Hello Pasi,
how can I show in the Legend box listing the icons?
I tried it with the following settings.
Code: Select all
_chart.ViewXY.LegendBox.Position = LegendBoxPosition.TopLeft;
_chart.ViewXY.LegendBox.Offset.SetValues(75, 0);
_chart.ViewXY.LegendBox.Fill.Style = RectFillStyle.None;
_chart.ViewXY.LegendBox.BorderWidth = 0;
_chart.ViewXY.LegendBox.Shadow.Visible = false;
_chart.ViewXY.LegendBox.ShowCheckboxes = false;
_chart.ViewXY.LegendBox.ShowIcons = true;
_chart.ViewXY.LegendBox.Layout = LegendBoxLayout.HorizontalRowSpan;
_chart.ViewXY.LegendBox.MoveByMouse = false;
_chart.ViewXY.LegendBox.MouseHighlight = MouseOverHighlight.None;
_chart.ViewXY.LegendBox.HighlightSeriesOnTitle = false;
However, it now looks like this.

If series.PointsVisible = true, it shows the series PointStyle icons. If PointsVisible = false, it shows just the line.
Are you using SeriesEventMarkers to show the points? If so, add 3 extra PointLineSeries objects, where you have PointsVisible = true, and putting same PointStyle there than in markers. Then you have 6 items in the legend. Remove the extra (line) items by setting their Title.ShowInLegendBox = false.

Hi Pasi,
is there a possibility to hide the lines in the icons?

for the series that represent the icons in the legend box set their series.LineVisible = false.

Hi Pasi,
the lines should be hidden only in the legend, not on the chart.

Yes, exactly. You must have
A) different series objects for the chart data
B) different series objects for the legend symbols
for series of B, set LineVisible = false.

Hi Pasi,
Using this technique where we have a set of "dummy" series added to the legend for the sole purpose of displaying the icon correctly we lose some other important aspects of the chart.
Most notably we lose the ability to automatically highlight the corresponding series on the chart when hovering over a legend entry.
Is there some other way to achieve this? For example I've attempted to handle the various MouseOver events on the LegendBox but can find no way to extract the series information from either the event nor the legend.
Any suggestions?

There is SetHighlight method you can call for the actual series in the SeriesTitleMouseOverOn handler of your dummy series. And RemoveHighlight method to call in SeriesTitleMouseOverOff handler.
Ensure your are using 6.2.4, older had some problems in this regard. Also set LegendBox.MoveFromSeriesTitle = false.

Hi,
Under normal condition LightningChart don't make interpolation/extrapolation/downsampling/upsampling. If you see some extra lines/points it must be bug in your code or in our library.
However, your image looks peculiar. First, it show that you are running quite old version of LightningChart, but somehow still in trial mode. Second, as far s I could see, your 1st point coordinates {100,0}. That is, x values starts from 100.
If you still have a problem, please update to latest version of LightningChart and send/upload your script to Arction's support or forum.
P.S. Please, create new topic in the forum, if it is not relevant to any other question asked before.
All the best.
