Hi All
By default legends are being draw on scichart surface. I want to draw them outside the scichart surface because as the number of render-able series increase legends hides them. Please give me suggestion how do i do it ?

In our view model, the data range is expanded to include data outside of the X-Axis range. This is done to preserve the spline curve which is defined by previous points– doing this prevents the spline curve from changing drastically by including X number of points outside the range.

When the Draw function is called, the point context that was bound in is filtered to the X Axis range which leads to the spline curve changing as you pan (especially noticeable if it affects a peak).

How can I change this behavior to preserve the spline line?

Updated — Setting ResampleMode = None does not give me all the points.

I’m looking to either extend the RubberBandXyZoomModifier to provide this size growing behavior when the mouse has left the chart area (shown in the attached image) or build one from scratch (having to rebuild the normal box-zoom components (the box etc).

I assume from reading around the the latter option will be the only option.

Thanks!

Is there an example of building a custom axis using a long or ulong?

So far I’ve tried implementing AxisBase and created necessary types for the given interfaces (IRange, IDeltaCalculator, IAxisDelta). But after implementing the minimum set of pieces, the chart comes up blank.

Also strangely the only two functions that get called on the AxisBase implementation are

GetDefaultNonZeroRange()
IsOfValidType() — This gets called with a DoubleRange rather than my ULongRange.. Somehow a DoubleRange is being introduced, but I can’t see how.

Is there any good documentation/design info out there about how to do this?

I have attached the solution I’ve been working with.

Hi,

I’m looking for an annotation that have text and a line or rectangle (like in commix speech balloon) that are anchored to a point on the chart.
Is there such a build in annotation or do I have to build it myself?

Hi!

We are considering using SciChartScrollbar in a WPF form as a standalone usercontrol – but is this possible? What we are after is to use the scrollbar to make the user able to easily select a range a data, but without(!) the visual chart..

In the examples I have found, SciChart gets its data by binding the property “Axis” to the name of an axis of a SciChartSurface on the same form. So is it possibe to use our own data source?

Best regards,

Øyvind Sannerhaugen
