Re: Change colour on LightningChart
Hello,
You can try changing the Border property.
This changes the color of the orange border around the chart. There is also Border.Visible, which can be used to hide the whole border if needed.
Best regards,
Lasse
You can try changing the Border property.
Code: Select all
_chart.ViewXY.Border.Color = Color.White;

Hello, The segments automatically merge if the chart sees that there isn't enough space to draw them. This behaviour cannot be completely disabled. However there are several properties in AxisLayout, which you can try to control segments and any Y-axis belonging to them. _chart.ViewXY.AxisLayout.Aut...

Re: Charts completely black when drawn while not visible

Why this behaviour happens is still unclear and we have to investigate it further to determine if this is a bug...

Re: Control zoom and pan on 2D contour
Hello Jose, PanningEnabled -property prevents panning the chart to the direction of the axis when dragging it with mouse (hold mouse right button and drag by default). It does not affect dragging the axis itself. Here are the properties which control various zooming and panning interactions. They ca...

Hello James, We investigated this issue and found out currently there is no setting, which allows the map coordinates to behave correctly when crossing the International Date Line.

In Smith chart the data is plotted in real and imaginary values (Impedance = R + jX). Since Real values (R) can be seen as horizontal x-axis and Imaginary values (X) vertical y-axis, changing Zoomcenter to a different Real value without changing its Imaginary value causes horizontal pan.
