with the chart isn’t desirable. I am currently trying to have a fixed area for x-y display. In this case I am using a RolloverModifier. So far I have this:
I used the example from RealTimerCursors.xaml. What I need to do is position the y-values below the legend and perhaps remove the colors, etc. Or combine with the legend and its checkboxes.
I would like to know how to remove the fat y-crosshair.
My code so far is below.
Thanks,
-Robert

Hi Robert,
Sounds like you are on the right track. To style or remove the rollover line, please have a look at the article Adding TImeSeries Tooltips with the RolloverModifier and scroll down to the section Styling the Rollover Line.
To move the rollover cursor elements below the legend, well, you could actually combine the legend & rollover info. Why not template the Rollover readout to display the info about the series including the series name, line style and visibility checkbox?
Basically the LegendModifier and RolloverModifier just output a series of ViewModels that you can consume and the SciChartLegend is simply an ItemsControl with an ItemTemplate. You should be able to achieve quite a deep level of customisation given a little work.
Take a look at SeriesInfo – The Series ViewModel for Legends, Tooltips, Rollovers and SciChartLegend ItemsPanel and ItemsTemplate for some ideas.
Hope this helps!
Best regards,
Andrew
