Re: To display map scale

Sorry for the delayed answer.
Could you give visual representation of your question.
My current understanding is based on assumption that want some scale-bar on the map. Is it true? There is some problem with 'scale' on the Earth's map. See for example this Wiki article.

Re: AddSeries() add more point than expected point count.

Starting at least from v8.4.2.4001 issue should be fixed.
That is, points adding order and disabling/enabling PointCountLimitEnabled have no side effect (behaves as expected).
Therefore, it should be no data loss.

Re: Axis SetRange problem

Hello Jürgen,

I am guessing that ScrollMode and ScrollPosition on x-axis are interfering.

Please set axisX.ScrollMode = XAxisScrollMode.None; before setting range.
Alternative, axisX.ScrollPosition should not be bigger than Xmax (default ScrollPosition=0).

All the best.

Re: viewxy - annotation x axis values changed between v7 and

Just quick question. Why you are not using ConstantLine as splitter. This is much simple object and automatically rendered between X min-max. The usage could be found in our Demo App example "Segments with splitters".

All the best.

Re: Exception from ViewSmith

Hi Lokesh, I just tested with LightningChart v8.1.2.1 WinForms. I created 40 empty Smith and see no significant difference between HardwareOnlyD9 and HardwareOnlyD11. The memory allocation is about 700 MB and no exception during initialization. It is probably specific to version you are using (which...

Re: .TimeString with day count > 1 month without day rollove

Hello Heather, You could set Axis type with xAxis.ValueType = AxisValueType.DateTime; Now all the values on the xAxis assumed to be in seconds. And offset of time is controlled by DateOrigin properties, e.g. xAxis.DateOriginYear = 2011; xAxis.DateOriginMonth = 1; xAxis.DateOriginDay = 1; The dates f...

Re: Drag Series Plot to New Form?

Hi Lokesh, The drag-drop of Series is design to work with 'drop-point' being active-area of x/y-axis. The increasing zone to ViewXY area would create unnecessary uncertainties: e.g. in case of multiple axis layout. Series have DisableDragToAnotherAxis property, and it must be set to False to enable ...
