Creating draw-data for each charting object and creating chart-image from all that draw-data are two independent processes. Adding/removi...

That is default Axis' label orientation. There is no public TradingChart property to modify it. It is possible to access it as internal chart object and modify angle or other style var xLabel = _chart.GetInternalChart().ViewXY.Annotations[0]; However, it may become more difficult to maintain.

Re: How to make Axix range to fix?

Hi,

If you don't want XAxis to change you can:
1. Set ViewXY.ZoomPanOptions.MouseWheelZooming = Vertical
2. Set ViewXY.ZoomPanOptions.AxisMouseWhellAction = None
3. Set ViewXY.ZoomPanOptions.PanDirection = Vertical
4. Set ViewXY.XAxis.MouseScrolling = False

Is this what you need?

Re: Panning to the left zooms the XY chart

LightningChart has a lot of events, which could be used to change the behavior of the Chart. You may use XAxis.RangeChanged , YAxis.RangeChanged , ViewXY.BeforeZooming , ViewXY.Zoomed , ViewXY.BeforePanning and ViewXY.Panned events. I believe that with one or combination of event handlers you should...

Re: UI Automation around Markers

EventMarkers (as any other LightningChart item) have event handlers for mouse actions. Those include mouse hover (MouseOverOn, MouseOverOff), click etc. There is also PositionChange event, which is raised then Marker is moved by mouse or value(s) changed. It should not be difficult to create desired...

Re: How have stair line

Thank you Curt for the feature request. Unfortunately there is no easy switch to stair-like line rendering. It is not only about line rendering itself but also about all other features and optimizations connected to the line Series: for example, X-Axis scrolling optimization, value tracking with cur...

Re: Panning to the left zooms the XY chart

Hi, For the start, you are using very old version. However, even in old version I don't recall such problem/bug. And definitely it is not the feature. Most likely some properties or event handler are set wrongly. It is difficult to say where you get it wrong without seeing code. Check our tutorials ...

Re: Intensity grid throwing error on minimize

Hi there! There is very specific reason why this error is thrown. That is, if manual margins are set ( ViewXY.AxisLayout.AutoAdjustMargins = false ) and window size is just too small to have positive GraphArea, XY drawing is cancelled and error is raised. Personally I believe that ' Unspecified ' Er...

Re: How to create scrollbar for legend box in WPF

Hello,
You should disable AutoSize property and modify Height according to your needs. Otherwise LegendBox is always automatically sized.

Re: IntensityMeshSeries with different amount of columns per

Intensity series (Grid or Mesh) is array of M x N nodes and you should fill all the nodes. For IntensityMeshSeries X & Y values initialized as 0. Therefore, you are getting broken image as you described, if you are not setting values for remaining nodes. In your case, either yo need to arrange p...

Re: Barchart issue with aligning the bars with the custom ti

Hi, If you want place Bars at particular value of XAxis, you should set lightningchart.ViewXY.BarViewOptions.Grouping = BarsGrouping.ByLocation; The default option ‘ ByIndex ’ and another option ‘ ByIndexFitWidth ’ will not rely XAxis. Instead Bars are drawn in the center of the chart without any bi...

Re: Barchart issue with aligning the bars with the custom ti

Hi,

What are the settings for BarViewOptions (especially Grouping)?
Could you send whole project to Arction's support account for testing?

All the best.

Re: Severe lag when moving mouse on temperature demo

No, it is not normal that mouse movement alone is causing application to lag. I believe you did some modification in example. If yes, we would like to know what kind. If no, then it must be some problem with graphic or mouse drivers. Please send DxDiag output for inspection. Mouse movement on top of...
